Russian Nootropic (Selank + Semax)
Why this combination
Selank and Semax are short peptides developed in Russia, where they are used clinically as nasal sprays. Selank is derived from tuftsin and associated with anxiolytic effects; Semax is an ACTH(4-10) fragment associated with focus and neuroprotection. Stacking them aims to pair calm (Selank) with drive/focus (Semax).
Both are typically administered intranasally rather than injected. Outside Russia they are not approved drugs; figures here are community/region-specific and should be verified.
Per-compound dosing
| Compound | Dose | Frequency | Notes |
|---|---|---|---|
| Selank | 250–500 mcg | 1–2× daily (intranasal) | Often the 0.15% or 0.3% nasal solution. |
| Semax | 200–600 mcg | 1–2× daily (intranasal) | — |

Separate vials
These are usually dosed as nasal sprays measured in drops/sprays rather than reconstituted for injection, so syringe math is generally not applicable.
If supplied as a lyophilized powder for nasal solution, the reconstitution volume is chosen so each spray delivers the target microgram dose; follow the specific product's fill instructions.
Pre-blended (single vial)
Pre-blending is uncommon; the two are typically kept as separate nasal solutions and used in sequence.
Verify any blend with the reconstitution calculator before dosing — concentrations change for every compound when you alter the water volume.
Cycle length & alternatives
- Cycle length
- Often 1–2 week courses, community-dependent.
- Compared to alternatives
- Versus either peptide alone, the stack aims to balance Selank's calming profile against Semax's stimulating/focus profile. Evidence is largely regional clinical use plus anecdote.
