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.
Bremelanotide
Bremelanotide is a cyclic peptide that binds non-selectively to melanocortin receptors (MC1R through MC5R) — with highest affinity at MC4R in the central nervous system. The precise role of MC4R activation in sexual behaviour is not fully understood; animal data show effects on hypothalamic circuits. Peripheral effects (blood pressure, hyperpigmentation) are attributed to MC1R/MC2R.

Frequently asked questions
- What is the difference between Plecanatid and Bremelanotide?
- Plecanatid is classified as "Onderzoek (overig)", while Bremelanotide is classified as "Onderzoek (overig)". 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). Bremelanotide: Synthetic cyclic heptapeptide acting as a non-selective melanocortin-receptor agonist. FDA-approved in 2019 as Vyleesi for hypoactive sexual desire disorder (HSDD) in pre-menopausal women. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Plecanatid or Bremelanotide?
- The highest available evidence level is "Humane RCT" for Plecanatid and "Humane RCT" for Bremelanotide. 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 Plecanatid and Bremelanotide in Germany and the United States?
- Duitsland: Plecanatid — Niet goedgekeurd, Bremelanotide — Niet goedgekeurd. Verenigde Staten: Plecanatid — Op recept, Bremelanotide — Op recept. These are factual summaries with source and review date on the individual pages.
