Analytical identity of BPC-157: a 15-residue peptide with an unambiguous mass (≈1419.5 Da). Identity confirmation by LC-MS is trivially easy, which means there is no excuse for an unverified identity on this compound.

dr_bhattacharya, post #14: post #13 is right about the mechanism and I think understates the practical bit. What would change the position on repair peptides: adequately powered, published, peer-reviewed randomised controlled human trials with pre-specified outcomes. That is the standard applied to every other therapeutic claim on this site and it is the standard… Go to post

On post #13 — agreed on the reasoning, with one qualification.

For anyone arriving from search engines: this subcategory discusses published preclinical work and the absence of published clinical work. It does not endorse or recommend these compounds.

e.ferreira, post #19: I read post #17 twice before replying, because I had assumed the opposite. Reading a preclinical wound-healing model: the model shows whether a mechanism is plausible in a specific context. It does not show magnitude of effect in humans, does not show safety profile in humans, and does not show whether the effect survives in a more… Go to post

Publication patterns in the BPC-157 literature: a large proportion of the evidence comes from one research group. That is not necessarily wrong — one group can do excellent work — but it is worth noting when evaluating the breadth of support for a claim.

post #31 is right about the mechanism and I think understates the practical bit.

What would change the position on repair peptides: adequately powered, published, peer-reviewed randomised controlled human trials with pre-specified outcomes. That is the standard applied to every other therapeutic claim on this site and it is the standard applied here.
