There are possible side effects of Anavar, but with confidence we can call this one of the most side effect friendly anabolic steroids of all time. In fact, with proper use many adults will be able to supplement without the first problem. To get the ball rolling, estrogenic side effects are impossible with this steroid as it does not aromatize. This makes water retention and gynecomastia impossible with Anavar. It also means blood pressure will more than likely be controlled as heavy excess water retention is the number one cause of high blood pressure among anabolic steroid users.
Serum testosterone, SHBG (Sex Hormone Binding Globulin), and LH (Leutinizing Hormone) will be slightly suppressed with low doses of Anavar, but less than with other compounds. FSH (Follicle Stimulating Hormone) , IGF1 (Insulin Like Growth Factor 1) and GH (Growth Hormone) will not be suppressed with a low dose of Anavar, but will actually be raised significantly (12)(13)(14) as you may have guessed, and LH will even experience a “rebound” effect when you stop using anavar (3) If your endocrine system and HPTA are funtioning normally, you should be able to use anavar with minimal insult to it, and can even keep most of your values within the normal range (5).
