Just an update, I hadn't dipped into it since my last report. I mixed it with 3-MMC. 250mg 3MMC and 200mg 4BMC. I was wondering if the more serotoningeric quality might mix with the 3-MMC to produce something 4-MMC like in effect. I was right, and, I dosed way too high. The too potentiate each other. However, though I wasn't seeking it, I had a very euphoric high, that lasted about 90 minutes to two hours. About 4 hours after the first dose I did it again, partly because I was curious if there was a quick tolerance build up, and partly I just wanted to make sure that was really the combo I had put together and I hadn't;t made an error. The second high was identical to the first. Even nystagmus, which I haven't had off a cathinone since pre ban meph. Quite happy it's in my stash now. Did another dose a few hours later. Same effect, and by this time I was expecting a crash. None came. Without 3-MMC - I would compare 4-BMC most closely to MDAI, if anyone remembers it. It too was useful to mix with things. Used to go great with MPA. Like a little less toxic version of MDMA, that also had no crash.
