re: So, any of you ever use deer antler velvet spray for tendinitis?

Hard to say because I used both for a major pectoral muscle tear last year and I did recover much much much faster than the previous three times (over 20 year span) and I am older. Once you tear a muscle the propensity to tear it again is greater and I am a testament to that. I never had it roll complelty off the bone, but it was nasty and hurt. So, to answer your question, i really feel like for the muscle tear the BPC injected right near the point of injury was a better choice based on me talking with several fellow powerlifters and doing my own research. Use bbth if you are injured and can afford it, as they are not that pricey.
