Pharmacology is presumed to involve mixed monoamine reuptake inhibition and releasing action with NET≈DAT>SERT, similar to 4-MEC but slightly less potent and longer lasting due to the ethyl para-substitution. Limited formal toxicology data exists; acute risks mirror other cathinones including tachycardia, hypertension, hyperthermia, vasoconstriction, bruxism, and potential serotonin syndrome when mixed with serotonergics. Hydration, temperature monitoring, and magnesium supplementation for jaw tension are advisable. Avoid consecutive-day use. Very little peer-reviewed data exists; all dosage and duration figures are extrapolated from seizure reports and small user samples—start with low doses.
