Comparison
While GHK-Cu acts as a tissue-remodeling and wound-healing signal, enhancing skin regeneration, angiogenesis, and repair while reducing inflammation and oxidative damage in experimental models31383, Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929.
While GHK-Cu works as an endogenous tripeptide, Gly-His-Lys, that chelates Cu²⁺ and modulates gene expression, stimulating collagen, elastin, proteoglycan, and glycosaminoglycan synthesis while exerting antioxidant and anti-inflammatory effects31383, Hexarelin is a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996.
GHK-Cu is 3 amino acids long, whereas Hexarelin is longer as it has a length of 6 amino acids. GHK-Cu is made up of a sequence of Glycine, Histidine, Lysine. Hexarelin is made up of a sequence of Histidine, Tryptophan, Alanine, Tryptophan, Phenylalanine, Lysine.
