GHK is the parent tripeptide Gly-His-Lys, originally isolated from human plasma by Loren Pickart (1973) as an activity that caused aged hepatocytes to synthesize proteins like younger tissue. It is DISTINCT from GHK-Cu, the 1:1 copper(II) complex tracked as a separate entry — but GHK binds copper readily in vivo, so in physiological environments the bare peptide rapidly associates with available Cu(II). Not FDA-approved for any indication; used in cosmetic and research contexts only.

Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Every vendor on this page is verified for endotoxin testing — not just HPLC purity.
The overwhelming majority of GHK research uses the GHK-Cu complex; direct studies of copper-free GHK are limited. Pickart (J Biomater Sci Polym Ed, 2008, PMID 18644225) reviewed GHK's role in tissue remodeling and wound healing. Pickart et al. (Oxid Med Cell Longev, 2012, PMID 22666519) reviewed GHK-Cu in oxidative stress and cognitive aging. Pickart, Vasquez-Soltero & Margolina (BioMed Res Int, 2014, PMID 25302294; 'GHK and DNA: Resetting the Human Genome to Health') summarized microarray data indicating GHK modulates expression of thousands of human genes. No human clinical trials exist for injected bare GHK; cosmetic formulations typically use topical GHK or GHK-Cu at ~50–200 ppm.
