Comparison

Hexarelin vs Tirzepatide

Function

While Hexarelin is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs1929, Tirzepatide is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials24.

Mechanism

While Hexarelin works as a potent synthetic hexapeptide (examorelin) that agonizes GHSR-1a to stimulate GH release and also binds CD36, influencing cardiovascular and metabolic pathways19212996, Tirzepatide is a 39-amino-acid synthetic peptide primarily based on GIP sequence with C20 fatty diacid conjugation that acts as a dual agonist at GIP and GLP-1 receptors, enhancing glucose-dependent insulin secretion, suppressing glucagon, delaying gastric emptying, and reducing appetite24.

Length and Sequence

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

Receptor

Hexarelin

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

Tirzepatide

Glucose-dependent insulinotropic polypeptide receptor (GIPR) and GLP-1 receptor (GLP1R) 24

Hexarelin

Fully synthetic growth hormone secretagogue29

Tirzepatide

Synthetic dual GIP/GLP-1 receptor agonist modeled on human incretin hormones2480
