Selank is a synthetic heptapeptide (seven amino acids) derived from the immune peptide tuftsin, with a Pro-Gly-Pro tail added to slow its breakdown. It has been studied mainly in Russia for anxiety and cognition. In the United States it is a research chemical, not an approved medicine.

What is Selank studied for?

Most Selank research concerns anxiety, stress responses, and nootropic (cognition and attention) effects, with additional preclinical work on neuroprotection and immune signaling. Much of the human data comes from small Russian trials. None of this establishes that Selank is safe or effective by modern regulatory standards.

Is Selank FDA-approved?

No. Selank is not approved by the U.S. FDA for any use. It is a registered prescription drug in Russia and some neighboring countries, but that approval does not apply in the United States, where it is sold only as a research chemical, not for human consumption.

Selank is not an approved drug or dietary supplement in the United States, so it cannot legally be marketed for human consumption; it is generally sold only as a research chemical. It is approved as a medicine in Russia. Laws and anti-doping rules differ by country and sport, so verify local rules and consult a licensed professional.

How is Selank different from a benzodiazepine?

Some studies suggest Selank may influence the GABA system indirectly (for example through allosteric effects and by slowing enkephalin breakdown) rather than binding the benzodiazepine site directly, and Russian trials reported anxiolytic effects without the sedation or dependence typical of benzodiazepines. This comparison comes from limited research and does not make Selank a proven or interchangeable treatment.

What are the reported side effects of Selank?

Human safety data are limited because rigorous modern trials are lacking. Russian studies reported it was generally well tolerated, with relatively few effects. Long-term safety is unknown, research-chemical purity is not guaranteed, and contamination during handling can cause infection. Speak with a licensed clinician before considering it.

How is Selank dosed in research settings?

There is no validated human dose recognized outside its Russian approval, and WikiPeps does not publish dosing protocols. Any decision about quantity, route, or frequency is a medical decision that belongs with a licensed clinician who knows your history.

Selank dosage

Selank comes in 10 mg vials. Pick your vial to see exactly how much bacteriostatic water to add and how many insulin units to draw. Reconstitution math and unit conversions for the 10 mg vial. Selank's on-record dosing is intranasal (Russian clinical use); it is not FDA-approved and has no validated injectable dose.

Enter the mg on your Selank vial, the bacteriostatic water you added, and your target dose — it works out the exact units to draw on a U-100 insulin syringe, for whatever you personally have.

Check the decimal. A misplaced decimal point here is a 10× dosing error. Re-read every number, and confirm your dose with a licensed clinician before you draw.

Educational only — not a dosing recommendation. This tool does the measurement math; it does not tell you what to take. On a U-100 insulin syringe, 100 units = 1 mL.

Reconstitution figures are deterministic measurement math. WikiPeps is a community reference and sells injection supplies only — never peptides. Nothing here is medical advice.
