    NA-Semax Amidate Dosage Guide: Protocols, Calculator & Safety

    Everything you need to know about NA-Semax Amidate dosing: protocols and safety.

    Half-Life

    ~30-45 minutes (estimated, longer than standard Semax)

    Dosage Calculator

    Calculate exact dosing for NA-Semax Amidate.

    Dosing Protocols

    Beginner

    Beginner protocol

    • Dose: 200-400 mcg/day
    • Route: Intranasal
    • Frequency: Once daily, AM
    • Duration: 14 days
    Standard

    Intermediate protocol

    • Dose: 400-800 mcg/day
    • Route: Intranasal
    • Frequency: Once or twice daily
    • Duration: 21-30 days on / 7-14 off
    Advanced

    Advanced protocol

    • Dose: 800-1,200 mcg/day
    • Route: Intranasal or SubQ (research-only)
    • Frequency: 1-2x daily
    • Duration: 30-day cycles
    • Stack with: Selank, P-21 Amidate

    Commonly Stacked With

    The amide form's longer half-life makes it a better fit for once-daily dosing. Pairs with Selank, Cerebrolysin, or Cortexin for nootropic stacks.

    Side Effects & Safety

    **Research use only - not FDA approved.** NA-Semax Amidate is a chemically modified peptide sold strictly for laboratory research. It has no approved human indication and no published human safety data for this specific N-acetyl-amidate analog. The notes below are extrapolated from the parent peptide Semax and from anecdotal user reports - not from controlled studies of this compound. **Reported / anticipated effects (mostly anecdotal, intranasal route):** - Transient nasal or throat irritation and rhinorrhea (runny nose) after intranasal dosing - Mild headache - Mild fatigue, or conversely an initial alertness/stimulation spike - Lightheadedness in some users, more likely at higher doses **Important framing:** Semax has a decades-long history of clinical use in Russia with a generally mild reported safety profile, but that record does **not** automatically transfer to this modified analog. The N-acetyl and C-amide changes alter the molecule, and its safety, long-term effects, and true duration have not been formally studied. Absence of reported serious effects here reflects absence of study, not proof of safety.

    Contraindications

    **Do not use outside of a research setting.** NA-Semax Amidate is not a medicine and has not been evaluated for human use; the points below are conservative precautions, not trial-derived medical contraindications for this compound. - **Pregnancy and lactation** - avoid; there are no reproductive or developmental safety data for this analog. - **Known peptide or Semax hypersensitivity** - discontinue immediately if any allergic or hypersensitivity reaction occurs. - **Mania or bipolar-spectrum instability** - caution; nootropic, dopaminergic-modulating peptides may theoretically aggravate activation, though this is not established for this compound. - **Concurrent CNS-active medications or stimulants** - no interaction data exist for this analog; combining is untested. These precautions are extrapolated from the parent peptide Semax and from general peptide-research safety practice, not from any published study of NA-Semax Amidate itself.
