I used BPC-157 with TB500. I stopped the TB after a week because I read studies indicating it could promote cancer. I don't remember where I found them but there are quite a few on the internet that are peer-reviewed in nature. In 4 weeks, taking BPC 157 (site specific injection) seemed to heal me. This was about 6 months ago. I went to the doctor and told him my shoulder/pec symptoms and he diagnosed a subscapularis tear but cautioned to wait for the results of the MRI. I had some "subluxation" of the rotator cuff according to the specialist that performed the MRI, requiring surgery. What pissed me off is that I explained to the initial doctor that I had a small bruise at the top of my arm that expanded after a few days. This indicated a pec tear as the insertion is at the upper arm. The initial doctor never ordered an MRI on that spot but the specialist said it sounded more like a pec tear. Regardless, I took the BPC-157 and sure enough after 4-6 weeks I could Dumbbell Bench Press 125s for reps, which was almost where I was at prior to the occurrence. I honestly forget what the dosage protocol was but I alternated sites. I did medial delt, Upper pec, and upper bicep. There are some who say a simple sub-q injection will suffice but others have stated cite-specific is the way to go. It really doesn't matter either way in regards to convenience so I just injected into the aforementioned spaces. I was also on a MOD GRF 1-29/GHRP-2 cycle.
