What are nootropic peptides?
Semax and Selank come from the Institute of Molecular Genetics in Moscow. Semax is built on a fragment of ACTH and is linked to BDNF in rodent work, while Selank is built on tuftsin and studied for anxiety through the GABA system. Our versions carry an acetyl cap and an amide end, which protect the chain from enzymes.
DSIP, delta sleep-inducing peptide, was isolated from rabbits in deep sleep in 1977. PE-22-28 is a shortened spadin analog that blocks the TREK-1 potassium channel, studied in rodent depression models.

How to choose nootropic peptides
Pick by the behavior you’re measuring: memory and focus (N-Acetyl Semax Amidate), anxiety (N-Acetyl Selank Amidate), sleep (DSIP) or mood (PE-22-28).
The capped Semax and Selank are often run side by side, since they come from the same institute and are studied with similar models.
Nootropic peptides: formats and prices
There are 4 products in this range: four freeze-dried vials. Prices run from $40.00 to $45.00. Every product page lists the amount, the format and the SKU, so you can compare like for like before you order.
Purity and testing for our nootropic peptides
Every batch in this range is checked by HPLC-MS, which measures purity and confirms the molecular weight in one test. Most products test above 99% purity, and each product page states its figure. Vials are vacuum-sealed after freeze-drying to keep air and moisture out.
Store sealed vials in the freezer at -20°C and reconstitute with sterile bacteriostatic water when you’re ready. Every vial page lists the concentration you’ll get for each volume of water. Mixed vials go in the fridge at 2 to 8°C and should be used within 28 days.
Bulk pricing on nootropic peptides
Most products here come in packs as well as single vials. Pick 2, 5, 10, 15 or 20 in the Quantity menu on the product page, and the price per unit drops by 10% to 30%. Packs ship as individual sealed vials, so you only open what you need.
