Clenbuterol
A long-acting beta-2 agonist used off-label as a thermogenic fat-loss agent. It raises metabolic rate but stresses the cardiovascular system.
- Half-life
- 1.5 d
- Out of system
- ~8 days
- Route
- Oral
- Level
- Intermediate
Levels carry over between doses — every 2–3 days is typical. After the last dose, roughly 97% has cleared in ~8 days (five half-lives) — the window that matters for washouts, bloodwork and surgery.
What Clenbuterol is used for
- Raises metabolic rate and body temperature to promote fat loss
- May help preserve muscle while dieting in a calorie deficit
- Also acts as a bronchodilator
How it's typically used
Anecdotal user reports describe roughly 40-120 mcg daily titrated slowly, framed as reported practice and not a recommendation.
What to watch for
- Causes tremor, muscle cramps, insomnia, and a racing heart
- Places real strain on the heart and can cause dangerous tachycardia
- Long half-life makes it easy to stack the dose too high
- Not FDA-approved for human use in the US; used off-label with real risk
