GHK-Cu 100mg
Naturally occurring copper tripeptide studied for extracellular matrix remodeling, collagen synthesis, and tissue regeneration.
Mechanism
Acts as a carrier peptide to deliver cellular copper(II), upregulating collagen and elastin synthesis while modulating gene expression associated with tissue repair and antioxidant defense.
Dosing
Standard laboratory reference protocols document an initial dose of 1.0 mg administered subcutaneously 5 days per week.
Reconstitution
Diluting a 100 mg vial with 3.0 mL of bacteriostatic water produces a solution concentration of approximately 33.3 mg/mL (33,300 mcg/mL).
Storage
Store unmixed lyophilized powder frozen at -20 °C, and once reconstituted, maintain between 2–8 °C protected from light without refreezing.

Dosing Chart
| Phase / Day(s) | Dose & Frequency | Volume (U-100 units / mL) |
|---|---|---|
| Weeks 1–4 | 1.0 mg (1000 mcg), 5 days/week | 3 units (0.03 mL) |
| Weeks 5–8 | 1.5 mg (1500 mcg), 5 days/week | 4.5 units (0.045 mL) |
| Weeks 9–12+ | 2.0 mg (2000 mcg), 5 days/week | 6 units (0.06 mL) |
Reconstitution Steps
- 1
Draw 3.0 mL of bacteriostatic water into a sterile syringe.
- 2
Release it slowly down the vial's inner wall to limit foaming.
- 3
Swirl or roll gently until the deep-blue solution is fully dissolved — don't shake.
- 4
Label with the date and concentration, then refrigerate at 2–8 °C (35.6–46.4 °F), shielded from light.

Overview
GHK-Cu is an endogenous copper-binding tripeptide composed of glycyl-L-histidyl-L-lysine complexed with a copper(II) ion. Initially isolated from human plasma, natural concentrations of this peptide decrease markedly throughout the aging process. It serves fundamentally as a signaling and transport molecule that shuttles bioavailable copper into cells to participate in essential enzymatic and structural pathways. In preclinical research models, GHK-Cu has demonstrated significant influence over dermal architecture, wound closure dynamics, and extracellular matrix remodeling. Investigations consistently document its capacity to upregulate collagen and elastin gene expression, stimulate angiogenesis, and exert notable antioxidant and anti-inflammatory properties across cell cultures and animal tissues. While GHK-Cu possesses extensive research documentation in topical cosmetic formulations and experimental laboratory settings, systemic administration via subcutaneous injection remains non-FDA approved and strictly experimental. The protocols outlined here serve exclusively to document laboratory reconstitution and dosing math for research purposes.
