Generally a Clenbuterol cycles will last around 6 weeks at 2 weeks on 2 weeks off, it is often also used along with T3 (thyroid hormone) and an Anabolic such as winstrol, test prop and trenbolone . Incorporating Anabolic Steroids into a clenbuterol cycle will lead to much better results.
Is there anything to worry about?
Yes there is. In fact, if you abuse the use of fat burners then there is certainly a lot to be worried about. You would be preparing yourself for side-effects which could be short-term, long-term, reversible or irreversible. Sounds horrifying? It is intended to be so because unless you use these things under proper guidance of an expert or medical practitioner, you are making a good case of what not to do. There have been cases in the past when people go to extremes in their desperation and suffer from side-effects. It is generally not the product that has to be blamed but the greed of the user for overnight success.
