What is actually in it?

Nobody has published a characterisation. It is described as a Semax derivative and that is as specific as the public information gets.

Why is it on this site at all?

Because people buy it, and a reference that only covers compounds it approves of is not much of a reference. The page exists to say plainly how little is known.

Adamax

N-Acetyl Semax Amidate variant · Adamax peptide

PreclinicalReviewed 18 Aug 2026

Adamax is sold as a Semax derivative and is the point at which this family stops being traceable. There is no published characterisation of it — no trial in any species — and no consistent account across vendors of what it actually is.

That is a different situation from the rest of this group. Semax has Russian registration. N-acetyl Semax amidate at least has a stated structure and animal work. Adamax has a name and a set of claims.

We have written this page rather than omitting it because people buy it, and a reference that only covers what it approves of is not a reference. But the honest summary is short: nobody has established what this does, and it is not clear that any two vendors are selling the same thing.

How it works

Presumed to act as Semax does, raising BDNF and affecting dopamine and serotonin systems, purely on the basis that it is described as a Semax derivative.

No independent characterisation supports that presumption, and no study in any species has tested it.

Where a compound's structure is not publicly established, mechanism cannot be reasoned about at all. Everything in this section is inference from a name.

Quick reference

Commonly described dose: 200 mcg–500 mcg
How often: Once daily
Route: Nasal
Where: Nasal
Timing: No basis for a timing recommendation.
Storage once mixed: Refrigerated, 21 days

These describe what sources report, not what you should do. Full detail and provenance in the dosing section below.

Price index

Per-milligram pricing across vendors arrives with the directory. We are recording prices now so the history exists when the page ships.

Vocabulary on this page

Evidence level: The category of human evidence behind a compound, from preclinical through to approved. Stated on every profile here as a category, not an adjective.

Regulatory status — United States

Not approved anywhere and not studied anywhere. Sold as a research chemical with no published characterisation.

Last reviewed 18 Aug 2026. Regulatory positions in this category change frequently; we date this line so you can see how current it is.

What it is studied for

Each entry states the evidence behind it. We do not rank indications by effectiveness — for most compounds here, that would be a claim nobody can support.

EvidenceNo study in any species. No published characterisation of the molecule.

Identity and clearance

Class: Described as a Semax derivative; structure not independently established

We have not stated a sequence because we could not verify one. On a page about something people put up their nose, guessing is not an option.

Dose protocols reported in sources

Displayed for reference only. Every row says where it came from, and a trial protocol and a community convention are not the same kind of information. None of this is fed into the calculator, and none of it is a recommendation.

Dose protocols reported in sources, with the source of each.
Goal	Dose	Frequency	Route	Units, 10 mg vial	Source	Start this protocol
Commonly described community protocol	200 mcg – 500 mcg	Once daily	NasalThese figures are extrapolated from Semax by people who do not know what the compound is either. There is no basis for them.	10–25 u	Community practice	Start this

Start this copies a row into a protocol of your own, which you can then edit. Where a source gave a dose range or an ambiguous frequency, those fields arrive empty — we will not pick a number on your behalf.

CheckRows marked community practice describe what people commonly do, drawn from public discussion. They are not derived from any trial and are not evidence that a dose is safe or effective.

Safety

Reported effects

EverythingCommunity practice
Unknown
No study in any species. No adverse event has ever been systematically recorded.
Overstimulation and disturbed sleepCommunity practice

When to stop

Any new neurological or psychiatric symptom.
Sleep disturbance that does not settle.
Nasal pain, bleeding or discharge.
Any allergic response: rash, hives, facial swelling or difficulty breathing. Seek urgent care.

Interactions and situations that need care

Buying it at allUse caution
There is no published characterisation of this compound, no study in any species, and no way for a buyer to establish that two vendors are selling the same substance. Every other caution on this page is downstream of that.
Any psychiatric or neurological conditionAvoid
An uncharacterised compound acting on the brain, in a brain already behaving unpredictably, has no upside worth the risk.
Pregnancy and breastfeedingAvoid
No safety data of any kind exists, for a compound whose structure has never been publicly established. There is nothing here to weigh a risk against.

What to expect

HonestlyThere is no human efficacy data for this compound, so there is no evidence-based timeline to give. Any site publishing a week-by-week schedule of expected effects has invented it.

No study exists in any species. Not a poor one. None.
The structure is not publicly established, so there is no way to know whether two vendors sell the same thing.
Dose figures in circulation are extrapolated from Semax by people who also do not know what this is.
If the Semax mechanism is what interests you, Semax itself has a clinical record and this does not.

Storage and handling

Freeze-dried powder: Refrigerated at 2–8 °C, protected from light.
After mixing: Refrigerated at 2–8 °C. Nasal solutions are handled more than injectables and are correspondingly easier to contaminate.
Long-term, frozen: Unopened powder is stable at −20 °C or colder.

Semaxcaution
Sold as a Semax derivative, so running both risks taking the same thing twice. With no established structure, even that cannot be said with confidence.

Checking your vial

Research chemicals carry no manufacturing standard, so what the vial looks like is often the only quality signal available before you use it. More on assessing quality and COAs.

Appearance establishes nothing here
For most peptides a collapsed cake reveals heat damage. Here there is no reference for what a correct vial looks like, because there is no published standard for what should be in it.

A naturally occurring copper-binding tripeptide with a long history in topical skincare research. Injected use is not what the research studied.

Ipamorelin

A selective growth hormone secretagogue that prompts a short pulse of GH release. Widely used, and supported almost entirely by early pharmacology rather than outcome trials.

CJC-1295

A GHRH analogue that raises growth hormone by amplifying the body's own release signal. Sold in two forms whose durations differ by two orders of magnitude.

This page is educational. It describes what published research reports, not what you should do. Peptides discussed here are largely not approved for human use, and nothing on Bioalmanac is medical advice. No clinician reviews these pages.
