Noopept vs Selank
Same Russian pharmacology tradition, different jobs: Noopept was developed for cognition, Selank as an anxiolytic. Both have human data that stops well short of Western standards.
Noopept
A piracetam-analog dipeptide that raises NGF/BDNF in animals; the human data is small, single-country Russian trials — real but unreplicated to Western standards, and it's unapproved in the US.
Full Noopept evidence reviewSelank
A GABA-modulating anxiolytic that matched benzodiazepines in small Russian trials; the mechanism is credible but the evidence base is thin and single-country.

Our verdict
Neither is FDA-approved and neither has a large, blinded, placebo-controlled trial. Noopept's human record is small Russian studies in mild cognitive impairment of vascular and post-traumatic origin, run against piracetam as comparator; Selank's is small Russian studies in anxiety disorders, run against benzodiazepines and not described as randomized or blinded. Both are sold in the US as unregulated products rather than the trialed drug, and the two have never been compared with each other.
Noopept fits if
Noopept is the relevant read if cognitive symptoms and the racetam-adjacent nootropic literature are the thread you are pulling.
Selank fits if
Selank is the relevant read if anxiety is the question and you want to understand a non-benzodiazepine, GABA-modulating mechanism.
