Research grey

This compound sits in research-grey territory. The caveats below carry more weight than for FDA-approved entries — read them.

Mechanism

Marketed primarily via grey-market vendors as a longer-acting alternative to Semax. Russian-academy modifications target peptidase resistance. Independent Western RCTs absent.

Specifics
Focus / attentionBrain fogMood
Caveats

All Western evidence is anecdotal. Counterfeit risk for nasal-spray form is elevated. Treat as Semax with extra speculation.
