Anti-Aging and Skin Biology Research Peptides
Research into peptide-mediated mechanisms of cellular aging, collagen remodelling, skin repair, and melanocortin signalling has produced a substantial and growing preclinical literature. Three compounds with well-characterised research bases in these areas are GHK-Cu, PT-141, and Melanotan II — each acting through distinct but complementary biological pathways.
GHK-Cu (glycine-histidine-lysine copper complex) is a naturally occurring tripeptide found in human plasma that binds copper(II) with high affinity. Research has documented its effects on fibroblast proliferation, collagen and elastin synthesis, matrix metalloproteinase regulation, wound healing, antioxidant gene expression (SOD1, CAT), and cellular senescence pathways. PT-141 (Bremelanotide) is a cyclic heptapeptide metabolite of Melanotan II with research focus on MC3R and MC4R receptor agonism. Melanotan II (MT-II) is a synthetic cyclic analogue of alpha-MSH with broad melanocortin receptor activity studied for skin pigmentation and photoprotection in melanocyte models.

Frequently Asked Questions
What peptides are used in anti-aging research in Australia?
GHK-Cu, PT-141, and Melanotan II have well-characterised research bases in anti-aging and skin biology. GHK-Cu is the primary compound studied for collagen synthesis and skin repair; PT-141 and Melanotan II are studied for melanocortin receptor signalling pathways. All are available wholesale from Eternal Peptides. For laboratory research use only.
What is GHK-Cu used for in anti-aging research?
GHK-Cu (copper tripeptide-1) has been studied for its effects on fibroblast proliferation, collagen synthesis, elastin production, matrix metalloproteinase regulation, wound healing, and antioxidant gene expression. It has also been investigated in cellular senescence models. Supplied as CU50 (5mg) and CU10 (10mg) box of 10 vials. For research use only.
What is the difference between PT-141 and Melanotan II?
MT-II is a broad-spectrum MC1R-MC5R agonist studied primarily for melanocyte pigmentation. PT-141 is a metabolite of MT-II with more selective MC3R/MC4R activity, studied for central melanocortin signalling. They are structurally related but have different receptor selectivity profiles relevant to research model design. For research use only.
