In the world of bodybuilding, staying fit and maintaining muscle are some of the largest parts of the sport. With things like the International Federation of Bodybuilding and Fitness Mr. Olympia competition looming over competitors heads, keeping in shape is even more important. When you need the extra boost to obtain and maintain weight loss and muscle gain, Clenbuterol comes into play.

What is Clenbuterol?

Clenbuterol is a sympathomimetic amine, this means that it is compound considered to be a stimulant that mimics the effects of endogenous agonists of the sympathetic nervous system and it belongs to a class of drugs known as beta2-agonists.

The sympathetic nervous system (SNS), stimulates the body’s fight or flight response. Beta2-agonists are a group of drugs that treat asthma with an added benefit of potentially preventing exercise induced bronchoconstriction. This type of constriction is a constriction of the airways from the tightening of surrounding smooth muscles. This tends to result in coughing, wheezing, and shortness of breath.

Because of its abilities to help with these situations, Clenbuterol’s primarily use is as a decongestant and bronchodilator. This makes it easier for the person using Clenbuterol to breath. However, it has shown an affinity to also aid with weight loss, as well as having similar effects to ephedrine. Clenbuterol has also gained popularity due to its abilities to aid with muscle gain and fat reduction. Something to keep in mind is that although many believe it to have anabolic properties, Clenbuterol is not a steroid.


Several studies conclude the effectiveness of Clenbuterol for asthma, muscle growth and more. Many of these studies use animal models as a precursor to human trials.

In one study, horses were the subjects. Clenbuterol is a good therapeutic treatment for respiratory conditions in horses according to some findings. In addition to this, scientists discovered another less common side effect. Clenbuterol was able to decrease the percentage of fat in these horses while increasing fat free mass when subjected to a higher dose of Clenbuterol and intense exercise.

Another study used rats to test the effectiveness of Clenbuterol in accelerating recovery after cast immobilization induced atrophy. Twenty four Sprague Dawley rats were divided into four groups of six and given five days to adapt to their new surroundings. The groups include a control, casted immobilization following recovery control, casted immobilization following recovery with Clenbuterol, and casted immobilization. The group labeled as casted immobilization following recovery with Clenbuterol a dose of 1mg/kg based on body weight was given daily through subcutaneous injection. This administration occurred over a two week span. Clenbuterol is able to accelerate the recovery of atrophied plantaris and soleus muscles, according to the findings.

In a study done with tilapia, Clenbuterol was tested to see if it was effective in modifying gene expression in lipid metabolism and skeletal muscle. During the study, the fish were divided into three groups that consisted of a control group as well as a group administered 5ppm/kg and 10ppm/kg of Clenbuterol. This was completed over the course of thirty days. The results of the research were promising. Body weight of the tilapia was increased with a decrease in liver, spleen, and abdominal fat weight. It also managed to decrease the total circulatory and triacylglycerol levels.

Benefits and Side Effects of Clenbuterol

Over the course of its existence, Clenbuterol has shown an affinity to not only aid with bronchoconstriction it has also shown an ability to aid with increases in muscle mass as well as reduce body fat. Another added bonus is that Clenbuterol stays active within the body for roughly six days after a dose.

Keep in mind that as long as you stay within the recommended dose range, you’re less likely to experience side effects. However, side effects while using Clenbuterol can occur. Some of these side effects include things like tremors, anxiety, an imbalance in electrolytes, increased heart rates and rapid breathing. Some less common side effects include things like heart palpitations and chest pain. Consult your doctor if these side effects occur.

Clenbuterol Dosage

There are two common ways that Clenbuterol is available. The first is as a tablet and the second through an inhaler. Just as there is two forms of this substance, there are also two dosing protocols. One is for Clenbuterol’s use as an asthma treatment and the second is for weight loss and muscle gains. Since there is a significant difference it is important to know the two variations.

For the purpose of using Clenbuterol for asthma related symptoms, the common dose is around 0.02mg to 0.03mg per day. This dose is typically dependant on the severity of your asthma symptoms. Many recommend taking it as needed.

When it comes to using Clenbuterol for muscle gains and weight loss there are three variations available as either a tablet, liquid, or injection. A dose for weight loss or muscle gain is between 0.06mg and 0.12mg per day.

Even if you are training hard, eating right, and doing everything in your power to get into shape, you still may need the extra boost that only Clenbuterol can give.
