Clenbuterol Online

Last updated on September 19th, 2018

You have no idea why so many athletes choose Clenbuterol and whether you should use it or not?

Well, it depends on so many things, including your goals and initial stats.

The article will help you figure out Clenbuterol effects and the reasonability of its use, as well as point out several important factors that can influence your results.

What is Clen? Let’s define Clenbuterol. Steroid or not?

Many beginner athletes, who just entered the world of steroids, consider Clenbuterol to be a steroid.

But it’s not. What is it?

Well, in Europe, this drug is classified as a direct-acting beta 2-sympathomimetic agent.

In other world countries, it can be called a beta agonist, beta-2 agonist, beta-2-adrenergic agonist, selective beta-2 adrenergic receptor agonist, selective beta-2 agonist.

Chemistry and Pharmacology


What do all these classifications mean?

Here’s what Wiki says:

Adrenergic Agonists


Just so you know,

  • Molecular formula of Clenbuterol: C12H18Cl2N2O
  • Molecular weight of Clenbuterol: 277.189 g/mol
  • Chemical name of Clenbuterol: 4-amino-alpha – [(tert-butylamino) methyl] -3,5-dichlorobenzyl alcohol.

Now back to more understandable facts…

First, the drug is used for off-label purposes by sportsmen, who want to obtain fast results in:

  1. Fat burning,
  2. Muscle tissue growth acceleration,
  3. Sports results improvement.

Secondly, Clenbuterol is used for off-label use by stockbreeders, who want to speed up the weight gain of cattle, thus increasing their income.

Clenbuterol in bodybuilding

How does Clenbuterol work so well, that so many people use it these days, despite possible risks?

It exerts several effects over the human body.

Those that refer namely to Clenbuterol benefits for bodybuilding include:

  • Stimulation of thermogenesis, thus promoting fat burning;
  • Boosting protein synthesis in the muscle tissue;
  • Slowing down the breakdown of protein.

Thus, Clenbuterol increases muscle fiber size and volume of muscle tissue.

Clenbuterol increases muscle fiber



Low doses of Clenbuterol do not provide a significant thermogenic and anabolic effects.

For this reason, those athletes who want to boast with the most impressive before and after Clenbuterol difference, use excessive doses of this drug.

It is also important that:

  • Muscular endurance is increased at the initial stage of Clenbuterol use.
  • Extended use of Clenbuterol causes muscle weakness.

Thus, bodybuilders and athletes take Clenbuterol in short courses only while preparing for competitions.


The World Anti-Doping Agency included Clenbuterol in the list of prohibited drugs.

Therefore, while getting ready for serious competitions, professional athletes should refrain from the use of drugs, which contain even very low doses of Clenbuterol.

Is there a way to achieve the same results without the risk of being caught on doping?

Yes, there is!

Sportsmen, who want to reduce the body fat percentage without creating the risks to their health, can use safer alternative to Clenbuterol.

You can opt for over-the-counter bodybuilding supplements, which, just as Clenbuterol:

  • Cause thermogenic effect
  • Stimulate the destruction of adipose tissue.

Over-the-counter thermogenic stimulants don’t just burn fats.

They also transform these fats into energy.

Therefore, regular use of OTC thermogenic stimulants allows bodybuilders to maintain:

  • Low body fat percentage
  • High level of muscular endurance.

Over-the-counter fat burners include only natural ingredients that cause no side effects and are NOT considered doping.

Thus, an effective and safe thermogenesis stimulant can be used both during the pre-competition period and on the competition day, as well.

Bonus tip!

Before you buy a thermogenic stimulant, make sure that it burns fats, rather than suppresses appetite.

You don’t need the appetite suppressing effect, since it promotes a decrease in the consumption of protein and nutrients, which are needed to stimulate muscle mass growth.

Drugs, which ensure fat loss and appetite suppression altogether, should be used during the anti-obesity cycles.

Bodybuilders are better to refrain from buying drugs that make you skinny.

Better use only bodybuilding supplements for fat burning, which are developed especially for athletes.

Clenbuterol in animal breeding

Initially, Clenbuterol was used in veterinary practice exclusively for the relief of bronchospasms in farm animals.

However, when the farmers noticed that the drug helps to increase muscle mass and reduce body fat in the animal body, they began using Clenbuterol in animals for:

  • Rapid weight gain
  • Improvement of meat quality.

The first reports on the use of Clenbuterol for weight gain of farm animals were published in the early 80s of the last century.

Multiple cases of food poisoning were reported in the mid-90s of the last century because of the consumption of meat products containing Clenbuterol.

Once it was proved that the clinical intoxication resulted from the drug presence in the meat, it was prohibited in animal breeding.

The greatest amount of this drug accumulates in the animal’s liver, and a small amount – in the skeletal muscles.

Therefore, consumption of liver, filled with the drug is fraught with a higher intoxication risk, compared to the consumption of food cooked of the animal muscle tissue.

The main symptoms of intoxication caused by Clenbuterol are:

  • numbness in the hands,
  • muscle tremor,
  • nervousness,
  • headache,
  • muscle aches,
  • nausea,
  • vomiting,
  • tachycardia.

Intoxication symptoms may appear within the first 6 hours after the consumption of meat containing the drug.

If intoxication with Clenbuterol causes severe side effects, you may need hospitalization.

In the US, Canada, Australia, the UK and other developed countries, the drug is approved as a treatment of pulmonary diseases in horses only.

In countries with insufficient control over the livestock industry, unscrupulous cattle breeders can still use the drug as a growth promoter in animals.

It should be noted that Clenbuterol is not the only “beta agonist”, which cattle breeders can illegally use as a growth stimulant for food animals.

The group of beta agonists includes dozens of drugs, such as:

  • Bambuterol, Bitolterol, Carbuterol, Fenoterol, Fenoterol, Formoterol, Hexoprenaline, Imaterol, Indacaterol, Isoetarine, Isoproterenol, Pirbuterol, Procaterol, Reproterol, Rimiterol, Salbutamol, Salmeterol, Terbutaline, Tretoquinol, Tulobuterol.

Almost all drugs from this list have the same indications, contraindications and side effects.

Some of the enlisted drugs were already withdrawn from the market and today are not available for sale.

Clenbuterol in clinical use

Clenbuterol was developed in the 70s of the last century.

Today, Clenbuterol is used for prevention and long-term treatment of chronic or acute respiratory diseases, such as:

  • Bronchial asthma.
  • Bronchial obstruction syndrome.
  • Obstructive bronchitis (with or without emphysema).

Clenbuterol is available in retail sale in the form of oral tablets, syrup, and aerosol for inhalation.

Clenbuterol-containing drugs used for the symptomatic treatment of respiratory diseases are sold under the brand names Clenasma, Monores, Novegan, Prontovent, Spiropent, Ventolase and others.

Besides the listed drugs, pharmacies sell combined drugs, which contain Clenbuterol and Ambroxol.

Just like drugs that contain Clenbuterol only, combined drugs containing both meds are used for the symptomatic treatment of pulmonary diseases.

Combined oral tablets and oral solution are sold under the brand names Mucospas, Mucospas Saft, Spasmo-Mucosolvan, Spasmo-Mucosolvan Saft and others.

This is not a full list of Clenbuterol-containing drugs.

You can get the information on what brand names for Clenbuterol you can find in your city from your treating doctor or pharmacist.


In dozens of countries, Clenbuterol is approved for the treatment of respiratory diseases in horses ONLY.

If a horse is diagnosed with acute or subacute bronchitis, it can be prescribed with Clenbuterol in the form of oral solution, oral syrup, or intravenous injections.

Horses with bronchopneumonia symptoms can be prescribed Clenbuterol in combination with antibacterial and (or) bacteriostatic drugs.

Veterinary drugs containing this active substance are available in pharmacies under the brand names Dilaterol, Equipulmin, Respipulmin, Spasmobronchal, and Ventipulmin.

It is quite possible that Clenbuterol-containing drugs for horses are sold under other brands in your region.


The drug differs from other meds for the symptomatic treatment of pulmonary diseases through the fact that it has a very high potential for abuse.

How to take Clenbuterol

Well, we are not really interested in how horses are administered Clenbuterol, are we?

It all comes down to its use in bodybuilding.

So, first you need to know that therapeutic doses of Clenbuterol will not provide a sufficient fat loss effect.

Those who use Clenbuterol hydrochloride to help alleviate the breathing disorder symptoms will not achieve the same results that bodybuilders achieve with the use of this drug.

At that, their risk for side effects is a lot lower.

However, it doesn’t mean that you immediately should start with the highest possible dose.

In fact, if you’re just starting your journey in bodybuilding “aids”, your Clen cycle dosage should not exceed 20 mcg/day.

Yes, you should be gradually upping the dose to 60-80 mcgg/day, but do it slowly and carefully note changes in your body (negative ones signal that you should stop upping the dose).

Those athletes, who are familiar with using buterol, may start their cycle with doses above 60 mcg, yet should avoid reaching doses over 200 mcg/day.

Clenbuterol dose for women is lower, starting from 10 mcg/day and reaching the top limit at 40 mcg/day.

As for the dosing regimen… you have 3 options to choose from:

  1. Start with a low dose, up it every 14 days and take it for a long time (up to 2 months, no more than 2 cycles per year);
  2. Start with a low dose, up it every 2 days until the desired dose and take it for 2 weeks altogether. Stop Clen for two weeks and then resume.
  3. Start with a dose that corresponds to your level of clen use and take it two days in a row, then stop for two days. Resume (can be used many months in a row).

It depends on you, which Clenbuterol cycle to choose. Just so you know… the first two are the most widely used, while the last has proven rather ineffective.

You can use Clenbuterol in different stacks and add drugs, which will help you reach your goals faster.

Bonus tip!

While Clenbuterol cycle does not require running a PCT (post-cycle treatment), pay attention to what you pair it with and make sure to run a proper PCT for other drugs included.

Buterol pills or?

While looking for Clenbuterol for sale, you can find pill and liquid versions.

Which to use?

No one can give a precise answer – everything depends on your own preferences.

If you don’t find it to be troublesome to count the drops to make sure that you don’t overdose – it’s fine, use liquid Clenbuterol.

If additional calculations are not your favorite pastime, and you feel better by just taking the pill, do so.

Clenbuterol effects

As already mentioned above, Clenbuterol was primarily appreciated for its decongestant and bronchodilating effects.

Clenbuterol effects


Bodybuilders appreciate it for its ability to help them lose fat, mainly as a weight loss drug.

Even though the clinical trials did not report extremely high changes in the body fat level, they have proven that Clenbuterol is capable of improving the muscle mass and the lean/fat ratio.



This same study found out that even though the maximum strength does increase on Clenbuterol, the stamina declines.

It is up to you to decide whether you are willing to give it a try, but before you make the last step, check out possible side effects of Clenbuterol.

Make sure that you know enough to make an informed decision.

Clenbuterol side effects

Abusing Clenbuterol, most sportsmen even do not suspect that this drug creates serious risks for their health.

Each athlete, who wants to use Clenbuterol as doping must be cautioned that extended use of this drug or its use in high doses:

  • Contributes to the development of hypertension and increased heart rate
  • May cause cardiac hypertrophy and necrosis of the cardiac muscle fibers.

In addition to cardiovascular side effects, Clen may cause Thyrotoxicosis, which, in turn, can seriously deteriorate your health.

When you stack Clen with any other drugs, steroids, carefully monitor your health to avoid unexpected severe side effects.

Abusing Clenbuterol


Always play it safe, no matter how much you want to obtain fast results!

Clenbuterol is illegal in the US, so you will not be able to find on the shelves of American pharmacies.

However, some European residents, as well as Chinese ones, have a great chance to find this drug in free access.

If you decide to buy Clenbuterol but this beta agonist is not sold in your city, you might decide to search for it on online pharmacies.

Be careful, opt for trustworthy stores.

Otherwise, you may end up with placebo at the best and some dangerous substances instead of Clen at the worst.

And never forget: No matter which drug you use, your persistence in diet and workouts is the key to success.
