Semax 10mg

Semax is a synthetic heptapeptide derived from ACTH(4-10), commonly classified within cognitive and neuropeptide research alongside neurotrophic signalling, BDNF expression, and central nervous system research. (!) Learn more in our Semax peptide guide view here.

N-Acetyl Semax Amidate — often shortened to NASA — is a modified form of Semax carrying an acetyl group at one end and an amide at the other. Those modifications change its stability profile, so it is a distinct compound rather than a different label for the same thing. PhaseOne supplies standard Semax.

They share the same core sequence but are not interchangeable — the acetyl and amide modifications alter how the molecule behaves, and research using one does not automatically transfer to the other. Listings sometimes blur the two, so it is worth confirming which form a supplier is selling. PhaseOne stocks standard Semax.

Both are short peptides from Russian research programmes and are frequently discussed together, but they are structurally unrelated — Semax derives from ACTH(4-10), Selank from tuftsin. Their studied pathways differ accordingly, so findings on one do not transfer to the other. PhaseOne stocks both as separate 10mg vials — see Selank 10mg.

PhaseOne ships Semax Australia-wide for research use, dispatched locally with tracking, in 10mg vials. Every vial carries a batch-specific Certificate of Analysis verifying ≥99% HPLC purity.

Yes — PhaseOne has Semax peptide for sale online in 10mg vials, shipped Australia-wide. Semax listings vary in which form they contain, since the standard peptide and the N-Acetyl Amidate modification are different compounds. PhaseOne supplies standard Semax as a lyophilised research powder with a batch Certificate of Analysis.

PhaseOne prices Semax at A$59.99 for a 10mg vial, with the batch Certificate of Analysis included at no extra cost. Current pricing is shown on this page.

No. Semax is not registered on the ARTG and is not approved for supply as a medicine in Australia, so Chemist Warehouse and other Australian chemists do not stock it. It is supplied as a research compound through research suppliers instead.

Published Semax research has examined its relationship with BDNF and NGF expression, central nervous system signalling, and neuroprotective pathways, with origins in Russian clinical research dating back several decades. Semax remains a closely watched compound within Australian cognitive and neuropeptide research communities, as additional laboratory findings continue to emerge.

Semax is supplied as a lyophilised powder for improved stability during storage and shipping across Australia. Unreconstituted vials should be kept refrigerated and protected from direct light, and are commonly reconstituted using bacteriostatic water prior to research preparation. (!)

As interest in research peptides grows across Australia, transparency and third-party testing have become increasingly important to Australian peptide buyers. All PhaseOne research peptides are supported by third-party HPLC testing, verified COA reporting, research-grade manufacturing standards, and Australia-wide access. (!) View our COA library.

HPLC testing refers to High Performance Liquid Chromatography, an analytical method used to verify peptide purity and compound identity - a standard PhaseOne applies to every research peptide sold in Australia.

Yes - Semax is frequently studied within the same broader cognitive and neuropeptide research category as other neurotrophic and central nervous system-focused compounds, most often alongside Selank. (!) View our Semax peptide guide view here.
