In plain English
NA-Semax Amidate is Semax with two small chemical caps: an acetyl group on one end and an amide on the other. These protect it from enzymes, so users describe it as stronger and longer-lasting than regular Semax at lower doses.
What it's used for
- Focus and attention
- Motivation and mental energy
- Mood
- Recovery after brain stress
Benefits
Research on the modified form is limited; its effects are expected to follow Semax, which raised BDNF and supported recovery after stroke in human studies from Russia. Users report clear, steady focus and drive.
How it works
In simple terms: it is Semax protected from breakdown.
Like Semax, it is thought to raise BDNF and influence dopamine and serotonin. The acetyl and amide caps block the enzymes that normally chew peptides from their ends.
Development history
- 1980s–1990s: Semax developed in Russia.
- 2010s: Acetylated and amidated versions appear among users.
Typical protocols
Doses vary; these ranges are what users commonly report.
| Use | Dose | Frequency | Length |
|---|---|---|---|
| Focus | 100–600 mcg | 1–2 times daily, morning and early afternoon | 1–4 weeks |
Cycling
Short courses of 1–4 weeks, then a break.
Administration options
Nasal spray is most common; subcutaneous injection is also used.
Reconstitution and dosing calculator
Usually comes in 5 mg, 10 mg or 30 mg vials, or ready-made nasal sprays. For nasal use, powder is mixed into sterile saline.

- Semax: the original, with the research.
- Adamax: another long-acting Semax variant.
Frequently asked questions
NA-Semax Amidate or Semax?
Semax has the research. The modified form is designed to last longer, and users report needing less.
