Comparison
While Exenatide is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects6768, 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.
While Exenatide works as a 39-amino-acid exendin-4 peptide originally isolated from Gila monster venom that acts as a long-acting GLP-1 receptor agonist resistant to DPP-4 degradation67, GHK-Cu is 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.
Exenatide is 39 amino acids long, whereas GHK-Cu is shorter as it has a length of 3 amino acids. Exenatide is made up of a sequence of sequence data not available in the current dataset. GHK-Cu is made up of a sequence of Glycine, Histidine, Lysine.
