Glepaglutide
As a GLP-2 receptor agonist, glepaglutide has a trophic effect on the intestinal mucosa, enlarging the absorptive surface and thereby improving intestinal uptake of nutrients and fluid.
Octreotide
Octreotide is a cyclic octapeptide that selectively binds somatostatin-receptor subtypes SSTR2 and SSTR5. Via G-protein-coupled signalling, adenylyl cyclase is inhibited, reducing the secretion of multiple hormones (growth hormone, IGF-1, glucagon, insulin, VIP, serotonin). Structural stabilisation via a disulfide bridge and D-amino acids extends the half-life relative to natural somatostatin (minutes to several hours).

Frequently asked questions
- What is the difference between Glepaglutide and Octreotide?
- Glepaglutide is classified as "Research other", while Octreotide is classified as "Research other". Glepaglutide: Glepaglutide is a long-acting GLP-2 analogue (Zealand Pharma) intended to reduce the need for parenteral support in short bowel syndrome. Octreotide: Synthetic octapeptide somatostatin analog with a longer half-life than endogenous somatostatin. FDA- and EMA-approved since the 1980s for acromegaly and neuroendocrine tumours. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Glepaglutide or Octreotide?
- The highest available evidence level is "Human RCT" for Glepaglutide and "Human RCT" for Octreotide. 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 Glepaglutide and Octreotide in Germany and the United States?
- Germany: Glepaglutide — Unapproved, Octreotide — Prescription. United States: Glepaglutide — Unapproved, Octreotide — Prescription. These are factual summaries with source and review date on the individual pages.
