Research grey

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

Mechanism

1-(4-methoxybenzoyl)-2-pyrrolidinone. The fat-soluble structure means it crosses BBB faster than piracetam and enables mood/anxiolytic effects piracetam lacks. AMPA-receptor positive modulation reduces receptor desensitization. Italian-developed (1979) Roche compound. Short half-life (1-2.5 hr) means split-dose protocols are the norm. Active metabolites (anisic acid + anisoyl-GABA) extend the effective window.

Field reports

Distilled themes from named communities — Reddit threads, forums, creator commentary. Not direct quotes; not clinical evidence. Useful for calibrating expectations against what real self-experimenters report.

r/Nootropics + r/Anxiety nootropic-aware threads

Cohort consensus: subjectively warmer than piracetam — mood + verbal-fluency lift more noticeable than raw cognitive performance. Stacks well with caffeine + L-theanine.

Caveats

Choline pairing reduces headache risk same as piracetam. Mild GI upset at high doses. Anxiety paradoxically worsens in some sensitive users — start at 750 mg before titrating. Stack with phenibut amplifies GABAergic burden — not recommended.

Evidence levelEmerging
Regulatory statusNot FDA-approved in US — same gray zone as piracetam. Prescription (Draganon, Sarpul) in some EU countries; OTC in LATAM.
DNA / pharmacogenomicsLow — Hepatic CYP2C9 + CYP3A4 metabolism — interaction theoretical with strong inducers/inhibitors.
