Clenbuterol in Bodybuilding: What It Is, How It Works & Key Info

What Is Clenbuterol?

Clenbuterol (commonly called “Clen”) is a beta-2 adrenergic agonist, originally developed as a bronchodilator for asthma. It’s not approved for human medical use in the United States, though it is prescribed in some countries for respiratory conditions.

In bodybuilding and fitness circles, clenbuterol gained popularity as a fat-loss drug, not a muscle-building compound. It is not an anabolic steroid, though it is frequently discussed alongside them.

How Clenbuterol Works

Clenbuterol stimulates beta-2 receptors in the body, leading to:

• Increased metabolic rate

• Higher body temperature (thermogenesis)

• Enhanced lipolysis (fat breakdown)

• Appetite suppression

• Central nervous system stimulation

Athletes use it primarily during cutting phases, not bulking. It does not build muscle mass—its role is preserving lean tissue while reducing fat, when combined with diet and training.

Why Bodybuilders Use It

Although risky, users pursue clenbuterol for:

✅ Fat loss while maintaining muscle
✅ Increased energy for training
✅ Enhanced lean, “dry” physique look

But these potential benefits must be weighed against serious health risks.

⚠️ Health Risks & Side Effects

Clenbuterol affects the cardiovascular and nervous systems. Reported risks include:
