2C-TFM

2C-TFM is the most potent simple 2C analogue, with human active doses of 3-6 mg according to Trachsel and Shulgin. It rivals DOI and DOB in receptor binding affinity (Ki ≈ 75 nM at 5-HT2A/C). Because it is usually synthesized from 2C-I, retail batches from the mid-2000s were often contaminated with ~50% unreacted 2C-I, leading to mixed effects and legal complications in jurisdictions where 2C-I is prohibited. Purity must be confirmed with multi-reagent testing plus quantitative chromatography whenever possible. The compound produces an unusually clear-headed, color-saturated visual field with mild bodily stimulation and minimal vasoconstriction at doses ≤5 mg.
