- What's the Semax price?
- £24.99 for one 10mg vial. Packs cost less per vial: 2 for £44.98, 3 for £59.98 or 5 for £87.46, which is £17.49 a vial.
- Is Semax the same as se max?
- Yes. Se max is just Semax typed as two words, and seemax or seamax peptide are common misspellings. They all mean the same seven-amino-acid peptide, MEHFPGP (CAS 80714-61-0). N-acetyl Semax amidate is a different, modified peptide.
- How fast is delivery?
- Same day, from Manchester, whenever you order. Royal Mail Tracked 24 aims for next working day delivery. Free over £40, otherwise £3.99.
- What else do I need with Semax?
- Bacteriostatic water, to dissolve the freeze-dried powder. We stock it, and you can add it from the Storage section above.
- How should I store Semax?
- Sealed vial: -20°C, away from light. Once reconstituted: 2-8°C, use within 28 days, and don't refreeze.

- Can I buy Semax in the UK?
- Yes, for laboratory research. It's a registered medicine in Russia, but in the UK it isn't a controlled drug or a licensed medicine. So it's sold for research use only, not for human use. You must be 18 or over.

About the Semax peptide
Semax is a synthetic seven-amino-acid peptide, Met-Glu-His-Phe-Pro-Gly-Pro. The first four match residues 4 to 7 of the hormone ACTH, and the Pro-Gly-Pro tail helps it resist breakdown by enzymes. It was developed at the Institute of Molecular Genetics in Moscow. We sell it as freeze-dried powder in a 10mg vial, not a nasal spray, for laboratory research only.
