Is Clenbuterol legal to use

Celebrities and common folk alike have been using Clenbuterol (Clen) for weight loss, and there are even athletes who use it for a performance boost.

However, there are also questions about Clenbuterol legal status in the US, UK, and other countries.

Another aspect that should be mentioned are the side effects of this drug.

I will try to answer these questions and help you decide whether you should buy and use one or not?

Is Clenbuterol Legal?

The short answer is, Clenbuterol is not a banned substance in the US and the UK.

However, its use is approved only for treating lung-related ailments on horses.

In Canada and the UK, it isn’t illegal to buy and possess Clen if it’s for private use. But it is illegal to buy Clen with the intent to sell or act as a supplier.

The UK, Canada, Australia, and other countries consider buying a large supply of Clen as an intent to supply and is punishable by law. The prohibited amount depends on the exact location.

In the United States, Clen is not approved for human use and can only be legally administered to horses by veterinarians.

Under no circumstances is it legally acceptable to use Clen for weight loss, bodybuilding, medicinal treatment or food preparation.

Outside the United States, the rules aren’t so strict. Clen can be easily bought in China, Russia, and Bulgaria.

In most countries, however, the rules are similar to that in the US, i.e. Clen is not a banned substance but can only be used on animals for treatment of respiratory conditions.

The bottom line: Clenbuterol was approved for use as a treatment for respiratory conditions on horses.

Illegal steroids useIt has very similar properties to bronchodilator albuterol and it’s been proven to work for different types of respiratory ailments for animals.

However, it eventually made its way to bodybuilders, and now it’s being used as a weight loss pill.

The fact is clen was developed for horses, not just for treating respiratory conditions but also to gain muscle mass and less fat. But people who ate livestock that took Clen became ill.

Soon, medical experts began studying the side effects on horses. It became clear the side effects were dangerous which led to strict laws about its use.

To summarize:

  • Clenbuterol is not a banned substance in the US, UK, Canada, and other countries
  • However, the FDA has banned its use as dietary supplement
  • In most countries, you can only buy Clen if it will be administered on horses
  • Intent to sell or supply Clen is illegal in the US and other countries
  • Adding Clen to food or supplements for human consumption is illegal
  • Administering Clen on animals for human consumption is not allowed
  • US and UK laws allow for the use of Clen for treating horses with respiratory disease
  • The IOC forbids the use of Clen by athletes. Other sports organizations also prohibit its use.

How Is This Drug Used and by Who?

Clenbuterol hydrochloride was created as a bronchodilator to relieve the symptoms of asthma.

It was developed specifically for horses but it was later discovered Clen has two “side effects”, stimulating skeletal and muscle growth and promoting weight loss.

Who can use this drugBodybuilders were among the first to use clen for muscle growth, increased stamina and strength. Soon baseball players, runners, boxers and other athletes started using it to gain a competitive edge.

While Clen is best known for weight loss, it is just as potent for performance gains.

Clenbuterol does what is known as repartitioning. When you eat, the excess calories end up as fat reserves. With clen, the calories end up in your muscles, leading to faster muscle growth.

Clen also boosts your metabolism, burning more fat and building more muscle.

As mentioned above, celebrities have also started using it for weight loss.

Its ability to promote weight loss is such that it’s been called a wonder drug. However, what people don’t seem to realize is how dangerous the side effects are.

Losing fat and gaining muscle sounds good, but the problem is Clen also ends up in other parts of your body. Clen enters other tissues including the heart, and this affects their performance.

What are its Most Popular Forms?

Liquid Clenbuterol is one of its most popular forms, but it is also available in pill, tablet, and powder.

While liquid Clen is gaining popularity, tablets are still the most widely used. In terms of potency, Clen is the same regardless of form.

A word about dosage here.

Some websites state that Clenbuterol 40 mg is the ideal dose to start losing weight. Stating 40 mg is not correct, as Clen dosage is measured in mcg. Most women take 20 to 40 mcg for starters and men around 80 mcg.

Clenbuterol in tablet form

The dosage given here is for those who want toot take the drug for weight loss. Those who will use it for bodybuilding usually take more than that.

However the more you take the more likely you will feel the side effects.

If you take Clen, there is a good chance you’ll lose weight and shed off those unwanted pounds. But if Clen is effective, why is its use so restricted?

What are the Dangers of Using This Drug?

The reason for the complicated Clenbuterol legal status has to do with its many side effects. While all weight loss supplements have adverse effects, those of Clen are much more dangerous.

Clenbuterol side effects can be divided into short and long term, both of which are unpleasant.

The short term side effects include:

  • Sweating
  • Difficulty breathing
  • Nervousness/ restlessness
  • Anxiety
  • Tremors
  • Headaches
  • Dry mouth
  • Palpitations
  • Hypertension
  • Muscle cramps

Clen is also a stimulant and that means it has all the side effects that come with it such as acute cardiovascular effects, neurologic side effects, shakes, sweating and a rapid heart rate.

There can also be a sudden spike in blood pressure that could have dangerous repercussions.

Those above are the most common short term side effects. The severity of the symptoms depends on individual tolerance, but all those who take Clen will feel these side effects.

What is known is that acute and chronic side effects both occur and lead to cell death.

There is still research ongoing to determine the long term side effects of Clen.

What is certain is that taking Clen makes heart muscle cells larger. This is due to the increase in collagen leads weakens the heart and makes it harder to pump blood and cutting down its output.

Other possible long term side effects:

  • Irregular heartbeat
  • Stroke
  • Deterioration of heart cells
  • Aortic enlargement after strenuous activities
  • May worsen an existing heart condition
  • Cause high blood pressure
  • Left-sided cardiac atrophy
  • Affect bone microarchitecture and increase the fragility

Usage of liquid Clen

One of the major side effects of Clen is it reduces the heart’s capacity to pump blood. The excess collagen also gets in the way of electric signals which are transmitted through the heart cells.

This interference affects your heart’s pumping capacity and leads to arrhythmia. This is dangerous enough, but this condition also makes you more vulnerable to a stroke.

Several animal studies have also been done which show that Clen contributes to heart cell damage, making you vulnerable to all kinds of heart problems.

It’s well known that Clenbuterol can worsen existing cardiovascular conditions.

Taking high doses can lead to hypertension in as little as a month. As this takes place the rest of your body takes a hit as well. Not only does your heart weaken, but your bones also deteriorate.

One of the most dangerous effects of Clen is it leads to muscle apoptosis or myocyte cell death. It also leads to all kinds of toxicities that could ultimately lead to heart failure.

Some more long term side effects may involve any of the following.

  • Clen may lead to skeletal muscle weakness and failure
  • Bone metabolism deteriorates
  • A testicular function is affected

Effects of Clenbuterol Overdose

Overdosing on Clen is dangerous and toxic. Clen takes time to break down so the effect is felt for a prolonged period.

Once you overdose the effects are quickly felt. These include:

  • Stroke
  • Vertigo
  • Breathing difficulties
  • Tremors
  • Headaches
  • Taurine level goes down
  • Hypophosphatemia
  • Hypokalaemia
  • Tachycardia


The bottom line is simple enough: the Clenbuterol legal status makes it impossible to be used for bodybuilding and weight loss.

Well, impossible to use without breaking the law anyway.

But the legal issues aside, there are also the side effects mentioned above.

So Clenbuterol is not a safe weight loss solution, but there are legal alternatives available like the ones we discuss in this article.
