I’m far from an expert on an injury like you have, in fact zero expertise in that area at all so take the following with a grain of salt as it’s all anecdotal. As this is only my personal experience.
I’ve experienced benefits from BP-157 but… I use a combo of BPC-157 + TB-500.
I take 500mcg of each every morning, for over 14 months now. 3 months ago added a 3rd to that combo, MOTS-c
All my “old” injuries have responded. An old high ankle sprain that was a chronic pain point for over a year, gone. A back injury I suffered when I was 16 (52 years ago) that was intermittent over the years and would be triggered by a sneeze or reaching over my head, just weird innocuous triggers over most of my life, maybe once or twice a year. Gone.
My wife is on the same program.
When I do hard physical labour, I often think “I’m going to pay for that”, one nights sleep and I get up with zero effects. Our last big project was cutting down a tree in our yard. It was over 50’ tall and right next to my fence and house. I had to cut it down from as high up as I could get on a 15’ ladder, taking it down branch by LARGE branch. With my wife doing the lugging and me doing the cutting, it took over 4 hours of work. Both the house and the fence survived
As a keyboard user, I had quite a few blisters LoL! Zero muscle pain the next day, just a bit tired. Joan had the same experience, no after effect from the work.
A friend has had 12 years of pain from 2 operations on her neck. A very athletic ball player who suffered significantly. She never stopped playing ball but did stop winter practise. Two months of the combo dose and she is astounded at being pain free for the first time in 12 years and back working out and doing winter ball practise that she could not do as she “saved” herself for the season so she would not be crippled up from winter practise.
I’ve got more anecdotes with friends and family on this one. A couple of them blow me away, as impressive to me as the example above.
I’m often asked why I take this every day and my answer is it helps keep me young
or at the very least, feeling young LoL! It also gives me the confidence to do hard things “a person my age” might shy away from.
