GHK-Cu
SkinCopper tripeptide studied in dermatology for skin remodeling and wound contexts. Topical formulations are widely used in cosmetics.
Argireline (Acetyl Hexapeptide-8)
SkinSynthetic hexapeptide (Glu-Glu-Met-Gln-Arg-Arg) marketed as a topical 'botox alternative.' Theoretically interferes with SNARE complex formation, reducing neurotransmitter release at neuromuscular junctions. Topical formulations are widely sold in cosmetics. Effect size is modest at best in published trials.
Melanotan II
SkinSynthetic analog of α-melanocyte-stimulating hormone (α-MSH). Binds melanocortin receptors (notably MC1R for tanning and MC4R for sexual function). Originally researched for therapeutic skin pigmentation; abandoned in clinical development. Sold heavily as a grey-market 'tanning peptide.' Significant safety concerns — Class A action by some regulators.
