## Description

This kit brings together everything needed to make up Semax as a metered spray for research: the peptide itself in a 10 mg vial; an empty 15 mL bottle fitted with a fine-mist pump, a dip tube and a cap; a bottle of sterile diluent that is buffered and isotonic; and some blank labels. Because it all comes in one parcel, you can set up a study of the spray format without having to find bottle, diluent and peptide separately.

Semax is a synthetic heptapeptide modelled on the ACTH(4-10) fragment — Met-Glu-His-Phe-Pro-Gly-Pro, CAS 80714-61-0, C37H51N9O10S, 813.93 g/mol. The vial holds freeze-dried powder of ≥99% HPLC purity with its lot certificate, identical to the Semax we sell on its own. Research on it covers the expression of neurotrophic factors, models of attention and memory, restricted blood flow to the brain (ischaemia) and oxidative stress.

## Frequently asked questions

### What is inside the package?

One 10 mg vial of freeze-dried Semax; one empty 15 mL spray bottle complete with metering pump, dip tube and cap; one bottle of sterile buffered diluent; and blank labels — all you need to prepare a spray solution for research and characterise it.

### How much Semax does one press release?

It depends on the volume your pump actually dispenses, which you should determine by weighing rather than reading off a data sheet. Delivered mass is that measured volume times the assayed concentration; check it again during the study.

### Does the kit come with a COA?

The Semax, yes: reverse-phase HPLC shows at least 99% purity and mass spectrometry confirms its identity, and we'll send the certificate for the vial's lot number on request. The spray bottle and the diluent are equipment and consumables, not analysed peptide.

### For how long is the made-up solution usable?

We can't give a figure — your study needs to find that out. The buffered diluent contains a preservative, but in water methionine still oxidises and peptide is still lost to surfaces. Store the bottle upright, cold and in the dark, and measure the concentration both when you start and when you finish using it.
