Summary
5-Cl-AMT (5-chloro-ฮฑ-methyltryptamine; PAL-542) combines three properties with harm-reduction implications: it is a serotonin-dopamine releasing agent, a potent 5-HT2A agonist, and an in vitro MAO-A inhibitor. Treat it as an MAOI during the session window even though clinical reversibility is not established. Start with a microtest of 0.5-1 mg to gauge sensitivity; community trials report activity at 1-2 mg and full days' worth of effects from 8-12 mg.

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track 5-Cl-AMT there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
5-Cl-AMT Source: SubstanceSearch (substancesearch.com) Oral duration: onset 0.5-1.5h ยท come-up 1-2h ยท peak 4-8h ยท offset 4-8h ยท total 9.5-19.5h ยท after-effects 12-48h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
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.
