AHK-Cu (Ala-His-Lys-Copper) is a copper chelating tripeptide related to but distinct from GHK-Cu (Gly-His-Lys-Copper). Where GHK-Cu is the most-studied copper peptide and naturally occurs in human plasma, AHK-Cu is a synthetic structural analog with enhanced copper-chelating affinity. Both peptides activate hair follicle stem cells and promote keratinocyte proliferation, but AHK-Cu appears to have stronger follicle-stimulating activity in some preclinical comparisons. Research applications center on androgenetic alopecia, scalp vascularity, and wound healing, typically in topical formulations or via mesotherapy injection. AHK-Cu is used in cosmetic compounding for scalp treatments targeting hair miniaturization. What forms does AHK-Cu come in? AHK-Cu is available in vial, powder forms. How much does AHK-Cu cost? Prices start at $63.00 across 1 verified vendor. How do I compare AHK-Cu vendors?

Acetyl Hexapeptide-8 (INCI: Acetyl Hexapeptide-3 in older nomenclature, commercially known as Argireline) is a synthetic hexapeptide designed as a competitive inhibitor of the SNARE complex at the neuromuscular junction. t½ Short (topical application, no systemic absorption at cosmetic doses) 0 Preclinical View Profile ](/compound/acetyl-hexapeptide-8)[ ### Melanotan 2 Skin & Hair Discontinued (early clinical) A synthetic melanocortin receptor agonist studied for skin tanning, sexual function, and appetite suppression.. t½ ~1–2 hours 100-1,000 mcg per injection Preclinical View Profile ](/compound/melanotan-2)[ ### Minoxidil Skin & Hair FDA-Approved Minoxidil is an FDA-approved treatment for pattern hair loss. t½ Oral minoxidil plasma half-life is approximately 3-4 hours; the hair-growth (pharmacodynamic) effect is independent of plasma level and depends on ongoing daily use. Oral low-dose minoxidil (off-label): 625-5000 mcg/day (0.625-5 mg). Topical minoxidil is dosed by concentration (2% or 5%), not by mcg -- roughly 10-20 mg of minoxidil is delivered per topical application, with only ~1.4% absorbed systemically.
