What are nootropic peptides?

Semax is a stabilized analog of ACTH(4-10), a short piece of the stress hormone ACTH with no hormone action of its own. Rodent studies link it to higher BDNF. Selank is built on tuftsin and is studied in anxiety models and GABA signaling.

DSIP, short for delta sleep-inducing peptide, was first isolated from rabbits in deep sleep. It’s nine amino acids long and still studied in sleep and stress research.

The research behind this range is indexed on PubMed, the free database of the U.S. National Library of Medicine. Start with this PubMed search.

How to choose nootropic peptides

Match the compound to the question: Semax for BDNF, attention and memory work, Selank for stress and anxiety models, DSIP for sleep.

The Semax and Selank blend puts 5mg of each in one vial for labs that study both. Pick the nasal spray version of Semax when a protocol calls for a ready-made solution.

Nootropic peptides prices

This range has 4 products, with prices from $40.00 to $105.00. 1 of them come in more than one size or version, chosen from the menu on the product page. Shipping is free on every order, to any country we ship to.

Nootropic peptides lab testing

2 of the 4 products here have a certificate of analysis in their product photos. Most come from Freedom Diagnostics, a US lab that measures purity by HPLC and confirms identity by mass spectrometry. Each product page lists the purity results and the search code you can use to look the report up yourself.

Storage and handling

Keep sealed freeze-dried vials in the freezer at -20°C, or in the fridge if they’ll be used within a few weeks. Once a vial is mixed, it stays at 2 to 8°C and is best used within about four weeks.

Write the arrival date and, later, the mixing date on every vial or bottle. Those two dates answer most questions later.
