Nootropic Peptides

Our nootropic peptides cover the compounds studied for memory, attention, stress and sleep: Semax, Selank, Adamax, Dihexa, DSIP and Pinealon. Many come as ready-to-use nasal sprays, since that’s how most of the research was done.

What are nootropic peptides?

Nootropic peptides are compounds studied for their effects on the brain. Semax and Selank came out of the same Moscow institute and share a Pro-Gly-Pro tail that makes them last longer. Semax is studied for memory and attention, and Selank for stress and anxiety responses. Adamax is a newer Semax analogue.

Dihexa works through a different system, hepatocyte growth factor signaling, and was developed at Washington State University. DSIP is an old sleep peptide first found in 1977, and Pinealon is the brain-linked bioregulator from St. Petersburg.

How to choose nootropic peptides

Think about delivery first. Semax, Selank and Adamax were all developed for intranasal use, so the sprays match the published research best. Vials suit studies that need a custom concentration. Dihexa comes as a spray and as capsules, since it was designed to be orally active.

For combination work, the Selank and Semax spray and the Semax, Selank and Dihexa spray put several compounds in one bottle. The REM spray combines three sleep-related peptides.

Formats and prices at a glance

This range has 13 products: eight nasal sprays, three lyophilized vials, one bioregulator vial and one capsule bottle. Prices run from $29.99 to $189.99. Every product page lists the exact amount, the format and the SKU, so you can compare like for like before you order.

Quality, testing and storage

Most of our vials carry a QR code on the label that opens the certificate of analysis for that exact batch. Check the lot number on the COA against the vial before you open it, and keep a copy with your notes.

Store lyophilized vials in the fridge, or the freezer for long periods, and let them reach room temperature before opening. Sprays go in the fridge once opened. Capsules and lotions keep on a cool, dry shelf.

Nootropic peptides FAQ

Why are so many nootropic peptides sold as sprays?

Most of the original research gave them intranasally, so a spray matches those study designs.

What’s the difference between Semax and Selank?

Semax is built on an ACTH fragment and studied for memory and attention. Selank is built on tuftsin and studied for stress responses.

What is in the REM spray?

Pinealon, Epithalon and DSIP, 10mg of each.

Are nootropic peptides for human use?

No. They’re sold for laboratory research only.
