# Selank dosage & reconstitution (10 mg vial)

Selank dosage: calculations for a 10 mg vial use the same amounts described in the literature. Adding 2 mL of bacteriostatic water produces 5 mg/mL, so each U-100 unit contains 50 mcg.

- **Vial contents:** 10 mg Selank
- **Final volume:** 2 mL
- **Concentration:** 5 mg/mL
- **One U-100 unit:** 50 mcg in 0.01 mL

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

| 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 |

## 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.

## 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
