Copper Peptide

A naturally occurring tripeptide (Gly-His-Lys) that binds copper. Topical studies show wound healing and collagen stimulation in skin — but these are topical application, not oral supplementation. Gene expression studies (Pickart et al.) show broad anti-inflammatory and tissue-remodeling signatures in vitro. Zero human RCTs for oral supplementation exist. Oral bioavailability of the intact peptide is unknown — likely degraded by gastric proteases. Popular in anti-aging biohacking communities.
