GHK-Cu is the copper peptide most of the published skin literature is built on, and it anchors this group along with the blends that include it. Everything here is supplied as a research compound for laboratory use only, and Merit publishes no claim about cosmetic or physiological effect.

The certificate for each batch states identity and purity as the laboratory measured them. That is the part worth checking, because copper peptides are among the most commonly misrepresented materials in this market.
