Ya. And it's probably worth pointing out that in the context of a recovery (say after a cast) that taking steriods and/or HGH will still require physical rehab, with even more doctor supervision. While it would probably lower the median time to "full recovery", it would probably also have significantly worse worst case outcomes, and still require significant work from the patient.

Edit: Oh and specifically for steroids - one of the things that -can- (dunno how frequent really) happen is that your muscle strength growth outgrows your connective tissue (such as your Achilles tendon) growth rate and you end up with more connective tissue damage. Maxing out your muscle growth rate might be the best strategy, especially when recovering from connective tissue damage.

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.

Look into BPC-157.
