2-PTA

Human data remain extremely limited (≤50 self-reports). Acute adverse effects recorded include marked tachycardia (>130 bpm), vasoconstriction, jaw tension, blurred vision and short-lived chest discomfort at ≥60 mg. Because the amide replaces the α-methyl, potency is roughly one-quarter of amphetamine but pressor effects are still pronounced. Neurotoxicity has not been assessed; amphetamine-like oxidative stress is plausible at high temperatures or long binges - keep body temperature <38°C and supplement antioxidants (e.g., 500 mg vitamin C). Always perform an allergy test ≤1 mg.
