2C-F
2C-F is an extraordinarily weak and poorly characterized phenethylamine with virtually no human activity data beyond Alexander Shulgin's personal trials documented in PiHKAL. According to PiHKAL, doses below 100 mg produce no detectable effects, while 250 mg produces only 'slight and uncertain' effects consisting of modest closed-eye visuals accompanied by lethargy. Shulgin explicitly noted that 'at no dose that was tried was there any convincing indication of believable central effects.' Published pharmacological research demonstrates markedly lower 5-HT2A receptor affinity compared to other halogenated 2C analogues, consistent with the compound's exceptional weakness. The toxicity profile, metabolism, and effects at higher doses remain completely unknown. Extreme caution is warranted given the massive doses required for even minimal psychoactive effects and the complete absence of safety data.
