N-Acetyl Semax Amidate dose guide

N-Acetyl Semax Amidate dosage

A modified version of Semax: acetylation and amidation are meant to slow its breakdown, for more potency and longer action per dose. No published human or animal study has tested this form, so everything else is borrowed from parent Semax. Commonly reported: a stronger, quicker hit of focus and drive than regular Semax at a smaller dose, and irritability or poor sleep at higher doses or late in the day.

Dose range

100–600 mcg (research range). Studied in research — not a recommendation.

How often

Daily: Daily, split dosing

A typical run

2–4 week cycles. Potency means many use less frequently than standard Semax. Often paired with N-Acetyl Selank, which isn't in this library.

How it’s taken

Nasal spray: Intranasal

Evidence

Emerging: Primarily preclinical / limited human data

Half-life

Expected to be longer than Semax (not measured)

N-Acetyl Semax Amidate on your syringe

Used as a nasal spray, so it’s dosed by sprays, not drawn into a syringe.
