Overview

The original incretin mimetic, derived from a peptide found in Gila monster venom, and the compound that established the class.

Exenatide is classified as a glp-1 receptor agonist. Its current development status is: fda-approved (branded forms). Multiple randomised controlled trials in humans support the primary claims made for this compound.

The Peptide Institute tracks Exenatide because it is actively sold through research-compound and telehealth channels. Our interest is narrow and specific: what is actually in the vial, whether the label is accurate, and whether the sellers of it can document what they claim. We take no position on whether anyone should use it.
