Summary
Pharmacology data are scarce; in vitro transporter assays of related ฮฑ-PVP analogs suggest nanomolar NET/DAT inhibition. A 2022 forensic case reported fatal ventricular tachycardia with femoral blood 26 ng/mL, illustrating low LD50 margin. Fluorine substitution is predicted to raise metabolic stability, extending active phase relative to alkyl-only peers. User reports indicate very rapid onset when freebased (steam on foil), but subjective potency roughly half that of ฮฑ-PVP: common 'one-hit' loads are 10-15 mg, with compulsive re-hits every 10-15 min. Intranasal use burns intensely and produces drip-induced gagging; many switch to glass-pipe inhalation.
