Research use only. Selank is sold strictly as a reference material for in-vitro and laboratory research. Nothing here is medical advice, an anxiety treatment, a dosing protocol, or a statement of human efficacy — it summarises how the published literature characterises the peptide. Every batch we list is published with its independent Janoshik HPLC certificate.
What Selank is
Selank is a synthetic heptapeptide developed in Russia, based on the endogenous immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg) with additional residues added for stability. Because its parent peptide is tuftsin, the literature investigates Selank along two tracks at once: a regulatory/anxiolytic track in the nervous system and an immunomodulatory track — an unusual dual profile for a short peptide.
What the research investigates
- Anxiolytic activity. The headline research theme — studied for anxiety-reducing effects in animal models, with the literature emphasising that, unlike benzodiazepines, the models do not show sedation, muscle relaxation, or dependence/withdrawal.
- GABA and serotonin systems. Proposed interactions with GABAergic and monoaminergic signalling appear across the mechanistic literature.
- BDNF and neuroplasticity. Like Semax, Selank has been associated with neurotrophic-factor expression in studies.
- Immunomodulation. Reflecting its tuftsin origin, a separate strand examines effects on immune signalling.
Selank and Semax — the research pairing
Selank is most often discussed alongside Semax, the related Russian regulatory peptide. The two are treated as complementary: Selank on the anxiolytic/calming side, Semax on the cognitive/neurotrophic side. Both appear together in Bastion’s cognitive stack grouping.
What the literature does NOT establish
No validated human dosing protocol, no established anti-anxiety efficacy claim for humans outside the Russian clinical literature, and no long-term safety data are asserted here. As with Semax, much of the evidence derives from a single national research tradition. Treat Selank strictly as a laboratory research compound.
Handling and reconstitution
Selank ships as lyophilised powder and must be reconstituted before laboratory work; reconstitution volume sets concentration per unit, so calculate it with our reconstitution guide rather than estimating.
Verifying what you receive
The Selank we list is published with the independent Janoshik HPLC certificate that accompanies its batch — see the lab results archive; the task ID resolves on Janoshik’s own domain.
Frequently asked questions
What is Selank derived from?
It is a synthetic heptapeptide based on tuftsin (Thr-Lys-Pro-Arg) with stabilising residues, giving it both regulatory/anxiolytic and immunomodulatory research profiles.
What is Selank researched for?
Chiefly anxiolytic activity in animal models — notably without the sedation or dependence associated with benzodiazepines — plus GABA/serotonin interactions, BDNF, and immunomodulation.
How is Selank different from Semax?
They are complementary regulatory peptides: Selank is studied on the anxiolytic/calming side, Semax on the cognitive/neurotrophic side. They are frequently co-studied.
Does Selank cause sedation or dependence in research models?
The anxiolytic literature specifically contrasts Selank with benzodiazepines, reporting anxiety-related effects without the sedation, muscle relaxation, or dependence seen with that drug class — in research models.
How do I verify the purity of the batch I receive?
Each batch we list is published with its independent Janoshik HPLC certificate and a public verify link on Janoshik’s own domain.
Is Selank for human use?
No. It is sold strictly as a research-use-only reference material and is not intended for human or veterinary use.
Summary
Selank is a tuftsin-analog heptapeptide studied for anxiolytic effects without benzodiazepine-style sedation or dependence, plus an immunomodulatory strand — the calming half of the Semax/Selank research pairing. Match it to the research question, reconstitute it correctly, and confirm the batch against its published Janoshik certificate.
