Compare these compounds
Mechanism, evidence, legal path, cost — all side-by-side.
This compound sits in research-grey territory. The caveats below carry more weight than for FDA-approved entries — read them.
Marketed primarily via grey-market vendors as a longer-acting alternative to Semax. Russian-academy modifications target peptidase resistance. Independent Western RCTs absent.
Speculative cognitive theory — no strong human trial data yet. The mechanistic logic is coherent, but effect sizes and responder rates in humans are unknown. Log onset timing, dose, and task performance specifically — not general feeling.
All Western evidence is anecdotal. Counterfeit risk for nasal-spray form is elevated. Treat as Semax with extra speculation.
N-acetyl, C-amide modified Semax sequence for protease resistance.
