Peptide profiles.

Naturally occurring copper-binding peptide found in human plasma. Declines significantly with age. Influences over 4,000 genes. Strongest evidence base for topical skin applications.

A proprietary AminoClub peptide blend formulated for skin rejuvenation, cellular repair, and anti-aging. Combines synergistic peptides targeting collagen synthesis, skin barrier function, and cellular regeneration.

Non-selective α-MSH analogue studied for tanning sexual function and appetite suppression. Parent compound of FDA-approved PT-141. Non-selectivity creates more side effects.

Human host defense peptide with broad-spectrum antimicrobial and wound-healing properties. Naturally produced by immune cells. Dual antimicrobial plus healing mechanism is unique.

Topical SNARE-inhibiting peptide that reduces facial expression lines by decreasing muscle contraction intensity. Often called a Botox alternative. Multiple human RCTs with wrinkle reduction data.

Signal peptide that mimics collagen breakdown fragments to stimulate fibroblasts to produce collagen elastin and fibronectin. One of the most evidence-backed topical cosmetic peptides with replicated human RCT data.

Extended Argireline analogue with two additional amino acids for potentially greater SNARE inhibition at lower concentration. Often combined with Argireline for additive expression line reduction.

A copper-binding tripeptide in the same family as GHK-Cu but with a different amino acid sequence (Ala-His-Lys versus Gly-His-Lys). AHK-Cu is specifically studied for hair follicle stimulation, scalp health, and hair loss research — a more targeted application than GHK-Cu's broader skin and wound healing profile. Sometimes called Copper Peptide-3.
