Selank

Approved in RussiaNot banned in sport

Selank is a synthetic peptide built on tuftsin, registered in Russia as anti-anxiety nose drops and not approved by the FDA or EMA. Most studies are in animals, on anxiety, memory and immune response, with a few small studies in people. PepBank shows 19 results on Selank from 5 studies in people, and 202 from animal and lab studies. The strongest evidence is a randomized trial in people. Data as of 2026-10-30.

From the community

How people use it

What people report online. It comes from forums and guides, not from studies.

Community-reported. Not tested in trials.

Selank is a nasal drop for anxiety states that is sold without a prescription in Russia. Community sources report that people elsewhere use it as a nasal spray for anxiety and calm focus, in courses of several weeks, and some inject it.

Reported routines and cautions

What people use it for

Anxiety and stress (Russian label use; also the main community use)S1S3
Calm focus, often together with SemaxS3
Adjustment disorders and low confidence in social contact (Russian label uses)S1

Reported regimens

Regimens that community sources report for Selank. Community-reported, not tested in trials.
Context	Route	Amount	How often	How long	Agreement	Sources
Russian label, Selank 0.15% nasal drops, adultsOfficial label dosing of an approved product	intranasal drops	2 drops per nostril per dose	3 times a day	14-day course; may be repeated after 1 to 3 weeks after talking to a doctor	single source (official label text on a drug register site that also carries pharmacy order links)	S1
Anxiety and calm focus, nasal spray	intranasal spray	200 to 400 mcg per dose	2 to 3 times daily	4 to 6 weeks (S3); one month on, one month off is common (S2); 4 weeks on, 4 weeks off is common (S3)	sources differ: per-dose amount is 200 to 300 mcg in S3 and 200 to 400 mcg in S2; both give a cycle of weeks followed by a break. Both are wikis that carry seller links, and they may copy each other.	S2S3
Subcutaneous injection, used by some people instead of the spray	subcutaneous injectionS2 says it is used when the nasal spray is not available.	200 to 500 mcg per dose	once daily (S2, S3); once or twice daily (S4)	4 to 6 weeks, 5 days on and 2 days off (S3); 2 to 8 weeks on (S4)	3 sources give about 200 to 500 mcg per injection; S2 and S3 give once daily and S4 gives once or twice daily. S2 and S3 carry seller links, and the wikis may copy each other. The cycle length is given by S3 and S4 only.	S2S3S4

Reported side effects

mild stinging or irritation in the nose, nasal dryness with daily useS5
headache (mild, with higher doses)S5

Reported benefits (claims, not shown in trials)

less anxiety without sedationS3S5
no sedation or drowsiness in clinical comparisons, per one wikiS5

Cautions

The Russian label lists pregnancy, breast-feeding and age under 18 years as contraindications, because no clinical studies were done in them.S1
The Russian label says no overdose cases are recorded and that Selank does not cause drug dependence.S1
Research-grade material from outside regulated supply carries contamination, degradation and mislabeling risks.S5
A wiki notes that the FDA has raised a general immunogenicity concern for compounded peptide products; it says no immunogenicity cases from Selank were published.S5
The cycling pattern (a month on, a month off) is community-derived. The wikis differ on Russian practice: S3 says Russian clinical use does not stress cycling, and S2 says Russian courses are 14 days with one-month breaks.S2S3

Status notes

In Russia, Selank 0.15% nasal drops are sold without a prescription (label text, last change 15.07.2025).S1
Selank was not among the seven peptides the FDA Pharmacy Compounding Advisory Committee reviewed on 2026-07-23 and 2026-07-24 (BPC-157, KPV, TB-500, MOTS-c, Semax, epitalon, emideltide).S6

Gaps

All community amounts come from wiki compilations that may copy each other, and the wikis carry seller links; no first-hand forum or harm-reduction page was found. The injection amounts also rest on wikis only. The label dose is in drops; the label text read here gives no mcg per drop, and one wiki's 250 to 300 mcg 'Russian' figure was not matched to the label. FDA status for Selank was inferred from its absence in the July 2026 panel list, not from a statement about Selank. Reddit was not used.
