Peptx supplies GHK-Cu, the copper-binding tripeptide-1 with one of the deepest published literatures of any cosmetic and tissue-remodelling peptide. Typically 99%+ purity (HPLC), lyophilised vials in multiple vial sizes, factory-direct pricing, tracked worldwide shipping.
About GHK-Cu as a research compound
GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) first isolated from human plasma in the 1970s. Endogenous GHK-Cu concentrations decline sharply with age, which is why the synthetic form has become one of the most extensively studied peptides in the dermatology and regenerative-research literature.
Published research covers wound healing models, collagen and elastin synthesis assays, anti-oxidant and anti-inflammatory cell studies, hair follicle research, and gene-expression work. GHK-Cu has been shown in transcriptomic studies to modulate the expression of more than 4,000 human genes, making it a uniquely well-characterised reference compound for tissue-remodelling research.
All GHK-Cu vials ship as lyophilised powder with the characteristic blue tint from the copper-binding complex. Reconstitution with bacteriostatic water yields a stable solution that should be refrigerated at 2 to 8 Celsius.
Why research labs buy GHK-CU from Peptx
Factory-direct sourcing
Peptx sources directly from manufacturers cross-referenced against independent lab testing. No middlemen and no compounding-pharmacy markups; just the factory price plus a small fixed margin.
Purity and testing
Peptx material is typically 99%+ purity (HPLC). Recent independent laboratory results are published in the COA Library. Certificates are not shipped with orders. You are welcome to send a sample to an accredited lab yourself; a 14-day refund window applies to any independently verified result below the product's stated guaranteed minimum purity.
