What is Selank?
Plain language first. The technical label stays, but it never stands alone.Overview
Selank is a synthetic version of tuftsin, a natural immune-and-brain peptide, given as a nasal spray. In plain terms: it gently tunes the calming GABA and serotonin systems to lower anxiety without sedation or dependence.
What it's used for
A nasal spray that eases anxiety and stress while keeping you clear-headed, without the sedation or dependence of anti-anxiety pills. It is often paired with Semax.
How does Selank work?
What it does in the body, and where.Selank is a synthetic version of tuftsin, a natural peptide that sits at the junction of immune and brain signalling.
- 01It slows the breakdown of calming moleculesRather than binding a receptor directly, it appears to extend how long your own calming signals last.
- 02Anxiety falls without sedationThis is the claim that distinguishes it from benzodiazepines, and the reason for the interest.
- 03Nasal, because it would not survive injection wellSame reasoning as Semax.
- 04Almost all evidence is Russian-languageIt is a registered medicine there. The studies are largely unreplicated in Western journals.
Where this compound is thought to act.
What else is it used for?
Each group carries its own evidence level.Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.
Anxiety
Clinical use- Human trialIn 62 patients with generalised anxiety, it performed similarly to a standard benzodiazepine on three anxiety scales, with less fatigue. The study was not double-blind or placebo-controlled and reported no statistics.
- RegulatoryIt is approved in Russia as a nasal spray for generalised anxiety.
Mechanism
Early research- Lab studyIt blocks the enzymes that break down natural calming molecules, prolonging their effect.
- Animal studyIt altered BDNF activity in the rat hippocampus.
- No dataWidely repeated claims of trials in hundreds of patients do not trace to any identifiable published study.
Claims of trials in 800 patients circulate widely but do not trace to any identifiable published study. The real evidence base is one 62-patient Russian trial.
How much, and do you cycle it?
The range, and whether you take breaks.0.25 up to 0.5 mg per day, 1-2x daily. Taken in courses, usually 10 to 14 days, with breaks betweenCommunity practice
Course dosing follows the Russian clinical practice it comes from. No controlled study has compared it against continuous use.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
Selank is not injected
It is taken nasal spray.
How do you store it?
Before mixing, and after.Fridge after opening. Use within about 30 days.
Store sealed Selank in the fridge. Once opened, keep it upright in the fridge and plan to finish it inside roughly 30 days. Keep it out of light and do not freeze the liquid.

10What these words mean
Show glossary +
What these words mean
- Titrate
- Starting at a low dose and increasing it slowly over time so your body adjusts and side effects stay mild.
- Subcutaneous
- An injection just under the skin, into the fat layer, usually with a short, thin insulin needle.
- Intramuscular (IM)
- An injection into a muscle, using a longer needle.
- Reconstitution
- Mixing a powdered peptide with liquid (bacteriostatic water) so it can be drawn into a syringe.
- Bacteriostatic water
- Sterile water with a tiny amount of preservative, used to mix powdered peptides.
- Concentration
- How strong the mixed peptide is, in milligrams per milliliter (mg/mL). More water makes it weaker; less water makes it stronger.
- Units (on the syringe)
- The marks on an insulin syringe. 100 units equals 1 mL. They measure how much liquid you draw, not the dose in milligrams.
- mcg and mg
- Units of dose. 1 milligram (mg) equals 1,000 micrograms (mcg).
- GLP-1
- A natural gut hormone that lowers appetite and blood sugar. Drugs that copy it, like semaglutide, are used for weight loss.
- Growth hormone secretagogue
- A compound that nudges your body to release more of its own growth hormone, rather than injecting the hormone itself.
- Half-life
- How long a compound stays active in your body. A longer half-life means you inject less often.
- Peptide vs small molecule
- A peptide is a short chain of amino acids. A few items here (like MK-677 or methylene blue) are small molecules, not true peptides, but people use them the same way.
- Research only
- No approved dose or use in people. Sold for research and not reviewed by the FDA for safety or quality.
- Investigational
- Still being tested in clinical trials and not yet approved or legally sold for general use.
- Banned in drug-tested sport
- Prohibited by the World Anti-Doping Agency (WADA); using it can disqualify a competing athlete.
