Mechanism of action
Histrelin
Continuous GnRH-agonist stimulation downregulates and desensitises the pituitary GnRH receptors — after the initial rise, LH, FSH and the sex hormones fall persistently.
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 Histrelin and Plecanatid?
- Histrelin is classified as "Research other", while Plecanatid is classified as "Research other". Histrelin: Histrelin is a nonapeptide GnRH agonist delivered as a once-yearly implant. Approved for central precocious puberty in children (Supprelin LA) and advanced prostate cancer (Vantas). 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, Histrelin or Plecanatid?
- The highest available evidence level is "Human RCT" for Histrelin 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 Histrelin and Plecanatid in Germany and the United States?
- Germany: Histrelin — Prescription, Plecanatid — Unapproved. United States: Histrelin — Prescription, Plecanatid — Prescription. These are factual summaries with source and review date on the individual pages.
