Summary
6-APDB (also known as 6-(2-aminopropyl)-2,3-dihydrobenzofuran or 4-Desoxy-MDA) is a stimulant and entactogenic research chemical of the phenethylamine and benzofuran classes. It is a closely related synthetic analogue of MDA and 6-APB and broadly shares the characteristics of serotonin-selective triple monoamine releasers and reuptake inhibitors associated with other entactogenic or empathogenic compounds. 6-APDB was first synthesized and studied along with 5-APDB in 1993 by David E.

Tolerance
Build-up
develops over days to weeks of regular use
Reset
3–7 days for acute; 1–3 weeks for full reset
Tolerance Decay

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.

First some notes on a prior experiences and then some notes on a particular experience, si? A chemist friend graciously tested the material by NMR and ESI-MS and found it to be an inorganic salt of 6-APDB. Prior experiences at 80 mg yielded clear ++ experiences without a strong independent character.

The powder I have is off-white/light-tan. I started this thread, posting my marquis, mecke, mandelin, simon`s and robadope tests to try to sort it out and see if someone had anything similar (thanks everyone for helping me out!), however the results were still not very clear.

hi there, it seems like 6-APDB is available now and will become even more widely available in the near future. i'll receive a sample of this compound soon and i'm wondering if anyone has already sampled it and how it compares to 6-ABP.
