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.
As for bodybuilders, Stanozolol has one interesting peculiarity demanded among them. It consists in the profound ability to lower sex hormone-binding globulin (SHBG) level resulting in efficiency growing of other steroids in stack with it. In particular, it raises the amount of biologically active free testosterone circulating in the blood. For this reason it is advisable always to use Stanozolol in stack with testosterone. Another one reason for this is as follows: Winstrol may be more prone than other anabolic steroids to increasing tendon brittleness. This happens due to Winstrol`s possibility to dry out the joint fluid, which can lead to joint pain and damages. Also both Stanozolol forms: tablets and injections have been noted to provoke adverse changes in cholesterol levels. Hence, monitoring of the lipid profile of the body (blood works) during cycle is advisable.
