The frag with bpc 157 was supposed to be called the wolverine stack, but it didn't work for me. The peptides were supposed to help with regeneration and helping with torn ligaments and muscle. After having distal bicep surgery and finished the peptides progress is really slow still. I thought the peptides would have helped a bit better but no. Unless they offer a complimentary dose to try again I don't think I would spend the $280.
