    Selank allosterically modulates GABAA receptors, raises BDNF in the hippocampus, and shifts monoamine neurotransmitter balance - producing anxiolysis without the sedation or dependence profile of benzodiazepines.

    Target or pathway Reported activity Research significance BDNF elevation Raises hippocampal BDNF expression Provides neurotrophic support that benzodiazepines lack Enkephalin potentiation Inhibits enkephalin-degrading enzymes Boosts endogenous opioid tone, contributing to mood and stress buffering GABA subunit expression Modulates GABRA2 and GABRB1 gene expression Longer-term adaptation of GABAergic signalling rather than just acute modulation

  • Frequently asked questions

    Where can I buy Selank?

    Selank (also known as TP-7) is available directly from New-U Research Compounds at https://new-u.io/peptide/selank. It is supplied as lyophilised research-grade material; every released sale batch is independently verified by Janoshik Analytical and Freedom Diagnostics before it is offered for sale, and orders ship direct from source worldwide (approximately 6–14 business days).

    How much does Selank cost?

    Selank starts at $149 for a 10-vial research pack (10mg per vial) at New-U Research Compounds, with 2 pack sizes listed; single vials from $41 ship as an add-on to a pack order. Orders over $350 ship free.

    Is New-U Selank third-party tested?

    Yes. Released Selank batches are verified by independent laboratories (Janoshik Analytical and Freedom Diagnostics) for identity and purity before they are offered for sale. A public certificate for Selank is not listed yet. Contact support with your order reference if a public certificate for your compound is not yet listed.

    How fast does Selank ship, and do you ship internationally?

    Selank ships discreetly and tracked worldwide. US orders ship from the USA or China depending on stock and fulfilment; all other destinations ship from China, direct from the manufacturer. Delivery takes approximately 6–14 business days worldwide. Shipping is free on orders over $350. Card and cryptocurrency payments are accepted.

    Is it legal to buy Selank?

    In the United States, Selank is not approved by the FDA for human consumption and is not sold for that purpose. Research use only - all claims made on this site are for testing and research use only. Regulatory requirements vary by product, intended use and jurisdiction. Purchasers are responsible for ensuring that acquisition and use of research material complies with applicable requirements.

    What is the typical Selank research dosage?

    Reconstitution volumes and dosing reported in the literature for Selank are described in research-model terms only. New-U Research Compounds supplies Selank strictly for laboratory research and does not provide human-use dosing guidance. Reconstitution math and study-reported ranges are covered on the full research profile.

    What do I use to reconstitute Selank?

    Lyophilised Selank is reconstituted with bacteriostatic water - sterile water with 0.9% benzyl alcohol, the standard multi-use diluent for research peptides. New-U supplies USP-grade bacteriostatic water at https://new-u.io/peptide/bacteriostatic-water, and a free reconstitution calculator at https://new-u.io/tracker/calculator works out the volume for any peptide.

    Can I buy Selank online and how fast does it ship?

    Yes. Selank can be ordered online directly from New-U Research Compounds with card or cryptocurrency, shipped direct from source discreetly worldwide. Delivery is approximately 6–14 business days worldwide. Free shipping applies to orders over $350.

    Can I buy Selank in bulk?

    Selank ships in 10-vial research packs as standard, in 2 pack sizes — the larger mg vials lower the per-mg cost. Multi-pack orders get direct-from-source pricing and free shipping over $350. For wholesale or recurring laboratory-supply volumes, contact New-U Research Compounds at https://new-u.io/contact.

    What should I look for when choosing where to buy Selank?

    For research-grade Selank, verify four things: (1) independent third-party purity testing with a published Certificate of Analysis - New-U uses Janoshik Analytical and Freedom Diagnostics; (2) lyophilised material with documented storage and handling; (3) transparent direct-from-source pricing rather than marketplace markup; and (4) clear research-use-only framing. New-U Research Compounds lists Selank at https://new-u.io/peptide/selank. A public Selank certificate is not listed yet; support answers certificate questions from the order reference.

    What is Selank and how does it work?

    Selank is a synthetic seven-amino-acid (heptapeptide) derivative of the immune peptide tuftsin, with a Pro-Gly-Pro tail for stability, studied as an anxiolytic and nootropic research compound. The leading mechanistic hypothesis is allosteric modulation of the GABAergic system - it changes the expression of GABA-related genes rather than binding the GABA-A receptor as a direct agonist - alongside effects on monoamine neurotransmitters. New-U supplies it for laboratory research only.

    What does the Selank research actually show?

    The headline finding is a Russian clinical study where Selank produced anxiolytic effects similar to the benzodiazepine medazepam, plus additional antiasthenic (anti-fatigue) and psychostimulant activity (Zozulya et al., 2008). Mechanistic work shows it modulates GABAergic gene expression (Volkova et al., 2016). These are research findings - mostly from Russian clinical and animal studies - and are not a promise of any effect in humans.

    How does Selank compare with benzodiazepines?

    A Russian clinical study compared Selank directly with medazepam and found comparable anxiolytic effect. The reported difference is in the side-effect profile: review and clinical literature describe Selank as not producing sedation, amnesia, tolerance, dependence or withdrawal, which are common with benzodiazepines. It is studied as an allosteric GABAergic modulator rather than a direct GABA-A agonist.

    How long does Selank take to work, and what is its half-life?

    Plasma clearance is rapid - effectively complete within minutes of administration - but the Pro-Gly-Pro tail extends functional activity far beyond the parent tuftsin, whose half-life is measured in seconds. Russian clinical and review sources describe a fast onset for the anxiolytic effect via the intranasal route. We report these figures descriptively from the literature and make no dosing recommendation.

    Is Selank legal, and is it FDA-approved?

    Selank is not FDA-approved in the United States and is sold strictly as a research chemical for laboratory use, not for human consumption. It is a registered/approved anxiolytic medicine in Russia. Legal status varies by jurisdiction, so confirm your local rules before purchasing.

    How does Selank compare with Semax?

    Both are Russian heptapeptides with Pro-Gly-Pro stabilising tails and intranasal delivery, and they share several effects such as monoamine modulation. Selank emphasises anxiolysis and stress buffering; Semax (an ACTH(4-10) analogue) emphasises cognition and neuroprotection. They are sometimes studied together in protocols covering both the calm and the focus dimensions.

    How should Selank be stored?

    Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1-6 °C and protect from light. The Pro-Gly-Pro tail gives Selank much better stability than parent tuftsin (which has a half-life measured in seconds), but standard peptide handling still applies - avoid repeated freeze-thaw cycles.
