[Lab] three BPC vials, three vendors, purity all over the place

Labbranch of 6 comments

Short version of the title, which is already short: three BPC vials, three vendors, purity all over the place. Longer version underneath. Ask for the theoretical mass alongside the measured one. It is a one-line addition to a certificate and it converts a purity claim into an identity claim. Research-use-only…

About c/bpc157

BPC-157 as it actually is: a pentadecapeptide with a genuinely interesting rodent tendon-and-gut literature, near-zero controlled human data, a naming and sequence mess in the supply chain, and a regulatory status that changed sharply in several countries.
