Semax + Selank
The Russian nootropic pair: focus plus calm, without sedation.
Why this stack
Semax and Selank come out of the same Russian peptide research tradition and get stacked because they cover opposite halves of cognition. Semax is the stimulation side: focus, memory and BDNF-related signalling. Selank is the anxiolytic side: it takes the edge off through GABA and serotonin modulation without sedating. The community treats the pair as a balanced daily driver, injected or as nasal sprays.
The protocol at a glance

| Compound | Dose | Frequency | Recon | Units/injection |
|---|---|---|---|---|
| Semax Human trial data |
800 mcg | Once daily | 10 mg + 1 mL | 8 units (0.08 mL) |
| Selank Human trial data |
500 mcg | Once daily, 4 weeks on / 4 weeks off | 5 mg + 0.5 mL | 5 units (0.05 mL) |
How it is run
- Once daily each, commonly in the morning; both also exist as nasal sprays with the same split.
- Cycled 4 weeks on, 4 weeks off, rather than run continuously.
- The combined vial doses refer to each component.

Track this stack
The free tracker logs each component on its own schedule, rotates injection sites across the whole stack, and counts down every vial with a reorder heads-up.
Sourcing the stack
Same rule as every protocol page: the batch COA matters more than the price. Summit Research Supply is the supplier we feature; code PEPDOSE applies to each component.
