What it actually is
Adamax is sold as a designer analogue of Semax, the Russian nootropic built from a fragment of the hormone ACTH. It is described as Semax with the end modifications of P021: an acetyl cap on the front and an adamantane-bearing glycine on the back. In P021, a lab compound derived from the neurotrophic factor CNTF, that adamantane piece was added to help it cross the blood-brain barrier and resist enzymes. That is where the name comes from.
The clearest official mention is from New Zealand's Medsafe, which in June 2025 named Adamax next to Semax as ACTH analogues being imported by individuals, and proposed making the whole group prescription-only. The classification committee deferred that decision in July 2025; Medsafe has since repeated its recommendation.
How it’s thought to work
- Claimed: Semax-like effects — Sold on the same promise as Semax: more BDNF, new neurons, sharper focus. Medsafe's summary of this whole group is that the mechanism is often unknown.
- Claimed: better stability — The end caps are meant to stop enzymes breaking it down and help it reach the brain. That was the design intention for P021, a compound tested in mice. For Adamax nobody has measured whether it holds.
- Claimed: stronger and longer — Sellers say it outlasts Semax. No pharmacokinetic data have been published to check that against.
- Actual mechanism — Unknown. A modified molecule can bind more strongly, less strongly or differently from its parent, and nobody has published which.
What the research says
There is nothing to summarise. A PubMed search for Adamax returns papers about a machine-learning optimiser with the same name; there is no peer-reviewed paper on the peptide, no entry in PubChem and no study on ClinicalTrials.gov (all checked 15 Oct 2026). The parent compound Semax has its own Russian research base, and P021 has mouse data from a US lab. Neither tells you what this particular molecule does in a person.
- Zero peer-reviewed studies on the Adamax peptide on PubMed.
- No PubChem record and no registered clinical trials.
- Named by NZ Medsafe (June 2025) as an ACTH analogue being imported; prescription-only status proposed, decision deferred.
- Every effect claim is extrapolated from Semax or P021.
Reported protocols
These are the doses the peptide community actually reports running (Reddit & forums), alongside published research — logged for education, not as a recommendation to use.
| Parameter | Commonly reported range |
|---|---|
| Community dose | Not established. The only dose figures online come from sellers and seller-linked guides, and they do not agree with each other. With no human data and no independent reports to check them against, there is no honest number to give. |
| Route | Not established. No study has measured how much reaches the blood or the brain by any route. |
| Why Semax doses do not transfer | The point of the modifications is to change how the molecule behaves. If they work, Semax numbers are wrong for Adamax; if they do not, there is no reason to choose it. |
| Community tip | When you see a confident Adamax protocol, ask where it came from. So far the trail ends at a seller. |
Common use cases
| Goal | Community protocol notes |
|---|---|
| Research only | no human use has evidence behind it |
| If it is the Semax effect you are after | Semax itself has far more published data than its modified cousin |
Mixing it (reconstitution)
Freeze-dried peptides must be reconstituted with bacteriostatic water before they can be measured. Carl’s calculator turns “mg in the vial + ml of water + target dose” into “units on the syringe” — and tells you how long the vial lasts.

Injection & handling
There is no established route or dose to describe. No study has looked at how much of it reaches the bloodstream or the brain, by nose, under the skin or any other way, so there is nothing here to follow. Anything drawn from an unregulated vial also carries the usual sterility and contamination risks, on top of the unknowns about the molecule itself.
Stacks it appears in
- Instead of Semax — The usual pitch is as an upgrade. There is no head-to-head data, so in practice it is a swap from a studied molecule to an unstudied one.
- With Selank — Sold in the same nootropic bundles as Selank and Semax. There is no data on the combination.
