Description

Clenbuterol is a drug that was originally developed to treat asthma and other respiratory diseases due to its bronchodilator properties. However, over time it has found use in bodybuilding and sports due to its fat burning and performance enhancing properties.
Mechanism of action

Clenbuterol is a beta-2 agonist, meaning it stimulates beta-2 adrenergic receptors in the body. Its effects include:

Bronchodilation: Improves airflow into the lungs, which originally made it an effective asthma treatment.
Increased thermogenesis: Raises body temperature by stimulating the nervous system, leading to increased calorie burning and fat reduction.
Increased metabolism: Speeds up metabolism which helps in weight loss.
Anti-catabolic effect: In bodybuilding it is also valued for its anti-catabolic properties, i.e. its ability to protect muscle mass during a reducing diet.

Application in bodybuilding

In bodybuilding, Clenbuterol is mainly used as a means of supporting the reduction of body fat and improving muscle definition. Its advantages include:

Fat Burning: Helps reduce fat, which is especially desirable during periods of competition preparation.
Increased Performance: Improves performance and endurance, allowing for more intense workouts.
Muscle Protection: Helps preserve muscle mass during a calorie-restricted diet.

Dosage

Clenbuterol dosage in bodybuilding is individual and depends on many factors, such as user experience, purpose of use and body tolerance. Example dosage regimens may look like this:

Beginner: Start with small doses, e.g. 20-40 mcg per day, gradually increasing to 80-100 mcg per day.
Advanced: May use higher doses, e.g. 120-160 mcg per day, but always with caution.

Application Cycles

2-Week Cycles: The most common regimen is 2 weeks on Clenbuterol, followed by a 2-week break. This is repeated several times.
Continuous use with ketotifen: Some athletes use Clenbuterol in longer cycles, using ketotifen (an antihistamine) to prevent receptor adaptation.

Possible side effects

Clenbuterol can cause a number of side effects, including:

Hand shaking
Nervousness and anxiety
Headaches
Excessive sweating
Sleep disorders
Muscle cramps
Increased blood pressure and heart rate

Monitoring: Clenbuterol use should always be monitored by a sports medicine specialist or sports dietitian.
Interactions: May interact with other medications, so consult your doctor before use.
