Xeno Laboratories Semax 5 mg/ml Nasal Peptide Research Vial

Semax is a synthetic heptapeptide with the sequence Met-Glu-His-Phe-Pro-Gly-Pro and is described in the literature as an analogue of the ACTH(4-10) fragment. Its chemistry is C37H51N9O10S with a mass of 813.93 g/mol and CAS number 80714-61-0. It is supplied as laboratory reference material, not as a medicine.

The bulk of the published work is animal behavioural testing paired with biochemical markers, plus cell culture experiments on peptide stability. Researchers commonly measure messenger RNA levels for neurotrophic markers after exposure and compare them with a control group. Cell culture and rodent results are not clinical results, and the studies are small and few in number, so the field describes the mechanism as open rather than settled.

Keep the material cold and protected from light, and above all avoid repeated freeze-thaw cycles, because that is the usual way a working peptide solution loses potency. Aliquoting a volume into single-use portions before freezing removes the problem. Check the physical form stated on the product block, since a material already in solution is handled differently from a lyophilized powder that needs a diluent added.

It is registered as a prescription medicine in Russia, where it was developed, and outside that market it is sold as a research peptide rather than an approved drug. The sources provide no human pharmacokinetic profile, no agreed half-life and no long-term safety data, and this vial is laboratory material rather than the Russian pharmaceutical product. A research listing is not a licence and not a medical claim.

The peptide is not named individually on the list as this card read it, but that is an absence of a named entry rather than a clearance, and laboratories should treat a general class entry, the current list edition and the relevant federation rules as the deciding documents. An athlete under testing should never infer permission from an unlisted name, since the list is revised and classes are worded broadly.

Human safety reporting for this peptide is thin. Accounts of the Russian nasal pharmaceutical form describe local nasal irritation, headache and excitation or insomnia in some users, managed by adjusting or stopping use, and the sources state that no long-term safety data exists. That is not a safety assessment of research-grade material, and the animal findings should not be read as one.

Yes, this 5 mg/ml presentation is listed with international checkout and a U.S. domestic shipping option, and each batch carries an HPLC report and a Certificate of Analysis. Orders are handled within one to two business days. Stock, pack and the current price are shown in the product block above, so confirm the availability line before ordering rather than assuming a dispatch time.
