Exenatide
Exenatide is a 39-amino-acid peptide with about 53% sequence homology to human GLP-1. A glycine substitution at position 2 prevents dipeptidyl-peptidase-IV cleavage and extends the half-life from native GLP-1 (minutes) to about 2.4 hours. GLP-1 receptor activation glucose-dependently stimulates insulin secretion, inhibits glucagon and delays gastric emptying.
Liraglutide
Liraglutide is a synthetic GLP-1 analog with 97% sequence identity to human GLP-1. A fatty-acid side chain (C16) on Lys-26 reversibly binds serum albumin and protects against DPP-4 degradation. GLP-1 receptor activation glucose-dependently stimulates insulin secretion, inhibits glucagon secretion, delays gastric emptying and modulates central satiety.

Frequently asked questions
- What is the difference between Exenatide and Liraglutide?
- Exenatide is classified as "Metabolico", while Liraglutide is classified as "Metabolico". Exenatide: Synthetic version of exendin-4, originally isolated from the saliva of the Gila monster (Heloderma suspectum). First GLP-1 receptor agonist, FDA-approved 2005 as Byetta. Weekly depot form Bydureon approved 2012. Liraglutide: GLP-1 receptor agonist with a half-life of about 13 hours. The first daily (not weekly) modern GLP-1 RA — approved as Victoza for type 2 diabetes (2010) and Saxenda for obesity (2014). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Exenatide or Liraglutide?
- The highest available evidence level is "RCT sull'uomo" for Exenatide and "RCT sull'uomo" for Liraglutide. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Exenatide and Liraglutide in Germany and the United States?
- Germania: Exenatide — Su prescrizione, Liraglutide — Su prescrizione. Stati Uniti: Exenatide — Su prescrizione, Liraglutide — Su prescrizione. These are factual summaries with source and review date on the individual pages.
