Adamax 984 is a semax variant used for focus & brain. Adamax 984 is the form of Adamax that weighs about 984. The seller that lists it describes Semax, the Russian nootropic peptide, with an acetyl group on its starting end and two extra amino acids, alanine and glycine, on the other, and no adamantane group. In plain terms: it shares a name with Adamax 1032 but is a different molecule, and the weight on the label is the only way to tell them apart.

How much water do I add to Adamax 984?

You can reconstitute Adamax 984 with 0.5, 1, or 2 mL of bacteriostatic water. Each option produces a different concentration and syringe draw for the same dose. Use the calculator to see which is easiest to measure.

What is Adamax 984?

Plain language first. The technical label stays, but it never stands alone.

Overview

Semax with a cap on one end and two amino acids added to the other. It is sold under the Adamax name but is not the adamantane molecule, and no study has tested it.

The technical version

Adamax 984 is given by its seller as Ac-Met-Glu-His-Phe-Pro-Gly-Pro-Ala-Gly-OH, a nine-residue free acid with formula C44H61N11O13S and molecular weight about 984.1 g/mol. It is acetylated Semax extended by alanine and glycine, with no adamantane group, and so is distinct from Adamax 1032. No peer-reviewed study characterises it.

What it's used for

Sold for focus and cognition under the Adamax name, on the strength of Semax's reputation rather than any study of its own.

How does Adamax 984 work?

What it does in the body, and where.

Adamax 984 is Semax with one addition at each end, and neither is the adamantane group the Adamax name usually implies.

01
It starts from Semax
Semax is a short fragment of the stress hormone ACTH with three amino acids added to its end, studied in Russia for stroke and cognition.
02
An acetyl cap and two amino acids are added
The acetyl group covers the starting end. Alanine and glycine extend the far end, which is left as a free acid.
03
It is not Adamax 1032
The adamantane form weighs about 1032 and this one about 984. The name alone does not tell them apart, so the measured mass on a certificate of analysis is what identifies it.
04
Nothing about it has been tested
No peer-reviewed paper studies this molecule. Claims made for Adamax in general are extrapolated from Semax.

What else is it used for?

Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

How do you store it?

Before mixing, and after.

Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.

Unmixed lyophilized Adamax 984 keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.

What are the side effects and cautions?

Known cautions and warnings for this compound.

Solubility, computed: 33% charged residues, 56% hydrophobic. Water usually sufficient.

A first-pass rule from peptide manufacturers' guidance. It does not account for disulfide bridges, salt form or how the powder was dried, and it predicts what should be easy rather than what will happen in your vial.
