Partial Chest Tear Recovery

Wondering if anyone has recovered from a partial chest tear. I tore my pec major last year but still suffer from pain in the shoulder whilst weight training and bjj and tips to help with recovery

I had a partial tear of my right pec about a year and a half ago. It about the center of the bottom edge, just in the muscle. A fairly noticeable gap formed. My doctors would only say rest and heal.

I used BPC-157 3 times per week in the affected area. It was completely healed after about 3 months. No sign there was ever a problem, and fully functional.
