Selank
Also known as TP-7
Anxiolytic peptide analogue of tuftsin.
Medical status: Approved in Russia as an anti-anxiety medication.
Also commonly used for (off-label)
- Everyday anxiety and stress
- Calm focus without sedation
Off-label and research uses are what people report, not approved indications. Talk to a clinician before using any of them.
How it's taken
sprayed into the nose and absorbed through the nasal lining — no needles
a small shot into the fat just under the skin (belly, thigh, or love handle)
Availability varies by supplier — injectable is the most commonly researched form.

- Documented dose
- 250–500 mcg
- Typical frequency
- Once daily for focus; twice daily (morning and afternoon) for anxiety
- Cycle

- Regulatory status
- Approved in Russia only; unapproved elsewhere.
Dose on a U-100 syringe (250–500 mcg)
| Vial | BAC water | Draw |
|---|---|---|
| 5 mg | 2.5 mL | 13–25 units |
| 5 mg | 3 mL | 15–30 units |
| 10 mg | 2.5 mL | 6.3–13 units |
| 10 mg | 3 mL | 7.5–15 units |
On a U-100 syringe, 100 units = 1 mL, and the syringe holds 100 units total. Most people keep a single subcutaneous injection under about 50 units — bigger volumes are usually mixed stronger (less water) or split into two shots. Only mixes that fit in one syringe are shown. Always double-check with the reconstitution calculator.
What it does
A peptide developed from a natural immune fragment (tuftsin) and used in Russia for anxiety. It nudges GABA and serotonin activity and raises BDNF, a growth factor for brain cells — calming without sedation or dependence. What people look into it for: • Everyday anxiety and stress without feeling drowsy or foggy • Clearer thinking and better focus under pressure • Steadier mood and better stress resilience • Sleep quality in people whose sleep is disrupted by worry It is usually taken as a nasal spray. Human research exists but is mostly Russian and small.
Mechanism
Modulates GABA and enkephalin systems and raises BDNF.
Storage — lyophilisedwhat's this?
Refrigerate 2-8C, protect from light.
Storage — reconstitutedwhat's this?
Refrigerate 2-8C, use within ~28 days.
Reconstitution noteswhat's this?
Common mix: 5 mg vial + 2.5 ml bacteriostatic water = 20 mcg per unit, so 250 mcg is about 6 units and 500 mcg is about 11 units. Nasal sprays are the other common route and act faster.
Stacks well with
- SemaxThe classic Russian nootropic pair — Selank calms, Semax sharpens focus.
- BPC-157Added for neuro-repair and stress-related inflammation.
Popular combinations reported in the community and research literature — not a recommendation. Adding peptides multiplies side-effect risk; check with a clinician.
Commonly reported side effects
- Nasal irritation
- Drowsiness
- Headache
Contraindications noted
- Pregnancy or breastfeeding
Research notes
Russian clinical use; limited peer-reviewed Western data.
