GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine, a naturally occurring tripeptide present in human plasma, saliva, and urine.

Melanotan II is a synthetic cyclic analog of alpha-melanocyte stimulating hormone (α-MSH), with the structure Ac-Nle4-Asp5-His6-D-Phe7-Arg8-Trp9-Lys10-α-MSH(4-10)-NH2.

Alpha-MSH (α-Melanocyte-Stimulating Hormone) is an endogenous tridecapeptide derived from POMC (pro-opiomelanocortin).

Argireline (Acetyl Hexapeptide-8) is a synthetic hexapeptide used topically to reduce the appearance of expression lines and wrinkles.

Collagen Type I is the most abundant protein in the human body and the predominant structural collagen in skin, bone, tendon, ligament, and cornea.

GHK (Glycyl-L-histidyl-L-lysine) is a naturally occurring human tripeptide found in plasma, saliva, and urine.

Matrixyl (Palmitoyl Pentapeptide-4) is a cosmetic signal peptide consisting of five amino acids (Lys-Thr-Thr-Lys-Ser) conjugated to a palmitoyl chain for enhanced skin penetration.

Zinc Thymulin is a metallopeptide consisting of the nonapeptide thymulin (pyrGlu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn) complexed with a single zinc ion, which is required for its biological activity.

Collagen dipeptides, principally Pro-Hyp (Prolyl-Hydroxyproline) and Hyp-Gly (Hydroxyproline-Glycine), are the primary bioavailable fragments generated during digestion of hydrolyzed collagen supplements.

Collagen peptides are short-chain amino acid sequences derived from enzymatic hydrolysis of native collagen (types I, II, and III).

Palmitoyl Oligopeptide is a generic class of short collagen-fragment peptides conjugated to palmitic acid to enhance skin penetration and stability.

Collagen Type III is the second most abundant collagen in the body, found predominantly in skin, blood vessel walls, internal organs, and muscles.

Epitide, commercially known as MATRIXYL synthe'6 (Palmitoyl Tripeptide-38), is a matrikine-mimetic lipopeptide developed by Sederma.

Palmitoyl Tripeptide-1 (Pal-GHK) is a lipopeptide consisting of the tripeptide sequence Gly-His-Lys conjugated to a palmitic acid chain.

Palmitoyl Tripeptide-38 is a matrikine-mimetic signal peptide derived from tripeptide KMK found naturally in collagen VI and laminin.

PTD-DBM is a synthetic 25-amino-acid research peptide developed by Professor Kang-Yell Choi's lab at Yonsei University.

Palmitoyl Hexapeptide-12 (also marketed as Biopeptide EL) is a lipid-conjugated hexapeptide used in cosmetic formulations.

SNAP-8 is an eight-amino-acid synthetic peptide and extended derivative of Argireline (Acetyl Hexapeptide-3).

SYN-AKE is a patented synthetic tripeptide that mimics the paralytic action of Waglerin-1, a peptide component of the venom of the Temple Pit Viper (Tropidolaemus wagleri).

Heptapeptide-7 is a synthetic seven-amino-acid peptide fragment derived from HB-107, a wound-healing peptide with EGF-like (epidermal growth factor) activity.
