Research compound, not FDA-approved

Selank is a registered Russian medicine and an American research chemical. The molecule is identical. The evidence never left Russia.

Fifty-seven selank papers are indexed in PubMed. Twenty-six are written in Russian. Exactly one carries an author affiliation outside Russia, and it is a review article rather than a study, which puts the count of original non-Russian selank research at zero. Five human studies exist, all Russian, 244 people in total, and not one of their abstracts states a dose. We counted all of it ourselves and published the script that did the counting.
