Reconstitution

Pen format? Pens are supplied pre-mixed and ready for research use — no reconstitution required. The steps below apply to lyophilized vials only.

Swab both vial stoppers with alcohol and allow to dry.
Draw the required volume of bacteriostatic water with a sterile syringe.
Add the water slowly down the inside wall of the vial — never directly onto the powder.
Swirl gently until fully dissolved. Never shake.
Confirm the solution is clear and particle-free.
Label with date and concentration, then refrigerate at 2–8 °C.

Storage & Handling

Lyophilized vials: refrigerate sealed at 2–8 °C away from light; freeze at −20 °C for storage beyond 6 months.
After reconstitution: refrigerate at 2–8 °C; typically stable 4–8 weeks with bacteriostatic water. Do not freeze once mixed.
Pre-mixed pens: arrive ready to use — refrigerate at 2–8 °C with the cap on and never freeze.
General: avoid direct sunlight, heat and repeated temperature swings; minimise agitation.

GHK-Cu (Copper Tripeptide-1)

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) whose concentration in the body declines with age. It is one of the most widely studied peptides in dermatological and regenerative research.

About the compound

In laboratory research, GHK-Cu has been investigated for its role in extracellular-matrix signalling — including studies examining collagen and elastin gene expression in human dermal fibroblast models, and its interactions with copper transport. Its antioxidant and matrix-remodelling pathways remain active areas of published research.

GHK-Cu Tripeptide Improves Collagen Density and Reduces MMP Activity in Human Skin

Journal of Investigative Dermatology · Simeon et al., 2000

Clinical and ex vivo evaluation of GHK-Cu on human skin demonstrated significantly increased type I and III collagen gene expression, proteoglycan synthesis, and dermal remodelling. Biopsies showed measurably increased collagen density and improved extracellular matrix organisation, with reductions in MMP activity that would otherwise degrade structural proteins. In photoaged skin participants, investigators reported significant improvements in skin thickness, firmness, and fine line depth.

GHK-Cu: Collagen Synthesis Stimulation and Tissue Remodelling Research

Journal of Peptide Science · Pickart & Margolina, 2018

GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring tripeptide with strong affinity for copper ions. In vitro research characterised its role in stimulating collagen and glycosaminoglycan synthesis in dermal fibroblasts through TGF-β signalling activation. Additional findings confirm potent antioxidant activity and promotion of angiogenesis, establishing GHK-Cu as a widely studied compound in dermatological and tissue remodelling research.

Regenerative and Protective Actions of the GHK-Cu Peptide in Light of New Gene Data

Int. J. Molecular Sciences · Pickart & Margolina, 2018

A review of gene-expression data for the copper tripeptide GHK-Cu, a plasma peptide that declines with age. Broad transcriptomic analyses indicate GHK-Cu modulates the expression of a large number of human genes, resetting many toward a healthier state, and stimulates collagen and decorin synthesis in fibroblasts at nanomolar concentrations. The peptide also supports angiogenesis, nerve outgrowth and antioxidant defence.

GHK-Cu May Prevent Oxidative Stress in Skin by Regulating Copper and Antioxidant Genes

Cosmetics · Pickart et al., 2015

An analysis of GHK-Cu's role in skin protection, showing the peptide binds and regulates copper and modifies expression of numerous antioxidant genes. By supporting collagen and glycosaminoglycan production while reducing oxidative stress, GHK-Cu is characterised as a regenerative signal for ageing skin — the mechanistic basis for its widespread use in dermal research.
