Overview
Cosmetic-research peptides are studied for skin, collagen, and pigmentation-related signaling, often in in-vitro or topical-model contexts. This guide describes the researched mechanism and handling as research characterization, not a cosmetic-outcome claim.
A copper-binding tripeptide (GHK) complexed with copper, studied for collagen synthesis and dermal-remodeling signaling.
Evidence at a glance: Mechanistic / in-vitro only
The published record here is mechanistic or in-vitro only. No human-efficacy conclusion can be drawn from it.

Researched mechanism
Studied for stimulation of collagen/elastin synthesis and dermal remodeling; the copper complex is central to activity.
Described as a mechanism characterized in the literature, not an effect you should expect from use.
What the published research shows
Collagen-stimulating and skin-remodeling effects in in-vitro and topical studies.
Every citation states its study type and population, so preclinical data is never presented as human-efficacy evidence.

Reconstitution
Concentration math only: adding bacteriostatic water to the vial gives the resulting mg/mL shown below. This is not usage guidance.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 50 mg | 3 mL | 16.67 mg/mL |
| 100 mg | 4 mL | 25 mg/mL |
Storage & stability
| State | Temperature | Duration |
|---|---|---|
| Lyophilized (unopened) | -20°C | 24 months |
| Reconstituted | 2–8°C | up to 4 weeks |
Common questions
Why is the powder blue?+
The copper complex gives GHK-Cu its characteristic blue color, a useful visual identity check.
