Summary
Human data remain extremely limited (โค50 self-reports). Acute adverse effects recorded include marked tachycardia (>130 bpm), vasoconstriction, jaw tension, blurred vision and short-lived chest discomfort at โฅ60 mg. Because the amide replaces the ฮฑ-methyl, potency is roughly one-quarter of amphetamine but pressor effects are still pronounced.

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 2-PTA there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
2-PTA Source: SubstanceSearch (substancesearch.com) Oral dose (mg): light 10-20 ยท common 20-40 ยท strong 40-80 ยท heavy 80+ Insufflated dose (mg): threshold 2 Sublingual dose (mg): threshold 5 ยท light 10-20 ยท common 20-40 ยท strong 40-80 ยท heavy 80+ Oral duration: onset 10-25m ยท peak 0.75-1.5h ยท offset 0.5-1h ยท total 1-3h ยท after-effects 1-6h Insufflated duration: onset 2-8m ยท peak 0.75-1.5h ยท offset 0.5-1h ยท total 1-3h ยท after-effects 1-6h Sublingual duration: onset 10-25m ยท peak 0.75-1.5h ยท offset 0.5-1h ยท total 1-3h ยท after-effects 1-6h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 30 mg (Oral).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session โ the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
