Mechanism of action
Nafarelin
Nafarelin is a potent GnRH agonist: after an initial stimulation ('flare'), continuous receptor occupancy leads to downregulation and thereby suppression of LH, FSH and the downstream sex hormones.
Plecanatid
Plecanatide is structurally analogous to the body's own uroguanylin and, like it, activates the GC-C receptor at the gut surface, raising cGMP and fluid secretion. Its pH-dependent activity shifts the effect toward the proximal small intestine.

Frequently asked questions
- What is the difference between Nafarelin and Plecanatid?
- Nafarelin is classified as "Research other", while Plecanatid is classified as "Research other". Nafarelin: Nafarelin is a GnRH agonist and the only member of this class delivered as a nasal spray. It is approved for treating endometriosis and central precocious puberty. Plecanatid: Plecanatide is a 16-amino-acid analog of the body's own uroguanylin and a guanylate cyclase-C (GC-C) agonist. It is approved for chronic idiopathic constipation (CIC) and IBS with constipation (IBS-C). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Nafarelin or Plecanatid?
- The highest available evidence level is "Human RCT" for Nafarelin and "Human RCT" for Plecanatid. 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 Nafarelin and Plecanatid in Germany and the United States?
- Germany: Nafarelin — Prescription, Plecanatid — Unapproved. United States: Nafarelin — Prescription, Plecanatid — Prescription. These are factual summaries with source and review date on the individual pages.
