I have considered both. I am a big believer in BPC 157. I actually still have an old bottle of it in powdered form from 4 years ago. Not sure if it’s still good now though? The MK677 doesn’t interest me anymore.
The right shoulder is an old injury at this point. It has bothered me for roughly 7 years. I have already had an arthroscopy procedure done on it 4 years ago. The surgeon shaved off the bone spur protruding off the humerus head that was constantly damaging soft tissue anytime I moved it. He also cut the clavicle to open up more space to prevent further impingement. I have better ROM since the procedure and the pain is no longer constant. My shoulder is still weak and I get pain flair ups from time to time when I push myself in the gym. It is frustrating to say the least, but I am thankful I am out of the constant pain and I can still hit the gym. Kratom cuts the pain for me and takes the edge off it so I can continue about my day.
