I got very little effects from 50mg. Perhaps the high potency was initially conjectured due to low IC50 value for serotonin release. And judging by the fact that MMDA needs a high dose and is different from MDA, I somehow doubt that adding 5-methyl group could increase potency so drastically compared to MDA (no great ring activation from additional methyl group, can't form strong interactions itself either, it's just extra bulk which seems to do for serotonin release). I would actually like to try it again and start from 100mg, if there is any psychedelic activity present, it might show up only at high doses and could still be very mild.
