I've used quite a bit of BPC-157, originally for hoping it would help my chronic shoulder problems, and most recently for hoping it would help tendon and ligament repair after a really bad wrenching of the foot that broke the fibula just above the ankle.
A side benefit for something that I hadn't intended to treat was that I'd developed a problem of deep cracking of the skin at the heels, which nothing would solve.
BPC-157 healed the feet, and also healed the chronic tendinitis in one of my forearms, which TB-500 never had though it helped it markedly.
It's possible that BPC-157 helped the tendinosis in the bicipital groove, but I'm not dead positive on that.
On the ankle, there's just way to know what the healing would have been without the BPC-157, so it's impossible to say. I also used TB-500 concurrently.
That it's biologically very active at doses such as about 350 mcg/day, which is what I used, there was no doubt.
If I had had the surgery that you did, personally I would use it. I hope you get good results!
