I've tried 5-EAPB as an alternative to other euphoric stimulants over the last few years. I loved MDPV, but it's way too long. MDMA is its own wonderful, but the crash and hangover is harsh. 5-MAPB is a great in between.

Tolerance Decay
Full tolerance

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.
Tolerance data for 5โEAPB is not formally studied; model reflects community practice with MDMAโlike releasers: marked acute tolerance after one strong session, partial recovery after ~1โ2 weeks, closer to baseline by ~4โ6 weeks. Confidence low; individual variability high.

Iยm writing this on the Tuesday after the Saturday I took it. Iยm a 20 year old 165 pound male attending college. Iยve used empathogens of various kinds (n-ethylhexedrone, kanna, MDMA, 5-MAPB) before, but I hadnยt used any empathogens or serotonin-releasing substances in over a month (I think at least six weeks) before...

5-EAPB/ 200mg - Pioneering - The names Shepard, Alan Shepard. 1-(benzofuran-5-yl)-N-ethylpropan-2-amine 5-EAPB, 200mg in water. Oral consumption. Feel free to skip top paragraphs, TL;DR - no tolerance, no supplements, no medication. The rest is thorough description.
mad apologies. 17.00 6 lads, 5eapb dropped 135mg each all first time. mad wave begins. 17:30- slow heart pulsations evidence of drowsiness student 1 18.00-Mad come up large sensations of clarity and slight orgasmic feelings. 1 is still fucked in the corner experiencing emotional breakdown.
I bought 120mg pellets from a UK vendor who according to safeorscam.com has good reputation. I would like my body to have been a clean slate but the day before and the day before that I had a small dose of 0.75mg DOI each day, just for the speedy rush of it.
Background, had been chilling with some EPH and low dose 5-EAPB all day, theres a TR or that to but its a shit read. Now, i had allowed both chems to virtually leave my system and decided that it was a good idea to dose again with the 5.
This RC came as a free gift with my purchase so I thought I'd give it a go. Man was I in for a ride! Not totally unpleasant but definitely not pleasant. I could not keep my thoughts together it felt very disconnected. Could not sleep if I wanted to. Also the jaw clenching is the worst I've ever had.
