I also have a SLAP tear and would love to use BPC or something else to fix it, as I'm not going to have surgery. However, injecting a grey market research chemical I bought off the Internet into my body is just way, way outside my risk tolerance. I could I guess imagine imbibing a pill or powder..... direct injection when you don't really know what it is, it's not from a regulated supplier- just seems nuts to me, no offense
