Does BPC-157 help with muscle growth?
No muscle-growth result in people is cited here; the muscle data are from a rat study of injured muscle, which tested healing, not size or strength gain.
Gastric pentadecapeptideUpdated
Short answer
No muscle-growth result in people is cited here; the muscle data are from a rat study of injured muscle, which tested healing, not size or strength gain.[1]
The injury model in that rat study was a crushed gastrocnemius muscle complex, with the peptide given by injection or as a cream.[1]
What reviews say about muscle
A systematic review summarised the preclinical muscle findings as improved outcomes in injured muscle among other tissues, again describing injury models.[2]
The only clinical study that review identified looked at knee pain relief, not at muscle mass or strength.[2]
