GHK-Cu and Brain Health: Cognitive Aging Research Update

GHK-Cu shows potential for supporting cognitive health during aging through multiple protective mechanisms.

What Is GHK-Cu?

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper tripeptide found in human plasma, saliva, and urine. It declines with age, dropping by about 60% from age 20 to 60. GHK-Cu stimulates collagen and elastin production, promotes wound healing, and has anti-inflammatory effects.

It's one of the most versatile peptides, with applications in skin care, wound healing, hair growth, and tissue repair.

Dosing and Applications

GHK-Cu can be used topically (skin serums, gels), subcutaneously (injection), or in combination with other peptides. Injectable doses typically range from 1-2 mg daily. Topical concentrations of 3-5% are common in skin care. Use our GHK-Cu dosage calculator for injection protocols.

Evidence Base

GHK-Cu has extensive published research, including the landmark gene expression study showing it modulates over 4,000 human genes. The Phase 2 wound healing trial adds clinical evidence to the preclinical body of work.
