4-Me-NEB

User reports are highly variable: some batches appear largely inert below 100mg, while others enable prolonged wakefulness (48+ hours) with minimal euphoria but strong goal-directed focus, suggesting functional/ADHD-medication-like properties. Very limited human pharmacology data exists. Detected in Japanese forensic surveys of "dangerous drug" herbal blends. Analytical reference standards available from Cayman Chemical at ≥98% purity.
