Oxandolone for collagen synthesis

Ok so I have been reading but cannot find any real backed up info on it. I have a torn hamstring, a small tear in my infrasprinatus and bad tendinitis in my biceps tendon. I need to get back to 100% ASAP as I play baseball and have scouts looking at me.
I am currently taking ghrp-6 at a 'rehab' dosage but have been reading about vars effects on collagen synthesis. Does var increase collagen production, if so at what dosage for a 95kg male? And will this help with my torn hamstring and shoulder issues?

Any help muchly appreciated but pls no bullshit
