Adamax is a disputed. N-Acetyl Semax Amidate is a semax variant.
| Comparison | Adamax ADAMAX · Semax analog | N-Acetyl Semax Amidate NA Semax Amidate · NASA Semax |
|---|---|---|
| How it works | How it works Adamax is a name first and a molecule second, so the useful question is which one a given vial holds. | How it works This is Semax with two chemical modifications, an acetyl group at one end and an amide at the other, both added to slow its breakdown. |
| What it is | A product name that covers at least two different molecules. | A longer-lasting version of Semax for focus and memory. |
| Status | Research only | Research only |
| Typical dose | 300–1000 mcg per day | 0.2–0.4 mg per day |
| How often | No established schedule | 1-2x daily |
| Stays active | Nothing published in humans | Not established |
| Dose comes from | Community practice | Community practice |
| Cycled? | No established pattern No established range | Taken in courses, usually 10 to 14 days, with breaks between Community practice |
| What it does | ||
| Drug class | Disputed | Semax variant |
| Used for | Marketed for cognition and focus by some sellers, and for growth hormone release and recovery by others. | A longer-lasting, more stable version of Semax for focus, memory, and mental clarity. |

| Numbers | ||
| Full dose line | Research only | 0.2 up to 0.4 mg per day |
| Why that cycle | No published human study establishes a schedule. | Same course pattern as Semax, which it is a longer-lasting version of. No controlled study has compared courses against continuous use. |

What separates them
Proof behind the dose. Every dose here comes from community practice. Not one is backed by a published human study, which is worth knowing before you read the numbers as if they were equivalent.
What doesn't differ: They are both taken the same way (nasal spray, or injected under the skin) and aimed at the same thing (focus & brain). Neither has a measured effect size from a published trial, so there is no number to rank them on.
What people actually report
Adamax
- Unknown, because the compound is not defined.
- Effects reported by users cannot be attributed to any specific molecule.
- Any unexpected effect, since you cannot know what produced it
N-Acetyl Semax Amidate
- Mostly mild nasal irritation from nasal use.
- Effects from injection have not been studied.
- No serious adverse events have been reported at studied doses
- Signs of an allergic reaction
Side effects are what users and trials report most often, not a complete list. Anything sudden, spreading, or breathing-related is an emergency regardless of which compound caused it.

This comparison does not cover cost, long-term safety, or how you personally will respond. Effect figures come from separate trials in different populations and are not always directly comparable to each other. Nothing here is medical advice or a recommendation to use any of these.
