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.
Teriparatid
Teriparatide corresponds to the biologically active first 34 amino acids of human parathyroid hormone and binds the PTH-1 receptor on bone and kidney cells. The literature describes that intermittent receptor activation preferentially stimulates the activity of bone-forming osteoblasts, whereas continuously elevated PTH exposure (as in hyperparathyroidism) tends to favor bone resorption. This time-dependent difference is regarded as the mechanistic basis for the bone-anabolic effect observed in studies.

Frequently asked questions
- What is the difference between Selank and Teriparatid?
- Selank is classified as "Onderzoek (overig)", while Teriparatid is classified as "Onderzoek (overig)". 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. Teriparatid: Teriparatide is the recombinant N-terminal fragment 1-34 of human parathyroid hormone (PTH). It is regulatory-approved and studied in the scientific literature as a bone-anabolic agent for the treatment of osteoporosis. Unlike antiresorptive agents, studies attribute to it an effect that stimulates new bone formation. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Selank or Teriparatid?
- The highest available evidence level is "Humane studie" for Selank and "Humane RCT" for Teriparatid. 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 Selank and Teriparatid in Germany and the United States?
- Duitsland: Selank — Niet goedgekeurd, Teriparatid — Op recept. Verenigde Staten: Selank — Niet goedgekeurd, Teriparatid — Op recept. These are factual summaries with source and review date on the individual pages.
