Goserelin
As a GnRH agonist, goserelin binds to the GnRH receptors of the pituitary gland. Initial stimulation transiently raises luteinizing hormone (LH) and follicle-stimulating hormone (FSH). With continuous receptor occupancy, however, the receptors become desensitized and down-regulated, which reduces LH and FSH secretion and consequently the production of testosterone or estrogen. This mechanistic relationship is documented in the pharmacological literature.
Selank
Selank is a glyproline-tuftsin analog. Proposed mechanisms include modulation of the GABAergic system, effects on serotonin bioavailability, and influence on enkephalinases. Animal studies show anxiolytic and neuroprotective markers; a clear receptor target is not established.

Frequently asked questions
- What is the difference between Goserelin and Selank?
- Goserelin is classified as "Onderzoek (overig)", while Selank is classified as "Onderzoek (overig)". Goserelin: Goserelin is a synthetic decapeptide and an agonist of gonadotropin-releasing hormone (GnRH). The medical literature describes it as a hormonal agent that suppresses the release of sex hormones through sustained receptor stimulation. Regulatory-approved indications include prostate cancer, advanced breast cancer, endometriosis, and endometrial thinning, among others. Selank: Synthetic heptapeptide derived from natural tuftsin. Approved as an anxiolytic (Selank) in Russia and some CIS states. Western phase-3 trials are absent; efficacy assessment relies on Russian research literature. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Goserelin or Selank?
- The highest available evidence level is "Humane RCT" for Goserelin and "Humane studie" for Selank. 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 Goserelin and Selank in Germany and the United States?
- Duitsland: Goserelin — Op recept, Selank — Niet goedgekeurd. Verenigde Staten: Goserelin — Op recept, Selank — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
