Before you buy

What should you check before you buy Selank?

Check that the certificate proves the batch is Selank, not only that the sample is pure, and that the listing says which form of the peptide it is selling. The released batch, lot SEL-260406-A, shows identity by LC-MS, 99.10% purity by HPLC against a not-less-than 95.0% release criterion, and 10.19 mg of net content in a 10mg vial.

  • Selank or N-Acetyl Selank Amidate. N-Acetyl Selank Amidate is a chemically modified, distinct compound. What ships here is plain Selank, so a listing should say which of the two it sells and the certificate should match that name.
  • Vial or spray. What ships here is a lyophilized powder in a sealed vial. Peptara Labs does not sell a ready-made spray and publishes no recipe for making one.
  • Identity, not only purity. A purity figure says a sample is mostly one compound; the LC-MS identity result is what says that compound is Selank.
  • The rest of the panel. Titreon Analytical's certificate also reports net content, sterility, bacterial endotoxin, heavy metals and a fentanyl screen.
  • Your own batch. Vials ship unlabeled on purpose, so verification runs on your order number. Send it to us on WhatsApp and we will confirm the exact batch you received and its published certificate.

The checks that apply to any seller are in how to verify peptide purity, and the full certificate for this batch is on the Selank certificate card.

The short answer

What is Selank?

Selank is a synthetic peptide based on the natural immune-regulating peptide tuftsin, developed in Russia and studied as an anxiolytic, meaning a calming agent, that does not carry the sedation or dependence associated with benzodiazepines. Research links its effects to GABA and serotonin signaling and to BDNF (Vyunova et al., 2018; Filatova et al., 2017), and a Russian clinical study compared its anxiolytic effect and tolerability with the benzodiazepine phenazepam in anxiety disorders (Medvedev et al., 2014). Outside Russia it is treated as a research compound, because the large independent Western trials common to approved drugs do not exist for it, which is the central caveat here. Published protocols describe intranasal and subcutaneous use in short courses, reported in units rather than mL, and those figures are what studies used, not a dose for anyone.

The Science

A Neuropeptide for Calm

Selank is studied for its influence on GABA, serotonin, and BDNF signaling, the systems involved in anxiety and mood. As with Semax, most of the research comes from Russian groups, so we frame it as promising rather than proven.

GABA & Serotonin

Studied for effects on the neurotransmitter systems that regulate anxiety and mood.

No Sedation

The studied profile is anxiolytic without the sedation associated with traditional anxiolytics.

Non-Dependence

Studied for a calming effect without the dependence profile of benzodiazepines.

Applications

Common Use Cases

Everyday Stress

Stress-response endpoints in generally healthy populations are the studied research area.

Focus Without Edge

Attention endpoints appear alongside the anxiolytic ones in the published work.

Semax Stack

Paired with Semax to balance focus with calm.

Sleep Wind-Down

Evening administration is described in reported protocols; it is not a studied endpoint of its own.

Dosage, as studied

What doses and routes did Selank studies use?

Published Selank protocols describe two routes, intranasal and subcutaneous, given in short courses rather than continuously. Intranasal, as drops or a spray, is the route most commonly described in the Russian literature (Medvedev et al., 2014). The table below summarizes how studies frame each route. It is a record of what the research describes, not a dose for any person, and every figure is reported in units rather than mL.

RouteHow studies describe itSchedule
IntranasalDrops or spray; most commonly described routeShort, pulsed courses
SubcutaneousInjection; also appears in the literatureShort, pulsed courses

We do not publish a milligram dosage chart for Selank: specific human dose figures are not well established in the limited independent record, and picking a dose is a clinical decision, not something to copy from a protocol. The reconstitution calculator works the dilution math for a 10mg vial so a studied amount can be read in units.

Comparison

Selank vs Semax: how do they compare?

Selank and Semax are sister peptides from the same Russian research tradition, and they are often studied and stacked together. The short version: Selank leans toward calm and reduced anxiety, while Semax leans toward focus and mental clarity. Selank is an analog of the immune peptide tuftsin studied as an anxiolytic acting on GABA and serotonin signaling (Vyunova et al., 2018); Semax is a fragment-based analog of the hormone ACTH studied for attention, memory, and BDNF.

Common research angleCalm and reduced anxietyFocus and cognition

Because their studied profiles complement each other, the two are frequently paired so calm does not tip into dullness and focus does not tip into overstimulation. See the Semax page for the focus side of the pairing. Neither is an approved drug, and any protocol is a decision for a licensed clinician.

product arrived fine and both vials look good but my tracking number wouldn't load in the carrier's app at first. had to paste it into a browser search instead of scanning or typing it into their tracker. ended up working out, just an extra step i didn't expect. box itself was clean with no dents

one thing i want to highlight is that their team actually walked me through the research side of pt141 instead of just selling it to me. showed me the study, told me where the data was weak, answered every single question i threw at them over two days of back and forth before i committed to buying

i found them through a friend of a friend who does travel medicine and just happens to keep a running list of peptide vendors that actually publish their own lab sheets instead of linking out to somebody else. first order, arrived in about the window they quoted which felt reasonable for an international haul like this one

the tray had a small burr on one edge where the plastic did not get cut all the way through. nothing sharp enough to actually do anything but you could feel it running your finger along the rim, which is not how these should come out of the mold i would think. vials both fine otherwise and the rest of the packaging was solid

Buying Selank: FAQ

Where can I buy Selank peptide?

Peptara Labs sells Selank online as a 10mg research-grade vial, ordered from this page. Outside Russia Selank is treated as a research compound, so it reaches most buyers only as research-grade material sold for laboratory research use, which makes the batch certificate the thing to compare between sources.

How much does Selank cost?

One 10mg vial is $150 USD, which is $15.00 per mg. Signing up by email takes 15 percent off a first order, which brings a vial to $127. Buying more of the same compound lowers the per-vial price on that line, to 40 percent off at 10 vials, which is $90 each.

Does Peptara Labs ship Selank to the US?

Yes. Orders to the United States, Canada, the United Kingdom and New Zealand ship tracked in 5 to 10 business days, guaranteed. Shipping is a flat $35, free over $250.

How do I verify the purity of Selank before I buy?

Read certificate COA-2026-4806 for the released batch, lot SEL-260406-A: 99.10 percent purity by HPLC, identity by LC-MS and 10.19 mg of net content in a 10mg vial, tested by Titreon Analytical, whose panel also reports sterility, bacterial endotoxin, heavy metals and a fentanyl screen. Vials ship unlabeled, so after delivery your order number on WhatsApp is what ties your vial to its batch certificate.

What comes with a Selank order?

One sealed 10mg vial of lyophilized Selank powder and bacteriostatic water to reconstitute it, plus a printed reference guide to what published studies reported. The batch certificate is published on the certificates page, because the vial itself ships unlabeled.

Is Selank sold for human use?

No. Peptara Labs sells Selank as research-grade material for laboratory research use only. It is not a replacement for any prescribed anxiety medication, and nothing on this page is a dose, a route or a recommendation for any person.

Selank FAQ

What is Selank and how does it work?

Selank is a short peptide developed in Russia, structurally related to a natural immune-modulating peptide. Research suggests it influences GABA and serotonin signaling and BDNF, which is the basis for its study as an anxiolytic, meaning a calming agent. It is studied for reducing anxiety and supporting steady mood without the sedation or dependence associated with benzodiazepines. As with Semax, most clinical work comes from Russian groups and large Western trials are limited, so we present it as a promising research compound.

How is it different from Semax?

They are sister peptides often used together. Semax leans toward focus and mental clarity. Selank leans toward calm and reduced anxiety. Many people stack the two so the focus from Semax does not tip into overstimulation, and the calm from Selank does not tip into dullness. See our Semax page for the focus side of the pairing.

Is Peptara Labs a real company?

Yes. Peptara Labs is a registered business with responsive customer support via WhatsApp. Unlike anonymous Telegram sellers, we stand behind every order with our name, reputation, and ongoing support.

Are your peptides real?

Every Selank vial comes with a third-party Certificate of Analysis (COA) confirming 98%+ purity. We source from verified manufacturers and can provide lab documentation upon request. If you want to see a COA before ordering, message us on WhatsApp and we'll send it over.

Will the peptides survive shipping and heat?

Yes. Peptides ship in their lyophilized (freeze-dried powder) form, which is stable at room temperature for weeks. Fast, tracked delivery keeps transit short. Once reconstituted with bacteriostatic water, store the vial in your refrigerator. Storage instructions are included with every order.

How is Selank taken?

The published work describes both an intranasal route, as drops, and a subcutaneous route, with short courses rather than continuous administration. What ships is a reference to the ranges published studies used for both routes, always in units rather than mL. This is educational information, not a prescription; consult a licensed physician.

Is it a replacement for anxiety medication?

No, and this site will not frame it that way. Selank is a research compound, not an approved treatment for any anxiety disorder. A diagnosed condition or a prescribed medication is a matter for a treating physician, and nothing here is a substitute for one.

What about side effects?

Selank is generally reported as well tolerated with a low side-effect profile. Reported side effects include mild nasal irritation with intranasal use or temporary tiredness. As a research compound without large Western safety trials, conservative starting ranges and short cycles are what published research describes. Every order includes an educational research reference. Consult a licensed physician.

How is the 10mg vial reconstituted?

Reconstitution is arithmetic on concentration: the volume of bacteriostatic water against the 10mg in the vial. The reconstitution calculator on this site does that math and reports the result in units rather than mL. Storage instructions ship with every order. For anything medical, including how a compound is administered, speak with a licensed physician.

Does Selank cause withdrawal or dependence?

The reason Selank is studied at all is that it is an anxiolytic that, in the published research, does not carry the sedation, tolerance, or dependence associated with benzodiazepines (Vyunova et al., 2018). Russian work has examined it alongside benzodiazepines such as diazepam and phenazepam (Kasian et al., 2017; Medvedev et al., 2014). It is still a research compound without large independent Western safety trials, so the absence of a withdrawal profile should be read as what the current research describes, not a guarantee. Anything involving a prescribed medication is a matter for a treating physician.

What does the research say about Selank for anxiety?

Anxiety is the endpoint Selank is most studied for. Russian clinical work compared its anxiolytic effect and tolerability with the benzodiazepine phenazepam in anxiety disorders (Medvedev et al., 2014), and animal studies describe it enhancing the anxiety-reducing effect of diazepam (Kasian et al., 2017). Even so, Selank is not an approved treatment for any anxiety disorder, and this page does not frame it as one or suggest a dose. A diagnosed condition belongs with a treating clinician.

What is N-Acetyl Selank Amidate?

N-Acetyl Selank Amidate is a chemically modified form of Selank: an acetyl group and a C-terminal amide are added to slow how quickly the peptide breaks down. It is a distinct compound from plain Selank, which is what this page covers. We make no separate outcome claims for the modified analog.

I can find cheaper peptides on Telegram.

You can. But you don't know what's in them, who made them, or how they were stored. Telegram sellers operate anonymously with no accountability. No COA. No real company behind them. No support if something goes wrong. Our price includes third-party testing, fast delivery, bacteriostatic water, COA access, and educational support. We don't just sell peptides. We stand behind the quality of what we ship, verified purity and certificate of analysis, or your money back.

Is my payment secure?

Yes. We accept Visa, Mastercard and Amex cards, bank transfer, and USDT, USDC or BTC crypto. All transactions are handled securely. For bank transfers, you'll receive confirmation once payment is verified. Your financial information is never stored. If you have concerns about a specific payment method, message us and we'll find an option that works for you.
