CNS Research Peptides

Three peptides, three jobs: sharper focus, calmer baseline, better sleep. All three came out of Russian research in the 1980s and 1990s, where they were developed and used clinically, which is unusual for this category and is the reason the human dosing here is better established than for most peptides.

Semax is the focus and drive one, a modified fragment of ACTH with a tail that stops enzymes chewing it up. It is the nootropic of the three, used for mental stamina rather than stimulation. Selank is its calm counterpart, built on the same stabilised design but modelled on tuftsin, and used for anxiety without sedation. DSIP is the sleep one, a nine amino acid peptide first pulled out of rabbit blood during sleep research and used to deepen sleep rather than knock you out.

Semax and Selank are usually taken as a nasal spray rather than injected, which makes this the easiest category to start with if needles are the thing putting you off. Each product page covers how to make the spray up from the vial.

Every vial is lyophilised powder with an independent certificate of analysis, HPLC purity and mass spectrometry identity, batch-matched to the vial in your hand.
