Could someone explain to me after a cycle how cortisone is envolved and if it's high enough to cause any damage to joints/bones like osteoporosis or something like avascular necrosis. I heard about this kid at my high school 6 years ago that took some sort of steroid for his asma it might have been prednisone. But anyhow I looked it up prednisone is a form of cortisone. And my question is after taking an anobolic steroid what actually happens to the body that cortisone is envolved is it high doses and how can I reduce it.. Not sure if this is making since I just thought I read somewhere about cortisone after anobolic treatment thanks.
