So, if you have the money, instead of getting a second or a third anabolic steroid to stack during your cycle, take that money and invest in an anti-estrogen. I have also noticed that when an anti-estrogen is taken, the gains seem to be bigger during a cycle, because you don't have the estrogen limiting the effects of the testosterone. Also, I found it best to give a 6-8 week break between cycles to give your body a rest and a chance to get back to normal. As long as you keep lifting, you shouldn't lose too much of your gains, but don't get pissed if you can't bench what you did in the peak of your cycle. Gynecomastia is a common side effect of anabolic steroid use.
Men naturally produces a small amount of estrogen, a female hormone.
When anabolic steroids are used estrogen levels can rise and or dominate. Some anabolic steroids are peripherally converted to estrogen. When these steroids are used both anabolic hormone and estrogen levels rise. High estrogen levels will sooner or later cause gynecomastia in most individuals. Abruptly stopping steroid use greatly increases the odds of developing gynecomastia.
