Head-to-head comparison of Bromantane and Selank — mechanism, dosing, side effects, legal status, and pricing.
Bromantane (Ladasten) is a synthetic adamantane-derivative small molecule — not a peptide — developed in Russia as an "actoprotector"/adaptogen with combined mild psychostimulant and anxiolytic activity. It is an approved prescription drug in Russia (Ladasten) for asthenic disorders, but it has no FDA or EMA approval and no blinded, placebo-controlled human trials. It is prohibited in sport (WADA S6 stimulant) and circulates on the gray market as a research chemical.
Selank is a synthetic heptapeptide analog of the endogenous immunomodulatory tetrapeptide tuftsin, extended with a Pro-Gly-Pro C-terminus for metabolic stability. Developed at the Institute of Molecular Genetics (Russian Academy of Sciences), it is registered as an anxiolytic drug in Russia but is not approved by the FDA or EMA.

Selank is among peptides under FDA review for the Category 1 (503A) list; if added, it would require a prescription to be compounded by registered 503A/503B pharmacies — not yet authorized. Bromantane remains research-only. In April 2026 the FDA removed 12 peptides from Category 2, which does not place them on the Category 1 list or authorize compounding. The FDA's Pharmacy Compounding Advisory Committee is advisory and meets July 23–24, 2026 to review nominations and make recommendations to the FDA.
Human evidence is limited to Russian clinical use of Ladasten. The largest published dataset is an open-label, non-comparative multicenter trial (28 centers, N=728) in asthenic disorder at 50–100 mg/day for 28 days (Voznesenskaia et al., 2010), reporting symptomatic improvement (CGI-S response 76.0%, CGI-I 90.8%) with adverse effects in ~3% of patients. No blinded, placebo-controlled randomized trial exists and there is no ClinicalTrials.gov registration. All mechanistic and toxicology data are preclinical (rat, mouse, in-vitro). Approved only in Russia; not FDA/EMA-approved; not a peptide.
Key references
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.
Bromantane and Selank are both in the Cognitive category and may have overlapping mechanisms. Researchers should review both profiles carefully, understand the mechanisms of action, and monitor the relevant biomarkers when combining compounds in the same class. As always, consult a licensed healthcare provider before making any decisions about combining research compounds.
