Clenbuterol (Clen)
Clenbuterol Hydrochloride, commonly known as Clen, is a sympathomimetic amine. It is not an anabolic steroid; it is a Beta-2 Agonist. Originally developed to treat asthma (as a bronchodilator), it is widely used in bodybuilding for its potent fat-burning properties.
How It Works: Thermogenesis
Clenbuterol works by stimulating the beta-2 receptors in the body, which results in two primary effects:
Thermogenesis: It slightly increases the core body temperature. To maintain this higher temperature, the body burns calories at a faster rate.
Lipolysis: It stimulates the breakdown of stored fat (triglycerides) into free fatty acids to be used as fuel.
Bronchodilation: It opens the airways, increasing oxygen transportation and cardiovascular endurance.
Common Brand Names
Spiropent (Human grade)
Ventipulmin (Veterinary grade - syrup/liquid)
Astralean (Generic)
General Dosage Guidelines
CRITICAL NOTE: Clenbuterol is measured in Micrograms (mcg), not Milligrams (mg). Confusing these units is dangerous.
1 tablet is typically 40 mcg (0.04 mg) or sometimes 20 mcg.
Because the body adapts to Clenbuterol quickly (receptors get saturated), the standard usage protocol is the "2 Weeks On / 2 Weeks Off" method, or using it continuously with Ketotifen (to clean receptors).
The 2-Week Rotation Protocol
The goal is to slowly ramp up the dose until a "tolerable" maximum is reached, hold it, and then stop to let receptors recover.
Men (Target Max: 100 - 140 mcg)
Day 1-3: 40 mcg (1 tablet)
Day 4-6: 60 mcg
Day 7-9: 80 mcg
Day 10-12: 100 mcg

Side Effect Management
The "Shakes": Hand tremors are the most common side effect and usually indicate the drug is working.
Cramping: Clenbuterol depletes Taurine in the liver. Users usually supplement with 3g-5g of Taurine daily to prevent painful muscle cramps.
Important Safety Note
Warning: Clenbuterol is a stimulant that directly affects the heart.
Heart Rate: It will increase resting heart rate. It should not be used by anyone with cardiac issues or high blood pressure.
Insomnia: Due to its long half-life (~36 hours), taking it late in the day will cause severe sleeplessness. It should be taken first thing in the morning.
