Overview
GHK-Cu is a naturally occurring copper-binding tripeptide complex (Gly-His-Lys) found in human plasma, urine, and saliva. Its serum concentration declines significantly with age — from approximately 200 ng/mL at age 20 to under 80 ng/mL by age 60 — which has driven sustained research interest in its regenerative and anti-aging properties.
Research Context
GHK-Cu has one of the most extensive research profiles of any peptide in the Biohacker catalogue, with over 50 years of published study. Documented biological activities include stimulation of collagen, elastin, and glycosaminoglycan synthesis; promotion of wound healing and skin remodelling; anti-inflammatory effects through modulation of TGF-beta and TNF-alpha; antioxidant activity; and neuroprotective mechanisms. Gene expression studies have identified GHK-Cu as a regulator of over 4,000 human genes, including those involved in inflammation, tissue remodelling, and longevity pathways. It has been studied in dermatological, neurological, and oncostatic contexts.
Oral Capsule Format
As a tripeptide-metal complex, GHK-Cu presents specific stability and absorption considerations. Biohacker’s formulation preserves the copper chelation complex through the gastrointestinal environment via enteric encapsulation, releasing the intact complex at intestinal pH for absorption.
10mg per capsule · 60 capsules per bottle. Every batch independently tested for purity, mass confirmation, and endotoxin compliance. Certificate of Analysis available for each lot.

GHK-Cu at 99.6{bc6192475b1f7ab2a319df0d74882f1947535342342376b459ce77de5d749ac5} purity is exceptional. The copper chelation complex is intact — I verified the absorption spectrum before use. Biohacker is the only oral source I’ve found with this level of purity documentation. Will remain my primary source.
