Quick answers

What is Selank and what is it used for in research?
Selank is classified within the Cognitive & Nootropic group. Heptapeptide derived from tuftsin. Russian-registered anxiolytic; modulates GABAergic and enkephalinergic systems. Research applications focus on the pathways outlined below. All references on this page describe published research only, Selank is supplied for in-vitro and laboratory use, not for human consumption.
How does Selank work?
Primary mechanism: Tuftsin analog; anxiolytic and nootropic activity via enkephalin modulation. Downstream effects depend on dose, timing, and the biological system under investigation. Receptor binding and post-receptor signalling for Selank remain areas of active study, and several proposed effects are supported only by preclinical data.
What is the typical Selank research dose?
Published research protocols for Selank describe per-dose ranges of 250–500 mcg × 2 / day (intranasal), with a weekly total near 3.5–7 mg, administered 2× daily intranasal. Typical cycle: 14 days on / 14 off. These ranges reflect the literature and are not dosing recommendations for any individual.
Where can I buy Selank in Thailand?
Selank is supplied by Thailand Peptides, a Bangkok-based research-peptide supplier. Orders are placed directly via WhatsApp to the Bangkok research desk, no cart, no account, no forms. Pricing and shipping are provided on request. Open a line with the research desk →
How fast can Selank be delivered in Thailand?
Same-week delivery across Thailand is standard for orders confirmed within business hours (GMT+7, Monday–Saturday). Bangkok metro deliveries typically arrive within 1–3 business days; other provinces within 3–5. Regional Southeast Asia shipping is available on request.

What is Selank?

Selank is a research peptide in the Cognitive & Nootropic class. Tuftsin analog; anxiolytic and nootropic activity via enkephalin modulation. It is studied at per-dose ranges of 250–500 mcg × 2 / day (intranasal) (3.5–7 mg weekly), administered 2× daily intranasal over cycles of 14 days on / 14 off. Supplied in Thailand by Thailand Peptides, Bangkok-based, research use only.

Heptapeptide derived from tuftsin. Russian-registered anxiolytic; modulates GABAergic and enkephalinergic systems.

Published and preclinical data are summarised below; dose ranges shown reflect protocols in the research literature and should be interpreted accordingly.

How does Selank work?

Selank is a synthetic heptapeptide analogue of the natural tetrapeptide tuftsin. It produces anxiolytic and nootropic effects in animal models without the sedation or dependence liability of benzodiazepines. Research describes modulation of GABAergic and enkephalinergic systems, elevated BDNF expression in hippocampus, and transcriptomic changes in rat hippocampus and spleen after acute dosing.

Receptor binding affinity and post-receptor signalling for Selank remain areas of active investigation; several proposed effects within the Cognitive & Nootropic class are currently supported only by in-vitro or rodent data, and should be interpreted accordingly.

Stacking Selank

Commonly referenced pairing with Selank: Semax. Stacking rationale should be grounded in complementary mechanisms, not additive speculation; interactions at shared receptors or enzymatic pathways should be accounted for. Both compounds in a Selank stack are supplied by Thailand Peptides on the same order via the Bangkok research desk.

Contraindications

None established. Additional caution is warranted in individuals with hepatic or renal impairment, endocrine disorders, or concurrent pharmacotherapy affecting the pathways described above.
