AHK-Cu vs GHK-Cu
| Attribute | AHK-Cu Alanine-Histidine-Lysine copper | GHK-Cu Copper peptide |
|---|---|---|
| Category | Skin, Hair & Beauty | Skin, Hair & Beauty |
| Best known for | Hair growth research | Collagen, wound healing, and hair research |
| In plain English | AHK-Cu is GHK-Cu's hair-focused cousin. Same copper-peptide concept, slightly different sequence with stronger research-interest in follicle stimulation. | GHK-Cu is the most-researched 'beauty peptide.' Researchers study it for everything from anti-aging skincare to wound healing and even hair growth. |
| How it works | Stimulates dermal papilla cells and VEGF expression in research models, encouraging hair follicle activity. | Modulates copper-dependent enzymes, stimulates collagen and elastin synthesis, activates wound healing pathways, and influences hair follicle stem cells. |
| Researchers study | Androgenetic alopecia, hair follicle stimulation, and hair shaft thickening. | Skin appearance, wound healing, hair density, and gene-expression modulation. |
| Internet discussion | Discussed alongside minoxidil and microneedling. | Forums treat it as the king of beauty peptides. Topical vs injectable debate is endless. |
AHK-Cu
Hair growth research
AHK-Cu is GHK-Cu's hair-focused cousin. Same copper-peptide concept, slightly different sequence with stronger research-interest in follicle stimulation.
Stimulates dermal papilla cells and VEGF expression in research models, encouraging hair follicle activity.
Androgenetic alopecia, hair follicle stimulation, and hair shaft thickening.
Discussed alongside minoxidil and microneedling.
AHK-Cu is a copper peptide specifically researched for hair follicle stimulation.
GHK-Cu
Collagen, wound healing, and hair research
GHK-Cu is the most-researched 'beauty peptide.' Researchers study it for everything from anti-aging skincare to wound healing and even hair growth.
Modulates copper-dependent enzymes, stimulates collagen and elastin synthesis, activates wound healing pathways, and influences hair follicle stem cells.
Skin appearance, wound healing, hair density, and gene-expression modulation.
Forums treat it as the king of beauty peptides. Topical vs injectable debate is endless.
GHK-Cu is the most-studied cosmetic peptide, with research on collagen, wound healing, and hair follicle stimulation.
