Clenbuterol – Dosing and Cycling

Last updated on September 6th, 2023 at 10:49 am

Clenbuterol is not approved for human use in many countries, including the United States, and is primarily intended as a bronchodilator for animals. However, it has been misused by some individuals, including athletes and bodybuilders, for its potential thermogenic and lipolytic effects, which may aid in weight loss and fat burning. It is crucial to emphasize that using Clenbuterol for weight loss or bodybuilding purposes without proper medical supervision is not recommended due to its potential health risks and side effects.

That said, for informational purposes only, here is some general information about Clenbuterol dosing and cycling that has been used by some individuals who misuse the drug:


  • Clenbuterol is typically taken orally in tablet or liquid form.
  • The dosing pattern often involves starting at a low dose and gradually increasing it over several days.
  • A common dosing cycle is a two-week “on” and two-week “off” pattern.

Example of a Clenbuterol dosing cycle for misuse (Note: Not recommended):

  • Day 1: Start with 20 mcg per day
  • Day 2: Increase to 40 mcg per day
  • Day 3: Increase to 60 mcg per day
  • Day 4: Increase to 80 mcg per day
  • Day 5-14: Maintain at 80 mcg per day
  • Day 15-28: Discontinue Clenbuterol (off period)


  • The cycling pattern aims to prevent the body from becoming tolerant to Clenbuterol’s effects and to reduce the risk of adverse reactions.
  • Some individuals cycle Clenbuterol with other substances, including anabolic steroids.

It is essential to reiterate that the use of Clenbuterol for weight loss or bodybuilding without proper medical supervision is dangerous and illegal in many regions. Misuse of Clenbuterol can lead to serious side effects, including increased heart rate, tremors, nervousness, high blood pressure, and even cardiac complications.

For individuals seeking to achieve weight loss or muscle development, it is crucial to prioritize safe and evidence-based methods, such as proper nutrition, regular exercise, and guidance from qualified healthcare professionals or fitness experts. There are legal and healthy alternatives to Clenbuterol for achieving fitness goals, and individuals should always prioritize their health and well-being over shortcuts or risky practices.
