AHK-Cu vs SNAP-8 / Argireline

AHK-Cu vs SNAP-8 / Argireline — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

AHK-Cu
Skin & Cosmetic

AHK-Cu is a copper-chelating tripeptide (Ala-His-Lys) that functions as a hair follicle stimulant and skin regeneration signal. Related to the more widely studied GHK-Cu, AHK-Cu has shown specific activity in promoting hair follicle stem cell proliferation and inhibiting DHT-rela...

SNAP-8 / Argireline
Skin & Cosmetic

SNAP-8 and Argireline are related cosmetic peptides that reduce wrinkle depth by partially inhibiting the SNARE complex involved in neurotransmitter vesicle release at the neuromuscular junction. Argireline (Acetyl Hexapeptide-3) is a 6-amino acid fragment; SNAP-8 (Acetyl Octapep...
