Compound spec
- Compound
- Selank 0.15% intranasal solution, 3ml. Thr-Lys-Pro-Arg-Pro-Gly-Pro, a tuftsin-derived heptapeptide.
- Form
- 3ml nasal drops, 0.15%
- Kinetics
- Plasma half-life is short, most commonly cited around 2 to 3 minutes, but effects persist for roughly a week. It works by shifting gene expression, not by parking on a receptor.
- Origin
- Fulfilled through a licensed CIS pharmacy network. Selank was developed by the Institute of Molecular Genetics with the Zakusov Institute of Pharmacology and approved in Russia for anxiety since 2009.

Mechanism
It does not block anxiety. It changes what your brain transcribes.
Most anxiolytics work by occupying a receptor. Selank works upstream. It modulates the GABAergic system, inhibits the enzymes that break down your own enkephalins so more of them stay in circulation, and raises BDNF. That gene-expression mechanism is why a peptide with a plasma half-life of only a few minutes produces effects that last about a week. In rat hippocampus, a single intranasal dose increased BDNF mRNA within 3 hours and BDNF protein within 24 hours (Inozemtseva et al., 2008). The human evidence base is real but Soviet and Russian-weighted, and most of it is in anxious patients rather than healthy users.
Tuftsin-derived heptapeptide. GABAergic modulation plus enkephalin and BDNF effects.
Studied for generalized anxiety disorder and adjustment disorders with anxious mood, with anxiolytic effect reported comparable to the benzodiazepine medazepam
Users report calm without sedation, the trait that separates it from a benzodiazepine
No tolerance or withdrawal syndrome documented across the clinical literature
Raises endogenous enkephalins and BDNF, mechanisms associated with mood, resilience, and learning
Commonly stacked with Semax for a calm-plus-focus combination
What Selank actually does
Anxiety relief that does not cost you your edge
No sedation tax
Benzodiazepines buy calm with grogginess, muscle slack, and foggy recall. In Soviet-era Russian head-to-head trials, Selank matched the anxiolytic effect without those costs.
No dependence loop
No tolerance buildup and no withdrawal syndrome have been documented on cessation. This is the central reason people reach for it over a benzodiazepine.

Clinical Science
Studied. Sourced as the original.
This is the original formulation as registered and sold in its home market, not a Western relabel or a powder repack. The mechanism is drawn from the published literature, not from us.
- Modulates the GABAergic system, raises endogenous enkephalins, and upregulates BDNF. Calm without the blunting.
- Peer-reviewed source: Zozulia et al. (2008), Zh Nevrol Psikhiatr Im S S Korsakova, PMID 18454096. Selank vs medazepam in generalized anxiety and neurasthenia.

Ground Truth
The operators already on it.
The shelf the biohacking crowd imports one bottle at a time. Logged, dosed, and compared in the communities that actually track this stuff.
- r/Nootropics: 380k+ members mapping this exact shelf
- Imported one unit at a time by the experimenter crowd for years
- The original CIS-registered product, not a relabeled powder
Same compound, different operator
Where the difference actually shows up.
The molecule is the same as the brand-name competitor and the rest of the offshore field. What separates us is the operational layer: a cash refund in the crypto you paid if your order doesn’t arrive, a customs reship where you cover the postage, discreet pack-out, and direct-source margin we pass through as the crypto discount.
| Razumna | Grey-market peptide vendor | Benzodiazepine (prescription) | |
|---|---|---|---|
| Form | 0.15% intranasal solution, ready to dose | Often lyophilized powder you reconstitute yourself | Oral tablet |
| Sedation | None reported in trials | Same molecule, but purity and concentration unverified | Drowsiness, slowed reaction, muscle relaxation |
| Tolerance / dependence | None documented | None documented for the compound itself | Tolerance and physical dependence are well established |
| Withdrawal | None documented | None documented for the compound itself | Withdrawal syndrome on cessation |
| Sourcing | Licensed CIS pharmacy network | Research-chemical reseller, no pharmacy chain | Pharmacy, requires prescription |
| Honest caveat | Evidence base is Soviet and Russian-weighted | Identity and dose of what arrives is on trust alone | Strong evidence, but the side-effect profile is the problem |

How to use, what to expect
Take it. Here’s what happens.
1
How much
The generalized anxiety trial used 450 mcg 3 times daily (1350 mcg/day) intranasally for 14 days. At 0.15%, 1 drop delivers roughly 75 mcg, so a 450 mcg dose is about 6 drops total, or 2 to 3 drops per nostril. Start at the low end and assess before adding.
2
When
Spread across the day rather than loaded at once, since the trial protocol dosed 3 times daily. Many users keep the last dose away from bedtime, though Selank is not sedating. Effects build over a course rather than from a single dose.
3
Stack
Semax is the classic pairing, anxiolytic Selank plus pro-focus Semax. Keep it apart from benzodiazepines and alcohol; layering depressants is where the real risk sits, not with Selank alone.
4
The limit
Intranasal, so no needles or reconstitution. Refrigerate after opening and use within the labeled window. The evidence base is largely Soviet and Russian and weighted toward anxious patients, not healthy subjects, so claims of cognitive enhancement in healthy users are thin. Not a treatment for a diagnosed disorder, and not a substitute for a prescribed medication you are already on. Speak to a clinician before changing any psychiatric regimen.

Questions
What buyers ask first.
No tolerance buildup or withdrawal syndrome has been documented in the clinical literature. That is the main reason people choose it over a benzodiazepine. It is not a controlled substance in the way benzodiazepines are.
Sedation is the thing Selank is known for not causing. In Soviet and Russian trials it matched the anxiolytic effect of benzodiazepines without the grogginess, muscle slackness, or memory dulling. That said, response varies between people.
Honest answer: real but uneven. There are peer-reviewed human trials in anxious patients and animal mechanism studies, but the body of work is Soviet and Russian-weighted and light on healthy-subject data. Treat the anxiety findings as the strongest part and cognitive-enhancement claims as the weakest.
Selank is well absorbed intranasally, with the route also allowing direct nose-to-brain transport. It means no needles, no reconstitution, and no sterility handling on your end.
No. These are original products registered and sold in their home markets (largely Russia and the CIS), shipped for personal use. Most are not FDA-approved and several are not sold through US pharmacies at all. You are sourcing the originals directly, which is the point.
Dispatched from a licensed CIS pharmacy network, direct to you, with no supplier branding on the parcel. Tracked international, typically 2 to 4 weeks depending on customs. There is a 10-unit-per-order limit on this lane, a customs constraint on the origin side.
Flat $45 on orders under $200, free over $200. The flat rate reflects real tracked-international postage on a low-volume lane. Bundling your order past $200 removes it.
Same policy as the rest of Razumna. If your order is seized or never arrives, you choose a full refund in the crypto you paid, or a reship where you cover the postage. The claim window is 30 days from dispatch and a tracking screenshot is all we need.

Read before you order
No molecule is free. Here is the honest version.
- Human evidence base is Soviet and Russian-weighted and concentrated in anxious patients, not healthy subjects; cognitive-enhancement claims for healthy users are thin
- Not a treatment for any diagnosed anxiety disorder and not a substitute for prescribed psychiatric medication
- Do not stack with benzodiazepines or alcohol; combining depressants is the real risk vector
- Anyone on existing psychiatric medication should consult a clinician before use
- Grey-market status outside the CIS; legal classification varies by country
We would rather lose the order than have you buy this blind. If any of the above is a dealbreaker, close the tab. This is not medical advice.
