Labrum Recovery Question

Just got labrum surgery, starting to learn more about the benefits of BPC 157. I’m not afraid on on-site pinning or anything like that, I will do what I need to in order to fix this shoulder as best I can. Can someone explain the best stack / dosages / timeline to take and use it for? I’ve heard good things about stacking with TB500. Also as the best source online to order the stuff from a reputable lab? I really just want a good general overview for recovery concerning mobility and strength building in my shoulder; point me in the right direction.
