Selank: what it is, what the evidence says, and its real status
A nootropic peptide studied for calm and anxiety support.
Short version: Semax's calmer sibling, studied for calm and anxiety. Same honest position, interesting, under-evidenced for our bar, education only.
Can you actually get it?
Plain-English verdict: Education only.
Regulatory status: Education only · Not on PCAC agenda.
Not offered. Not on the PCAC agenda and below our evidence bar for an offer, it lives here purely as education.
