N-Acetyl Selank Amidate

Cognitive & neuro Research only Animal studies

Also called NA-Selank Amidate

Selank with the same end-capping treatment: acetylated at one end, amidated at the other, to resist enzymatic breakdown. The underlying seven-amino-acid sequence and its anti-anxiety activity are unchanged.

Evidence at a glance

Evidence: Animal studies — Not yet studied in people
Status: Research compound only
Dosing: No human study has set a dose

As with the capped Semax, nearly all the supporting evidence belongs to the parent peptide rather than this modified version.

What studies report

Shares the core sequence of Selank, which reduced anxiety without sedation in Russian trials
Terminal caps slow enzymatic degradation in lab assays

How it works

Same seven-residue core as Selank, acting on GABA and serotonin signalling and on BDNF. An acetyl cap at one end and an amide at the other slow the enzymes that would otherwise break it down.
