There are some side effects with use, most of which are related to the increase in endogenous test’ levels to which it promotes. Acne, gynaecomastia, and increased hair growth are possible (as with many androgenic steroids), but in many cases levels will not get high enough to be problematic. Other effects may include headaches, irritability, mental depression, and tiredness (. all the signs of female pregnancy in the first trimester), but these are even less common. should never be used by anyone with enlargement/cancer of the prostate or pituitary gland, but since it is normally applied after a steroid cycle, they should definitely not be taking steroids either.
