GHK-Cu — the copper-bound tripeptide Glycyl-L-Histidyl-L-Lysine — is the most-studied research peptide in dermal-signaling and cellular-pathway literature, with over 100 peer-reviewed publications since its 1973 discovery. BioInfinity 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 cellular-pathway 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 cellular-pathway 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 cellular-pathway 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 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.
All GHK-Cu orders ship same-day from our New York facility on orders placed before 2 PM ET, Monday through Friday. Free shipping on orders over $200; every lot ships with a batch-specific Janoshik Analytical Certificate of Analysis referenced on the product page.

I was skeptical about ordering online, but product shipped quickly, very well packaged, and the quality seems top tier. Communication was great. Will be using them again for future purchases.
Great customer service, great product and speedy delivery!
Easy reconstitution, excellent quality and purity.
After taking GHK-Cu at the recommended dosage for a couple of months, I honestly didn’t notice any significant difference overall. I didn’t experience any negative side effects or adverse reactions, which was a positive, but I also didn’t see or feel any noticeable improvements. Everyone’s experience may be different, but for me, the results were minimal, and I was left somewhat disappointed after using it consistently for several months.
