Yeah, it is no panacea for sure. For me, I have been lifting for years, doing BJJ for years. Ran for almost two decades. I consider myself in pretty good shape for a random dude on the street. It all takes work. Especially with Rehab you really have to put in the rehab work to direct the healing and if you went with pharmaceuticals like we are discussing that becomes extra important. But I think at low, therapeutic dosage it is all really safe. On a 3 month cycle during injury recovery you are unlikely to grow muscle quickly enough to do any real damage either.
