Selank Dosage Chart (10 mg vial)
No published clinical trial establishes a dosing regimen for Selank. Any figure circulating as a human protocol does not come from an indexed trial. This site does not publish doses without a verifiable source.
U-100 Conversion Table (2 mL = 5 mg/mL)
| U-100 units | Volume | Contains | Yield per vial |
|---|---|---|---|
| 2 | 0.02 mL | 100 mcg | 100 injections |
| 5 | 0.05 mL | 250 mcg | 40 injections |
| 10 | 0.10 mL | 500 mcg | 20 injections |
| 20 | 0.20 mL | 1 mg (1000 mcg) | 10 injections |
| 30 | 0.30 mL | 1.5 mg (1500 mcg) | 6 injections |
| 50 | 0.50 mL | 2.5 mg (2500 mcg) | 4 injections |
| 100 | 1.00 mL | 5 mg (5000 mcg) | 2 injections |
Reconstitution Steps
- Draw 2 mL of bacteriostatic water with a sterile syringe.1
- Inject slowly down the vial wall; avoid shaking to prevent foaming.2
- Gently swirl or roll until fully dissolved (clear solution).3
- Label with the reconstitution date and refrigerate at 2–8 °C, protected from light; use within 4 weeks.4
Supplies Needed
Per 10 mg vial: 2 mL of bacteriostatic water, one U-100 syringe per injection (plus one to reconstitute) and two alcohol swabs per injection.

Selank Vial and Research Context
- Reconstitute: add 2 mL of bacteriostatic water to produce 5 mg/mL.
- Easy measuring: 1 U-100 unit = 0.01 mL = 50 mcg.
- Vial size: the 10 mg label is total nominal content, not a per-injection amount.
Storage Instructions
- Lyophilized (unopened): −20 °C for long-term storage; 2–8 °C if used within weeks. Protected from light.
- Reconstituted: 2–8 °C, do not freeze. Use within the documented period (typically up to 4 weeks with bacteriostatic water).
- Handling: do not shake; avoid temperature cycling; label with date and concentration.
- Discard: cloudy solutions, particulates or expired preparations are discarded.
More detail in the storage guide (Spanish).
Important Notes
- Research only: the referenced compounds are sold for laboratory research. Nothing here is medical advice or an administration schedule.
- Above 100 units: a 1 mL U-100 syringe cannot hold them; split across syringes or reconstitute with less volume.
- Accuracy: concentration depends on the actual volume added; measure the diluent with a syringe, not by eye.
- Verification: confirm vial contents against the batch certificate of analysis before calculating.
How This Works
- Modulación GABAérgica: increases the sensitivity of GABA-A receptors without acting as a direct agonist, which explains its anxiolytic effect without sedation
- Regulación de serotonina y dopamina: balances both neurotransmitters in limbic regions associated with stress
- Inmunomodulación: retains the parent tuftsin's properties on macrophage activation and immune response
- Aumento de encefalinas: protects endogenous opioids from degradation, improving the stress tolerance threshold
- Modulación de BDNF: neurotrophic effect complementary to that of Semax
Research Applications
- Trastorno de ansiedad generalizada
- Chronic stress and functional adrenal exhaustion
- Sleep disorders associated with anxiety
- Premenstrual syndrome
- Addiction recovery (especially alcohol and opioids)
- Immune system support under sustained stress
Precautions Described in the Literature
Excellent safety profile. No documented addictive potential. No withdrawal syndrome. Local injection site reactions or mild nasal irritation are the most common adverse events.
Studied Combinations
- Cognition + stability: Selank + Semax (combinación clásica)
- Sleep + anxiety: Selank + DSIP
- Estrés crónico: Selank + NAD+ for additional energy support
Injection Technique in Research
- Route in the studies: subcutaneous, in abdominal or thigh adipose tissue, rotating the site.
- Syringe: 1 mL U-100 (100 units); read in units, not mL.
- Asepsis: alcohol swab on the stopper and the site; a new syringe per injection.
- Drawing: purge air, draw the units from the chart and verify before withdrawing the needle from the vial.
