GHK-Cu: Why Scientists Are Studying This Copper Peptide
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring copper-binding tripeptide that has become one of the most studied compounds in dermatological and regenerative research. First identified in human plasma in 1973, its concentration naturally declines with age — driving decades of research into its role in tissue maintenance and repair.
What Does GHK-Cu Do in Research?
Collagen Synthesis
Stimulates production of Types I and III collagen — the structural proteins responsible for skin firmness, tendon strength, and vascular integrity.
Elastin Production
Increases elastin synthesis — the protein responsible for tissue elasticity, resilience, and the ability to return to shape after stretching.
Antioxidant Defence
Upregulates superoxide dismutase (SOD) and other antioxidant enzymes, reducing oxidative stress damage at the cellular level.
Wound Healing
Preclinical models show accelerated wound closure, reduced scar formation, and enhanced angiogenesis at wound sites.
Why Does Age Matter?
GHK-Cu levels in human plasma peak around age 20 and decline steadily. By age 60, circulating levels are approximately 60% lower. This correlates with reduced collagen production, thinner skin, slower wound healing, and increased oxidative damage — the hallmarks of biological ageing.
GHK-Cu in Combination Research
Our Glow Blend combines GHK-Cu (50mg) with BPC-157 (10mg) and TB-500 (10mg). GHK-Cu drives collagen and elastin synthesis while BPC-157 and TB-500 support tissue repair through complementary angiogenic and anti-inflammatory pathways.
GHK-Cu is also available as a standalone 50mg vial for researchers who prefer to control their own ratios. For reconstitution volumes, see our Reconstitution Guide.
