GHK-Cu — the copper-bound tripeptide Glycyl-L-Histidyl-L-Lysine — is the most-studied research peptide in dermal-signaling and tissue-repair literature, with over 100 peer-reviewed publications since its 1973 discovery. BioInfinity Lab ships research-grade GHK-Cu at ≥99% HPLC purity, third-party COA, same-day from New York.

GHK-Cu was first identified by Loren Pickart in 1973 as a small bioactive peptide-copper complex isolated from human plasma. The compound's age (50+ years of research literature) and unusual mechanism — a tripeptide that binds copper(II) at physiologically relevant affinity and modulates copper-dependent enzymes — makes it one of the most-cited research peptides in dermal-research and tissue-repair literature.
Pickart's 2015 review in Biomed Res Int (PMID 25387478) is the most-cited modern entry point — it characterizes GHK as a natural modulator of multiple cellular pathways. Earlier publications including 2011 work in Cell Mol Biol (PMID 21982685) cover copper-peptide research in dermal-cell research models, and the 2017 Cosmetics paper (PMID 28443327) reviews tissue-repair signaling research.
Research literature describes the copper-bound complex (GHK-Cu) and the uncomplexed tripeptide (GHK) as functionally distinct. The copper-bound form is the one most commonly cited in dermal-research and tissue-repair literature because of its activity at copper-dependent enzymes. Researchers replicating published GHK-Cu work should source the copper-bound complex specifically — not the unconjugated tripeptide.
BioInfinity Lab supplies lyophilized GHK-Cu in 50 mg and 100 mg vials. Store lyophilized at −20 °C protected from light; reconstituted at 2–8 °C and used within 30 days per laboratory SOP. For researchers running combined dermal-research protocols, see also our [Glow Blend research vial](/buy/glow-blend) which centers on GHK-Cu alongside complementary tripeptides.
