Scientists haven't done proper human tests to see if certain peptide supplements like BPC-157, Ipamorelin, or CJC-1295 actually help with recovery, sleep, or body composition.

This study is about BPC-157 but it's not a human randomized controlled trial - it's a reply letter discussing the peptide's mechanisms. The claim says such human trials don't exist for these peptides, and this study doesn't provide one, so it supports rather than contradicts the claim.
