Frequently asked.

What is Semax?

The Semax is a synthetic heptapeptide derived from the ACTH(4-10) sequence. Extensively studied for cognitive and neuroprotective research. Sold for research use only.

How is purity verified?

Every lot of Semax is independently tested by Chromate Laboratories before release. We verify identity, purity (≥99%), and endotoxin levels. A Certificate of Analysis for your specific lot is available on request — just email admin@nxtstate.co with your order number.

How should it be stored?

All three lyophilized vials are shelf-stable at room temperature (away from direct light). Once reconstituted with sterile bacteriostatic water, vials should be refrigerated at 2-8°C and used within the standard stability window for repair research peptides.

What does each shipment include?

Each order ships with the Semax unit(s) you purchased. Reconstitution materials (bacteriostatic water, syringes, alcohol pads) are available as separate products. We recommend ordering them together if it’s your first shipment.

How fast does it ship?

Orders placed before 2pm ET ship same-day. After that, next business day. All shipments include tracking, and you’ll receive an email the moment your order is on the way. Free shipping on orders over $200.

Where is it manufactured?

Semax is compounded at facilities operating under GMP-aligned standards. We work exclusively with manufacturers who allow third-party lab verification of every batch we release.
