Active Substance: Copper peptide GHK-Cu
Pack: 1 Vial x 5 mg
GHK-Cu is a small, naturally occurring tripeptide (1$text$) that is chemically bound to a copper ion (2$text2+$).3 It acts as a crucial signaling molecule found in human plasma, saliva, and urine, where it is released as an emergency response molecule to accelerate tissue repair.4
GHK-Cu levels naturally decrease significantly with age, correlating with slower wound healing and visible signs of aging.5
GHK-Cu's efficacy stems from its multi-pronged action, often referred to as "cosmetic tissue repair":6
Collagen and Elastin Production: GHK-Cu acts as a signaling molecule to activate fibroblasts for intensive production of Type I and Type III collagen and elastin.7 This action dramatically improves skin firmness, elasticity, and density, thereby minimizing the appearance of fine lines and wrinkles.
Accelerated Healing and Anti-Scarring: The peptide enhances all phases of the healing process (inflammatory, proliferative, and remodeling).8 It promotes organized collagen deposition rather than the random arrangement typical of scar tissue, helping repair more closely resemble normal skin architecture.
Gene Modulation: Research suggests GHK-Cu can influence over 4,000 genes, effectively resetting the gene expression profile of aged skin cells to patterns similar to younger cells.9
Antioxidant and Anti-Inflammatory: GHK-Cu neutralizes free radicals and reduces inflammatory markers in skin tissue, offering protection against oxidative damage that accelerates aging.10
GHK-Cu is primarily used in topical formulations for skin rejuvenation.11
Administration Route: Typically applied in topical preparations (creams, serums) to clean skin.12 Enhanced penetration can be achieved through gentle exfoliation or microneedling beforehand.13
Dosage: For topical preparations, concentrations often range from 14$0.1%$ to 15$2.0%$ GHK-Cu.16 Consistent application every day for at least 8–12 weeks is required to achieve full structural benefits.17
Timing: It is often recommended for evening application to leverage its collagen-stimulating properties during the night.18
Avoid applying GHK-Cu simultaneously with Vitamin C ($text$-Ascorbic Acid). Copper peptides can oxidize Vitamin C, negating its antioxidant benefits.19 It is best to use GHK-Cu in the evening and Vitamin C in the morning.
The copper ion ($text2+$) is essential for the peptide's function. The GHK tripeptide acts as a carrier peptide, binding the copper and delivering it into cells.20 Copper is a critical cofactor for enzymes (like lysyl oxidase) necessary for the cross-linking of collagen and elastin fibers, ensuring they form strong, durable networks for wound healing and structure.21
No. GHK-Cu is strictly a regenerative and anti-aging compound focused on tissue health and skin aesthetics. It has no immediate or direct use for increasing muscle growth or strength. Peptides used for muscle/tendon performance are typically BPC-157 or TB-500.22
Yes. GHK-Cu enhances wound healing and promotes the repair process by stimulating organized collagen deposition, which helps the repaired tissue more closely resemble normal skin architecture, thus contributing to anti-scarring effects.23
GHK-Cu has a highly favorable safety profile and is considered safe for long-term, consistent topical use.24 It is a peptide that naturally occurs in the body, does not appear to lead to tolerance, and produces fewer systemic effects compared to many other peptides.
