I am thinking about going on steroids but one of the side effects I am really concerned about is breast developement. Does anyone know how common that actually is? And will any estrogen blocker take care of it? Any advice would be apreciated.
Look up the terms selective estrogen receptor modulator, aromatase inhibitor, and gynecomastia, that should get you started.
Gynecomastia is quite common with steroid, as well as in adolescents.
