Compound	Class	Research area	Summary	Roundup
GHK-CuCopper peptide GHKCopper(II) tripeptide complex · Skin & hair · Longevity	Copper(II) tripeptide complex	Skin & hair · Longevity	GHK-Cu is the copper complex of a naturally occurring tripeptide studied across dermatology, wound-healing, and cosmetic science for decades. It is analytically tractable but frequently sold without adequate identity or copper-content documentation.	Yes
ArgirelineAcetyl hexapeptide-3Cosmetic hexapeptide · Skin & hair	Cosmetic hexapeptide	Skin & hair	Argireline is a widely used acetylated hexapeptide in cosmetic dermatology research, marketed as a topical SNAP-25 mimetic. It is among the most cited cosmetic peptides in formulation literature.	Yes
Copper PeptidesCopper-binding peptidesCopper(II) peptide complexes (class) · Skin & hair	Copper(II) peptide complexes (class)	Skin & hair	Copper peptides refer to a class of copper-binding sequences — chiefly GHK-Cu — studied in dermatology, wound healing, and matrix biology. This library entry covers the class; see the dedicated GHK-Cu roundup for the primary reference compound.	Yes
Melanotan IIMT-IISynthetic cyclic melanocortin agonist · Neuropeptides · Skin & hair	Synthetic cyclic melanocortin agonist	Neuropeptides · Skin & hair	Melanotan II is a synthetic cyclic heptapeptide melanocortin agonist studied in melanogenesis, pigmentation, and central melanocortin signaling research. It is chemically related to bremelanotide (PT-141) but is not an FDA-approved drug product.	Yes
Palmitoyl Pentapeptide-4MatrixylLipidated signal pentapeptide · Skin & hair	Lipidated signal pentapeptide	Skin & hair	Palmitoyl pentapeptide-4 (Matrixyl) is a palmitoylated KTTKS-related pentapeptide studied extensively in cosmetic collagen-stimulation research. Lipidation chemistry requires MS verification beyond simple pentapeptide mass.	Yes
Snap-8Acetyl octapeptide-3Cosmetic octapeptide · Skin & hair	Cosmetic octapeptide	Skin & hair	Snap-8 is an acetylated octapeptide studied in cosmetic science as a SNAP-25–related neuromuscular signaling modulator in topical formulation research. Evidence is predominantly in vitro and short-term cosmetic studies.	Yes
