Nasal Spray DIY Kit (Semax 10 mg · Spray Bottle · Solution)
Semax 10 mg vial, 15 mL metered spray bottle and buffered diluent in one kit
- Research areasIntranasal delivery characterisation, spray plume and droplet-size work, aqueous peptide stability, BDNF/NGF expression and cognition models
Overview
This kit pairs a 10 mg vial of Semax with the hardware needed to prepare and study it as a metered spray: one 15 mL fine-mist spray bottle with pump, dip tube and protective cap, a bottle of sterile buffered isotonic diluent, and blank labels. Everything arrives in one package, so a spray-format study can be set up without sourcing bottle, diluent and peptide separately.
Semax is a synthetic heptapeptide based on the ACTH(4-10) fragment, sequence Met-Glu-His-Phe-Pro-Gly-Pro, CAS 80714-61-0, molecular formula C37H51N9O10S, molecular weight 813.93 g/mol. Supplied here as ≥99% HPLC-purity lyophilized powder with a lot-matched certificate of analysis, it is the same material as our standalone Semax vials, and it appears in the literature on neurotrophic factor expression, attention and memory models, cerebral ischaemia and oxidative stress.

Working out the concentration
A lyophilized vial carries a mass on the label and no concentration anywhere, so the first calculation of any protocol is the reconstitution one. The peptide concentration calculator converts vial mass plus diluent volume into mg/mL, and back into the draw volume for a given mass.
Certificate of analysis
Every lot of Nasal Spray DIY Kit (Semax 10 mg · Spray Bottle · Solution) is released against a certificate of analysis: the batch-specific laboratory data for that lot, not a generic document for the compound. The lot number on the certificate matches the lot number printed on the label you receive — the vial label itself, where the product is vialled — so the record and the material it describes can always be reconciled.
Peptide purity: ≥99% by HPLC — the specification for this listing. The figure for the lot you receive is the one reported on that lot’s certificate.
No lot certificate is on display on this page at the moment. That is a publishing state and not a testing one: lots are released and documented as described above whether or not the document is posted here, and we will send what exists for the lot in stock, or for a lot already on your bench, by its number.
Certificates are available on request before you order as well as after, with no account and no charge. Request the certificate for this listing, read the testing and documentation policy in full, or see how to read a peptide COA.
Questions about Nasal Spray DIY Kit (Semax 10 mg · Spray Bottle · Solution)
What is in the kit?
One 10 mg lyophilized Semax vial, one empty 15 mL metered spray bottle with pump, dip tube and cap, one bottle of sterile buffered diluent, and blank labels. It is everything needed to prepare and characterise a spray-format research solution in a single package.
How much peptide does each spray deliver?
That depends on the volume the pump actually delivers per actuation, which should be measured gravimetrically rather than taken from a specification sheet. Multiply the measured volume by the assayed concentration to obtain delivered mass, and re-check it across the study window.
Is a certificate of analysis included?
The Semax supplied in the kit is analysed by reverse-phase HPLC to ≥99% purity with mass-spectrometric identity confirmation, and a lot-matched COA is available on request against the vial's lot number. The bottle and diluent are hardware and consumables, not analysed peptide.
How long is the prepared solution good for?
That is an empirical question for the study to answer, not a figure we can state. The buffered diluent is preserved, but methionine oxidation and adsorption losses both proceed in aqueous solution. Keep the bottle cold, dark and upright, and assay at the start and end of the working period.
