| Attribute | Semax/Selank Blend | N-Acetyl-Semax |
|---|---|---|
| Category | Nootropics | Cognitive |
| Research Stage | Preclinical (no trials on the blend; components studied separately, mostly in Russia) | Duplicate entry - see NA-Semax |
| Mechanism of Action | The Semax/Selank blend combines two synthetic Russian-developed regulatory heptapeptides, dosed together (usually intranasally) to pair an activating, pro-cognitive peptide with a calming, anxiolytic one. Because the blend itself has never been studied, its… | See the full guide This page is a duplicate of NA-Semax, which is the canonical, maintained entry.

| Half-Life | Both component peptides have short plasma half-lives (on the order of minutes) but a prolonged duration of central action, attributed to the protective C-terminal Pro-Gly-Pro sequence they share. Blend-specific pharmacokinetics have not been characterized. | — |
| Typical Dose Range | Semax ~250-600 mcg + Selank ~250-300 mcg per day, intranasal (community-reported; no established blend dose) | — |
| Dosing Frequency | Once or twice daily, intranasal (community practice; no validated schedule for the blend) | — |
| Administration | — | — |
| Side Effects | Reported side effects are drawn from single-component use, since the blend itself has not been studied. Intranasal administration can cause nasal or throat irritation and mild headache. The Semax component may, at higher doses, cause over-stimulation,… | — |

Semax/Selank Blend: potential benefits
- Focus, clarity, and verbal fluency attributed to the Semax component (linked to BDNF/TrkB neurotrophic signaling in preclinical studies)
- Calming, anti-anxiety effects attributed to the Selank component (a GABA-modulating, anxiolytic peptide in animal and limited clinical studies)
- 'Calm focus' - the community rationale of pairing an activating peptide with an anxiolytic one to get drive without jitters
- Anecdotal stress resilience and mood support
- Reported memory and learning support (component-level preclinical signals only; not demonstrated for the blend)
N-Acetyl-Semax: potential benefits

Which has the longer half-life, Semax/Selank Blend or N-Acetyl-Semax?
Semax/Selank Blend has a half-life of Both component peptides have short plasma half-lives (on the order of minutes) but a prolonged duration of central action, attributed to the protective C-terminal Pro-Gly-Pro sequence they share. Blend-specific pharmacokinetics have not been characterized.. N-Acetyl-Semax has a half-life of not reported. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Can you stack Semax/Selank Blend and N-Acetyl-Semax?
