Comparison

Exenatide vs Hexarelin

Function

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, Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929.

Mechanism

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, Hexarelin is a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996.

Length and Sequence

Exenatide is 39 amino acids long, whereas Hexarelin is shorter as it has a length of 6 amino acids. Exenatide is made up of a sequence of sequence data not available in the current dataset. Hexarelin is made up of a sequence of Histidine, Tryptophan, Alanine, Tryptophan, Phenylalanine, Lysine.

Receptor

Exenatide

GLP-1 receptor (GLP1R) 6780

Hexarelin

Primary: GHSR-1a (ghrelin receptor); also binds the scavenger receptor CD36 in vascular and macrophage tissues192129

Originally from Heloderma suspectum (Gila monster) venom; now produced synthetically67

Hexarelin

Fully synthetic growth hormone secretagogue29
