What Semax is

Semax is a synthetic seven-amino-acid peptide developed in Russia from a fragment of adrenocorticotropic hormone (ACTH 4-10), with a Pro-Gly-Pro sequence added, and designed to have no hormonal activity. It is registered in Russia as a prescription nasal drop for cognitive and cerebrovascular conditions, but its clinical evidence comes from small Russian studies, and it is not approved in the UK, US, Canada, Australia or New Zealand.

Before you choose a Semax supplier

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.

For what Semax is and what published studies have found, see our Semax guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in Australia? and see all suppliers serving Australia.

Checking a Semax certificate of analysis

  1. The certificate names a laboratory you can find independently, and ideally one with no stake in the result.
  2. It carries a batch or lot number that matches the product page or the vial label, and a test date.
  3. It confirms identity by mass spectrometry, not only purity by HPLC. Purity alone does not show the vial contains Semax.
  4. It includes the chromatogram and mass spectrum, not just a summary table.
  5. Where the laboratory offers online verification of its reports, the report number checks out.

Red flags

  • No certificates at all, or certificates available only “on request”.
  • The same certificate used for several products or several years of stock.
  • Payment only by cryptocurrency or bank transfer, with a discount for paying that way.
  • A price far below every other supplier on this page.
  • No company name, address or way to contact the business other than a web form.
  • Vials labelled only with a code rather than the product name and strength.

How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.

Vials, capsules and pre-mixed products

Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.

Semax in Australia: questions

Where can I buy Semax in Australia?

12 of the suppliers PepFinder tracks list Semax and are based in or ship to Australia. The highest rated are Aussie Peptide Hub, EVO Research Australia, Pureform Peptides. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews; nobody pays to be included or to rank higher.

How much does Semax cost in Australia?

Listed prices in AUD run from A$4.16/mg to A$13.00/mg, median A$7.90/mg, across 17 listings from 11 suppliers. Compare price per mg rather than price per vial, and only within one currency; a price far below the rest is more often a warning than a bargain.

What sizes is Semax sold in?

Suppliers on this page list Semax in 5mg, 10mg, 11mg, 11mg Vial, 11mg Vial + BAC Water 3ml, 30mg. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.

Is it legal to buy Semax in Australia?

Most common research peptides, including BPC-157, TB-500, ipamorelin and CJC-1295, are prescription-only (Schedule 4) in Australia, and the TGA says research-use-only disclaimers do not make their supply lawful. Our page on whether peptides are legal in Australia sets out the rules with a link to every source. This is general information, not legal advice.

Can Semax be shipped to Australia?

Importing a prescription-only medicine, including by post, needs a valid Australian prescription at the time of import; imports without one are seized, and unlabelled or code-only vials are destroyed. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.

How do I check a Semax supplier's test results?

Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for Semax from these suppliers, so check each supplier's own site.

How this list is built: suppliers appear because they list Semax on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
