For many men, the real risk of gynecomastia occurs once the steroid cycle has ended. This is because anabolic steroids suppress the male body’s ability to produce testosterone on its own. Without the use of medications to help facilitate that steroid production, the estrogen-to-testosterone ratio becomes too high, and gynecomastia may result. Following a cycle with AAS, it is vital to use a medication called a SERM, or Selective Estrogen Receptor Modulator, like Nolvadex or Clomid. These medications help to ensure that the body gets just the right amount of estrogen – not too much or too little. These medications will also help to facilitate testosterone production, thereby reliving some of the risk, as well.
