Stanozolol tablets have a short life time about 9 hours as compared against injectable stanozolol, it has unusual pharmacokinetics which do not follow the classic half-life pattern. Instead, there is a sustained effect which slowly tapers. The duration of action is probably at least a week.

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.

To summarize, stanozolol is generally recommended for athletes having sufficient muscle bulk, but wishing to improve endurance and increase muscle relief and hardness.
