Think muscle building steroids and you literallyhave your hands full with choices.
But when it comes to cutting compounds, there are only a few that are really effective.
The rest are just gimmicky, or will only behelpful if you are very lean to begin with.
Among the ones that work are Albuterol,Clenbuterol and DNP.
We wouldn’t touch DNP with a barge pole. Notunless we want to be cooked to death from within. That shit should be eradicatedfrom the face of the earth to be honest.
And Albuterol isn’t half as effective as Clen.
That leaves us with Clenbuterol, the mostpopular cutting drug of all times.
Used by everyone from athletes to bodybuildersto the couch addict.
If you are looking to shed, Clen is what youneed.
Here’s the low down on this very, potent fatburning drug.
What is Clenbuterol?
Clenbuterol is a veterinary grade decongestantand a bronchodilator that was originally prescribed to horses for the treatmentof asthma.
Don’t let the veterinary bit scare you. It isapproved for human use in several countries, barring the United States. Whichisn’t too surprising if you ask us.
Clenbuterol has a two-pronged approach forasthma treatment.
It thins the blood to reduce pressure in theairways and also widens the airways increasing the amount of oxygen in theblood.
In a bodybuilding setting, where it is morepopular, it works by stimulating the central nervous system and the heart, much amphetamines. This in turn, amplifies the metabolism by up to 10%.
That might not seem much on paper. But in effect, it’s your body burning fat 24×7.
You will feel more excited, your heartbeat willbe high, your body temperature will be high and you will feel focused anddetermined.
Even normal walking or mild exercise will amplifyfat burn. There’s no need to perform HIIT.
Having said that, Clenbuterol is a very potentdrug and one that deserves a fair bit of respect. More on this in a bit.
What does a Clenbuterol pill look ?
Clenbuterol pills are small, round and white.Some brands also offer these pills in yellow, green and orange lately.
But the white version is the most popular one.
The lowest available dose is 10mcg. But tabletsare also available in 20 and 40 mcg doses.
UG labs mostly stock German made Clen frombrands Balkan Pharma. But there are many Indian brands that are cheaperand equally effective, since the drug isn’t controlled in India.
Clenbuterol is easily available to buy and there is no risk of counterfeiting.
However, we’d steer clear of what’s sold asliquid clen these days. Liquid is easier to use than swallowing multiple pills.We get that.
But we have seen numerous instances where theliquids were improperly dosed.
What if you want to use 40mcg/ml and end uptaking a 100mcg dose instead?
Pills are safer. Stick to the tried and testedmethods.
What are the results that you can expect from Clenbuterol?
We all know that Clen is a very powerful fatburner. But is that it?
Nopes. There’s more to the drug.
Here are some of the results that you canexpect from a Clenbuterol cycle.
Focus and attention:
Clenbuterol is a powerful stimulant and it will keep you alert and focused all day. Think of it being on 5x your regular dose of Caffeine. But un ECA stacks which have a spike and then a crash, you will have razor sharp focus all day while you are on Clen.
Clenbuterol is mildly anabolic. Well, it is anti-catabolic to be precise. But since it is mostly used in a stack along with other anabolic compounds, it helps amplify the effects of those compounds to an extent.
So, if you add it to a cutting cycle, it not only burns fat but also helps you retain your hard earned muscle.
The mild anabolism also makes your muscles appear harder and more vascular while you are on Clen.
Clenbuterol increases your metabolism by 10%. It also increases your core body temperature by a few degrees. This forces your body to use stored fat reserves for energy. It is frequently used during PCT, which allows the user to eat in a calorie surplus without the risk of gaining a lot of fat.
- Focus and attention
- Mildly Anabolic
- Fat Loss
What are the side effects of Clenbuterol?
For most users, even the lowest dose of 20mcg provides reasonably good results. This low a dose is well tolerated and the side effects are manageable.
But most users use Clenbuterol in short cycleswhere the dose is increased every day until they hit a sweet spot where thesides aren’t too bad.
However, this increases the risk of sideeffects manifold.
Jitters: The first thing that most users notice is the jitters or tremors or whatever you want to call it. It can last all day at times. But usually stops on its own once the drug is discontinued.
Insomnia: Once again, usually felt at the high doses.If you find it difficult to sleep, just dial down the dose or stop using it fora few days. And then resume with a lower dose.
Musclecramps: Clenbuterol depletesthe levels of potassium which can cause severe cramps. Many bodybuilders uptheir dose of bananas or use potassium supplements to counter this.
VentricularFibrillation: Readpalpitations and irregular heartbeat. Pretty scary. The risk of this happeningapparently increases if you supplement with taurine while using Clenbuterol.
Hypotension: Last but not the least, Clenbuterol can causea fatal drop in blood pressure at high doses.
PCT during Clenbuterol cycles
Well, Clenbuterol is not an anabolic steroid. So, a PCT protocol is not really required.
However, it does cause some serious sideeffects even at low doses. Also, it depletes potassium and Taurine levels.
Some supplementation will make those sides alot more manageable.
the N2guard. It has a blend of vitamins, minerals and herbal extracts that should keep the muscle cramps down.
When most guys hop on their first anabolicsteroid cycle, they have wrong expectations from it.
They expect to gain a truckload of musclewithin few weeks. And end up eating a pig calling it a ‘calorie surplus’.
To their surprise, they earn a wee bit ofmuscle and a truckload of fat and water.
That’s when they start to look at drugs that can help them cut during the PCT.
The first and commonest name that they comeacross is Clenbuterol or Clen.
This asthma prescription medicine became a fat burning staple when Ephedrine, a more powerful stimulant was banned in the United States after its use was linked with multiple deaths.
Clen is undoubtedly safer than Ephedrine but still a very powerful drug that can cause some serious side effects.
It is crucial that you know how to use it andhow to manage some of the milder sides that will be unavoidable when you startusing it.
Here’s a small guide that explains whatClenbuterol brings to the table.
When to use Clen and what results can you expect from it
Clenbuterol is a stimulant. Not an anabolicsteroid, although it is commonly mentioned alongside other anabolic steroids.
This means that you can use it even if you arenot a steroid user.
And to be honest, you will burn fat with Clen even if your diet is crappy and you don’t lift.
But the results will be a lot more pronouncedif you are dieting and exercising while using it.
Users who are lean to begin with (13-15% bodyfat) will find it most effective as it can easily help them drop to below 10%body fat, allowing those abdominal muscles to pop out.
Clenbuterol is normally used only in cuttingcycles due to the amplified fat loss. It is also touted to be mildly anabolicwhich might help in preventing muscle loss as you lift in a deficit.
Many users add it along with a powerful mass building steroid, Testosterone for body recomposition, particularly towards the end of the cycle. The results are phenomenal to say the least.
What are the risks of using Clenbuterol?
Well, if you are careful with it, you can useit with very few side effects and get some great results.
But if you go overboard with it, (very easy tooverdo clen), then you start to experience some of the nasty side effects thatcan take a severe toll on your health and wellbeing.
In fact, there are tons of guys who hopped onto Clen and then dropped the cycle just as quickly because the sideswere unmanageable.
Clenbuterol is typically dosed starting with a very low dose and increasing it every day until you hit your threshold of tolerance towards it. Once you do hit the threshold, the first thing that you notice will be the tremors. It can be pretty scary with your hands shivering all day. Some users even shake subconsciously. Thankfully, the tremors will stop when you discontinue the drug.
Once again, the insomnia usually hits when you are dosing at your peak. But it can be so severe that you might be unable to sleep all night for a few days. Some users use Benadryl for a couple of weeks during their Clenbuterol cycles. It supposedly helps negate the insomnia. We have never tried it ourselves.
Clenbuterol also depletes potassium levels in the body which can cause severe muscle cramps. That’s one of the reasons why HIIT is not recommended while you are on it. Drink plenty of water during the cycle and use any OTC joint supplement to minimize this. Clenbuterol also works compliments Deca Durabolin very well and the two are often stacked together.
After a few days of use, Clenbuterol can deplete the levels of Taurine in your liver, heart and lungs. Taurine protects these organs.
But when users supplement with exogenous Taurine, it increases the risk of causing Ventricular Fibrillation, a severe condition which causes palpitations and erratic heartbeat patterns. In extreme cases, this can cause death. The risk of VF is higher in people who are predisposed towards cardiac conditions.
Recently, a popular bodybuilder died in a Thai Sauna. He was using Clen and had an undiagnosed heart condition which might have contributed towards death.
Clen can also drop your blood pressure to alarmingly low levels. A condition that requires immediate medical attention and may also be fatal.
How to use Clenbuterol?
Start with the lowest recommended dose of 20mcgper day and then keep adding 20mcg each day until you reach a comfortable dosethat doesn’t cause too many side effects.
You can use it for two to four weeks dependingon your fat loss goals.
Many users use it at a steady dose for twoweeks and then taper the dose for a couple of weeks to minimize the risk ofside effects.
Others continue to use the same dose throughouttheir cycles. It depends on how you react to the drug to be honest.
If you find that the side effects are becomingbothersome, then come off Clen for a couple of weeks and then restart thecycle.
Clenbuterol is one of the most powerful fatburners in the world. But one that comes with severe ramifications.
Use it at your own discretion. And never use ituntil you have your diet in order.

Clenbuterol – Higher The Risk Of Side Effects
Clenbuterol also known as Clen is famous amongst the body builders and athletes as it helps them to achieve their desired physique by working on the right parts of body to burn fat.
It has been recognized as a growth promoting drug often used by athletes/body builders as it helps to increase aerobic capacity and their performance.
After being used by many celebrities as well for a zero size figure, it is also called a “size zero pill”.
With a proper workout routine and a healthy diet, great results can be seen by the use of Clenbuterol. However, higher the risk of side effects if the dosage is not taken properly.
None of the supplements are free from side effects. The short term side effects of Clenbuterol are:
- heart palpitations
- Increased heart rate
- Dry mouth
- Breathing difficulty
- blood pressure
- muscular tremors
- increased appetite
- Abnormal sweating.
These side effects can be minimized by following a safe dose and drinking a lot of water while on a Clen Cycle. Otherwise, these side effects would anyway vanish once Clen will be stopped.
In the long term side effects, Use of Clen in animals showed that it increases collagen. This non-elastic substance increases the size of heart muscle cells and interferes with the electric signals sent to heart to pump blood.
Due to this, the rate of pumping of blood is interfered. This may cause irregular heart beat and will include the risk of stroke. Clen can also get some structural changes in heart and may result in sudden death.
And the long term use of Clen with people suffering from some heart diseases may cause serious problems.
Some studies have also revealed that Clen can be harmful to bones as it increases the bone fragility. And bone fragility with an increase in muscle mass increases the risk of fractures.
Prolonged usage of Clen can also cause severe side effects of stroke, Hypophosphatemia(a condition of low levels of phosphorus in blood which causes chronic diarrhea, malnutrition, burns or uncontrolled diabetes),Tachycardia(increase in heart beat),Hypokalemia( low potassium levels which causesWeakness,Fatigue,Muscle cramps,Constipation,abnormal heart rhythms).
Clenbuterol is famous for its weight loss feature. What many do not know is that this weight loss is temporary and you will soon start to gain weight. In case of long term use of Clen, sudden and intense weight gain has been noticed in people.
This is due to the impact on body’s metabolism rate which is disturbed over the time. People, who suffer weight gain after Clen, often complain of more weight gain than they used to have earlier to Clen.
And the only way to keep up the weight loss after stopping Clen is to keep up with a healthy diet and proper exercise.
In order to avoid the long term and risky side effects, one must take the prescribed amount of dose only. Never overdose or take it for a longer time than prescribed.
Clenbuterol: The new weight-loss wonder drug gripping Planet Zero
As cruel as it is to break the news to Louise Redknapp at just this point in time, dieting as a route to size zero has suddenly become as passé as last season's hem-line.
Earlier this month on ITV, the former popstrel and footballer's wife endured a brutal diet and exercise regime in order to “lose her trademark curves” (she is a UK size eight) and crash-diet her way Hollywood size zero.
She lost the weight, along with her social life, her good health and her joie de vivre.
But now you don't need to starve yourself to join the s of Victoria Beckham, Lindsay Lohan and Nicole Ritchie on the farther reaches of emaciation.
The latest celebrity diet secret makes the fat melt away without anyone having to lift a finger – or a stick of celery.
It is called Clenbuterol, it is the new weight-loss wonder drug, and it is rapidly becoming the axis on which Planet Zero spins.
Those who claim to be in the know have named Clenbuterol the celebrity quick fix of the season. Recently, on the gossip website Popbitch, one spoilsport pointed the finger.
“LA's current concentration-camp look isn't just the result of cocaine and eating disorders,” said the post. “Everyone's doing Clenbuterol. Prescribed as an asthma medication, [it] is taken by body-builders and now weight-watchers for its amazing fat-burning qualities.
.. ever wondered why celebrities always seemed to be hospitalised for asthma, dehydration and exhaustion?”
Sharing the full story, not just the headlines
The website is approximately right: Clenbuterol is a steroid- chemical, initially developed to alleviate asthma symptoms in horses by relaxing the muscles in the airways.
Its stimulant effect on the heart and central nervous system mimics the actions of adrenalin or amphetamines, and it is also used in animals as a partitioning agent – a substance that increases lean muscle mass and reduces fat deposits.
Clenbuterol is illegal in this country for human or even animal use, to treat asthma or anything else. This is because it causes side effects, such as palpitations and arrhythmia [irregular heartbeat], and has been responsible for several cases of poisoning in humans. This may not trouble Planet Skinny, but it is seriously worrying doctors on both sides of the Atlantic.
In most countries in Europe, Clenbuterol is forbidden for use in animals that will enter the food chain. But that does not always prevent its use. Because it increases muscle definition and reduces fat, livestock are often dosed with the drug to make them appear more attractive to buyers.
In Spain in 1994, 140 people were hospitalised after they consumed meat tainted with the drug and suffered dizziness, heart palpitations, breathing difficulties, shakes and headaches. Just over a year ago, the Chinese newspaper People's Daily reported that 336 people in Shanghai had been poisoned after eating pork tainted with Clenbuterol.
The drug had been banned by the Chinese government in the 1990s.
Last week a Home Office spokesman told The Independent: “Clenbuterol is a hormone growth stimulant and a Class C drug. It is an offence to supply or have intent to supply Clenbuterol.
There is no possession offence – although obviously if somebody had so much that they seemed to be intending to supply, they may be prosecuted.
It carries a maximum sentence of 14 years imprisonment and/or an unlimited fine.”
The rules seem straightforward, but obviously people are getting hold of Clenbuterol somehow.
Its use has increased since steroids were banned in sports in the 1990s, according to the British Medical Journal, and now diet junkies are logging on to bodybuilding messageboards and asking posters for advice on how to use it.
Clenbuterol is also banned by the International Olympic Committee, but non-competitors don't mind using it. Their advice to dieters looking for a source: buy it on the internet.
A quick google search for “buy Clenbuterol” turns up more than a million matches. The first of them is a website called Clenbuterol King, which pleads with potential customers: “Don't listen to the sales sites. Get the real info.
” Posing as a concerned potential customer, I e-mailed their advisers. “I have used Clenbuterol myself (and I mean that sincerely),” came the reply. “I have battled with my weight ever since I can remember, but Clenbuterol is the kick-start I needed. I was 96kg and am now 84.5kg.
” The site was also keen to stress the celebrity connection – confirming that they, too, had heard the rumours about the particular names I mentioned. “We do have a number of stars on our books,” I was told. “Naturally I can't give you names.
But yes this is the weight-loss tablet of choice for those in Hollywood. This medication was their secret.”
When health concerns were raised the spokesperson was reassuring, suggesting that I had a general check-up with a GP and read the contraindications on the website. Otherwise, the line was: “I've taken it and I'm fine.” The Clenbuterol King website says it can post 200 20mcg tablets to the UK for $160 (£85), within seven days.
The site is quite realistic when it comes to side effects. “Because Clenbuterol is so good at what it does, you will ly experience… muscle cramps, increased blood pressure, increased energy [and] slight shaking,” it says.
It suggests eating bananas to combat cramps and advises not taking Clenbuterol after 3.30pm as it may induce insomnia, and not too close to a workout because it can affect breathing.
It also warns that users may experience nausea, dizziness, drowsiness, tremors, dry mouth and vomiting. And this is the site that is trying to sell it.
Strange as it seems, those who have used the drug talk of even more frightening side effects. An anonymous user posting on a messageboard based in the States wrote: “I got some cramps in my calves, feet and hamstrings.
They hurt A LOT!!! I didn't have a problem sleeping or any other sides… besides the increased heart rate. Resting I was at 90 beats per minute…” Weightlifters' forums discussed the drug in terms perhaps characteristic of their sport. “I was sweating a rapist,” said one.
“Just one [tablet] gives me 'speed dick',” replied another.
A user who recommended Clenbuterol as a diet aid described an accidental overdose. “Maybe my vitals would help a little. My heart rate when I got to the ER was 178 and at its peak about two hours later was just above 200.
” Another user who claimed to have discussed the drug with a doctor warned: “What people need to know is that Clen is a dangerous drug and [it's] un steroids. Long term side effects such as left-sided cardiac atrophy can occur very quickly – in as little as one month in some cases when taken in high doses.
Other side effects can quickly occur when overdosing: tachycardia [sudden, rapid racing of the heart] hypokalemia [elevated levels of potassium, potentially leading to fatal arrhythmia], hypophosphatemia [depleted phosphate levels], potassium depletion, taurine depletion, headaches, tremors, and vertigo…
” What was most alarming about these posts was that none of them advised stopping taking the drug: they were all too entranced by its effects.
So, if a drug this dangerous is entering the country so easily, shouldn't the Government be doing something about it? Well, it is – after a fashion.
A spokesman for the Medicines and Healthcare products Regulatory Authority (MHRA) said that, because the drug is not licensed for humans in the UK, its control would come under the remit of the Department for Environment, Food and Rural Affairs (Defra) or the Home Office.
Defra said: “Clenbuterol is banned for use in animals. The Veterinary Medicines Directorate checks for [its] presence as part of its residues surveillance and can confirm it has not recently been detected.
Defra and the VMD would be keen to receive any evidence of alleged illegal activity regarding giving this to animals. The MHRA would be able to confirm… the penalties for use [by humans] if banned.”
The Home Office also thought it was the responsibility of the MHRA. “Internet supply is registered by the MHRA, and of course the law enforcement agencies,” a spokesman said. “If a site hosted by a UK service provider contains illegal material, the Home Office would issue an order to take [it] down.
” Outside the UK, of course, there is not much the Government can do. The Home Office added that customs officials use intelligence and detection techniques, including X-rays, to search post coming into the UK from abroad.
If they found Clenbuterol being sent to a British consumer they would confiscate the drug and may refer the case back to the MHRA.
The MHRA was confused. “When it comes to prescription medications or unlicensed medications, the Home Office is right, they are our responsibility,” said a spokesman.
“If somebody has a website abroad selling a medication that is not licensed in the UK, we would contact our counterparts overseas and ask them to take action.
But under the Misuse of Drugs Act, Clenbuterol is a Class C drug, not a medication: it is a Home Office, police or customs issue.”
That said, the MHRA has been working to warn the public about buying drugs online. One of the main concerns, they say, is that “there may be no legal recourse in the event of problem”. A problem sweating, palpitations and rapid weight loss, for example? Somehow that doesn't seem ly to put the dieters off.
Other slimming drugs
Five years ago, the British drug company Phytopharm patented an active ingredient in a cactus- plant called hoodia that is used by the San bushmen of Southern Africa to ward off hunger. Unilever and Phytopharm have been working together to market the product as a diet drug, but the San are battling Phytopharm for some of the £21m they will receive from Unilever, claiming bio-piracy.
GlaxoSmithKline has paid $100m for the US rights to Alli, a drug currently available only on prescription in the US. It works by preventing the body absorbing fat. Steve Burton, the man who developed it, used the drug to lose 60lb.
The International Narcotics Control Board has appealed to the Government to curb the illegal sale of prescription drugs over the internet.
The INCB named 14 appetite suppressants, prescribed to treat obesity, attention deficit disorder and narcolepsy, including Phentermine, which has a 45 per cent share of the world market, Fenproporex (23 per cent) and Amfepramone (18 per cent).
INCB president Philip Emafo warned: “They are being used indiscriminately to feed the slimming obsession. Effective intervention by local competent authorities is a must.”
Taken in the 1950s by desperate housewives keen to lose weight, amphetamines, are still abused by some as a diet drug. By 1948 they were prescribed to two-thirds of weight-loss patients, and in the 1970s two billion pills were consumed, including by children.
In 1893, thyroid extract was marketed under the brand names Frank J Kellogg's Safe Fat Reducer, Corpulin and Marmola. It carried risks of osteoporosis, sweating, chest pain, and sudden death.
Laxative use for weight loss began in earnest in the 1920s. Jane Fonda has described using them as a teenager in order to “have your cake and not eat it, too”.
The benzene-derivative in World War I explosives, insecticides and herbicides was used by 100,000 people in the 1930s. It works by increasing metabolic rate, and side effects included rashes, blindness, and death by hyperpyremia (fever due to increased metabolism).
Why the Performance Enhancing Drug Clenbuterol Is Banned in Sports
Bryn Lennon/Getty Images
Clenbuterol, also called “clen,” is considered a performance-enhancing drug. It's banned from most athletic competitions.
Both the World Anti-Doping Agency and the International Olympic Committee include clenbuterol on their lists of prohibited drugs.
Even so, athletes continue using clenbuterol for its ability to help burn fat, build muscle, and improve performance. This is unfortunate because clenbuterol has been linked to a number of serious side effects.
Clenbuterol is a type of medication that's a selective beta-2 agonist/antagonist and bronchodilator, which means it relaxes the smooth muscle tissue that makes up the airways to allow for freer breathing.
The United States Food and Drug Administration has approved clenbuterol only for use by veterinarians, who may prescribe it to treat horses with obstructive pulmonary disease or other lung conditions.
The trade name for clenbuterol used for horses is Ventipulmin.
The “human equivalent” of clenbuterol is albuterol, which is a prescription-only medication used to treat or prevent bronchospasm caused asthma, bronchitis, emphysema, and other lung diseases, and also to prevent wheezing caused by exercise.
There are a variety of brand names for albuterol, including Ventolin, Proventil, Accuneb, among others. Regardless of whether it comes in generic or brand name form, albuterol comes in an inhaler that a person can use to breathe the medication in through the mouth so it can easily reach the airways.
In the past, clenbuterol was given to livestock to increase lean muscle mass and the overall yield of livestock production. Now it's banned from being used for this purpose in the U.S. and much of Europe.
Even so, athletes who test positive for clenbuterol often claim they must have eaten contaminated meat.
Three-time Tour de France winner Alberto Contador may be the most famous athlete to have used this excuse after testing positive for clenbuterol.
Athletes who use clenbuterol do it to burn fat, build muscle, and improve sports performance. The drug is believed to increase the development of skeletal muscle by enhancing muscle protein synthesis. At the same time, it aids in fat loss by increasing metabolism.
In general, any positive effects of taking clenbuterol seem to be temporary and short-lived.
The effects of clenbuterol on athletes who take the drug over a long period of time aren't known. What is clear is that besides affecting the muscles of the airways, clenbuterol is taken up by other tissues in the body.
Animal studies have shown that clenbuterol use may lead to apoptosis—the death of normal cells—in the muscles, including the heart muscles.
For this reason, veterinarians are cautioned against giving the drug to horses who have cardiac issues.
Clenbuterol may heart attacks and other heart damage, as well as irregular, heart rhythms.
Other side effects of clenbuterol use include muscle tremors, increased perspiration, increased blood pressure, insomnia, headache, nausea, and vomiting.
Athletes who chooses to rely on a banned performance-enhancing drug rather than hard work and practice not only is risking being caught for cheating. They also may be risking their health.

Clenbuterol Review: Side Effects, Uses, Risks & Alternatives 
Anabolic steroids were once widely used for theirextremely effective functionality and results. Steroids are meant to give you atransformed body with enhancement of physical performance. One such popularexample of a steroid is Clenbuterol.
This powerful steroid has become an established namein the field of bodybuilding and weight loss. It helps you lose fat and improveyour body’s physical potential significantly. In little time, it became the #1fat loss anabolic steroid out there.
The immense popularity of this steroid is attributedto the fact that gaining muscle mass and losing weight simultaneously is a realchallenge. It amounts to gaining calories and losing calories at the same time,something which sounds farfetched, to be honest.
But Clenbuterol makes it possible!
What is Clenbuterol?
The administration of Clenbuterol first began in thetreatment of asthma. It served as a bronchodilator and hence, enhanced the flowof air into the body. In addition, it also rounded up as an effective fatburner as it efficiently eliminated the unwanted fat deposits in the body.
The potential was huge and as such, it began to beused in animal studies as well. This steroid started being used in cattle andthe results were astounding. Not only did the tested cattle appear healthier,but it was also noticed that there was appreciable loss of fat in their meat.Basically, the meat from the tested animals was healthier and tastier than theuntested ones.
The message soon spread out about the revolutionaryfat burning and muscle preserving characteristics of this steroid, and thebodybuilding community in particular tool note of this.
No points for guessing, bodybuilders started usingClenbuterol extensively as it achieved the rare feat of fat loss and musclebuilding simultaneously.
Furthermore, the role of the steroid as abronchodilator aided in supplying the muscles with more oxygen, therebyenhancing performance in the gym.
It was truly a dream product for any athleteand the popularity of this so-called steroid proved just the same.
But was it really a steroid?
Is Clenbuterola steroid?
Basically, a steroid is referred to as any substancethat comes with performance enhancing properties. This is the very basic ideaof steroids held by most people.
However, Clenbuterol isn’t really a steroid!
So what is it?
Well, Clenbuterol is essentially an artificialstimulant, similar to ephedrine. Just ephedrine, it offers powerful fatburning functionalities through thermogenesis. This process involves raisingthe temperature of the body and improving the metabolic rate to burn fat.
