Comprehensive side-by-side comparison of mechanisms, dosing, side effects, and research
Also: Copper Peptide, Glycyl-L-histidyl-L-lysine copper
A naturally occurring copper-binding peptide found in human plasma, saliva, and urine. Widely used in skincare for its wound healing and anti-aging properties.
Also: Tripeptide-3, Ala-His-Lys Copper
A copper-binding tripeptide primarily used for hair growth stimulation. Shows promise for both hair loss prevention and scalp health.
Key Comparison Insights
- Both peptides belong to the Skin & Hair category, suggesting similar primary applications.
Detailed Comparison
| Attribute | GHK-Cu | Copper Peptide AHK-Cu |
|---|---|---|
| Category | Skin & Hair | Skin & Hair |
| FDA Status | Not FDA Approved | Not FDA Approved |
| Clinical Status | Pre I II III IV FDA | Pre I II III IV FDA |
| Mechanism of Action | GHK-Cu stimulates collagen and elastin synthesis, promotes glycosaminoglycan production, supports blood vessel growth, and has antioxidant and anti-inflammatory properties. It remodels damaged tissue and activates wound-healing genes. | AHK-Cu binds copper and delivers it to hair follicles where it supports various enzymatic processes. It stimulates hair follicle cells, extends the growth phase of hair, and has wound-healing properties on the scalp. |
| Common Dosing | 1-2 mg daily (injection) or topical Once daily | Limited community data available See research protocols |
| Administration | Subcutaneous injection or topical application | Topical (scalp serums, solutions) |
| Typical Duration | Varies by application | 3-6 months for visible results |
| Best Time to Take | Evening (for skin/recovery) | Morning or as directed |
Possible Side Effects May vary by individual |
|
|
| Research Summary | Studies demonstrate increased collagen synthesis, improved skin elasticity, reduced fine lines, and accelerated wound healing. Research shows it can reset gene expression to a healthier state and may have systemic anti-aging effects beyond skin. | Studies show increased hair count and thickness. Research demonstrates activation of hair follicle stem cells. Often combined with other hair growth peptides for synergistic effects. |
