The research behind each vial

GLP3-RT 10 mg

GLP3-RT is a 39-residue lipidated peptide studied as a triple agonist at the GLP-1, GIP and glucagon receptors. It is supplied for laboratory research into multi-receptor incretin signalling, energy expenditure and hepatic lipid metabolism.

GHK-Cu 50 mg

GHK-Cu is the copper(II) complex of GHK (glycyl-L-histidyl-L-lysine), a three-amino-acid peptide first isolated from human plasma by Loren Pickart in the 1970s. It is one of the most-studied peptides in skin-matrix research: cell-culture and rodent studies have measured its effects on collagen and glycosaminoglycan synthesis, matrix metalloproteinases and gene expression, while controlled clinical evidence remains sparse. Peptides Only supplies GHK-Cu as a lyophilized compound for laboratory research only.

Melanotan-2 10 mg

Melanotan-2 (melanotan II, MT-II) is a synthetic cyclic seven-residue analog of alpha-melanocyte-stimulating hormone (alpha-MSH), designed at the University of Arizona. It activates several melanocortin receptors and is used in research as a reference agonist for pathways involved in pigmentation, appetite and sexual function. It has never been approved as a medicine, and Peptides Only supplies it for laboratory research only.
