Alpha Peptides has the lowest single-vial Selank price at $2.31/mg among 42 COA-verified vendors on Disclosed Labs. Bulk or multi-vial deals may be lower. That's 71% less per mg than the most expensive option.
What is the price range for Selank?
Research-grade Selank ranges from $2.31/mg to $7.90/mg across 24 verified sources, a 71% spread per mg.
How are Selank prices verified on Disclosed Labs?
Every listed vendor holds a Grade C or better trust score, computed independently from lab Certificates of Analysis — not from payments or sponsorships. Prices are scraped and fact-checked daily. Vendors cannot pay to improve their ranking.
Selank is among peptides under FDA review; if added to the Category 1 (503A)list it would require a prescription. In April 2026 the FDA removed 12 peptides from Category 2, but removal does not place them on the Category 1 list or authorize compounding — they remain in a regulatory gray zone. The FDA's Pharmacy Compounding Advisory Committee is advisory and meets July 23–24, 2026 to review nominations and make recommendations to the FDA; the FDA issues any final rule later.
Check formulation: Lyophilized powder requires reconstitution before use. Pre-mixed solutions are more convenient but may have a shorter shelf life and higher prices.
Compare per-mg cost: Different strengths and quantities make direct price comparison difficult. Calculate the per-milligram cost to find the true best value.
Verify COAs: Look for vendors that publish per-batch Certificates of Analysis from named, accredited labs. Use the Full safety panel filter to require endotoxin, sterility, and heavy-metals testing on the current batch — not just HPLC purity.
Selank's clinical evidence base is almost entirely Russian. Zozulia et al. (2008, Zh Nevrol Psikhiatr Im S S Korsakova; PMID 18454096) compared selank to medazepam in 62 patients with generalized anxiety disorder and neurasthenia, reporting comparable anxiolytic efficacy plus antiasthenic/psychostimulant effects, together with changes in serum enkephalin-degrading enzyme activity. Mechanistic work includes Inozemtseva et al. (2008, Dokl Biol Sci; PMID 18841804) showing intranasal Selank increases hippocampal BDNF mRNA and protein in rats, Volkova et al. (2016, Front Pharmacol; PMID 26924987) demonstrating modulation of GABAergic gene expression, and Vyunova et al. (2018, Protein Pept Lett; PMID 30255741) proposing a positive allosteric GABA-A mechanism. No US or EU regulatory clinical trials have been conducted; safety data outside Russia is limited.
