Lanreotid
Lanreotide activates somatostatin receptors (chiefly SSTR2, additionally SSTR5), thereby suppressing the release of growth hormone, IGF-1 and various gastrointestinal and neuroendocrine hormones. It is metabolically far more stable than natural somatostatin.
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 Lanreotid and Selank?
- Lanreotid is classified as "Research other", while Selank is classified as "Research other". Lanreotid: Lanreotide is a synthetic cyclic octapeptide analog of somatostatin. It binds preferentially to the somatostatin receptors SSTR2 and SSTR5 and is approved for treating acromegaly and certain neuroendocrine tumours. 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, Lanreotid or Selank?
- The highest available evidence level is "Human RCT" for Lanreotid and "Human trial" 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 Lanreotid and Selank in Germany and the United States?
- Germany: Lanreotid — Prescription, Selank — Unapproved. United States: Lanreotid — Prescription, Selank — Unapproved. These are factual summaries with source and review date on the individual pages.
