I've tried 2/3FEA pellets. I think it makes no sense to redose on this if you want to make it more intense, it just prolongs the experience and its boring residual stimulation (after the "comedown", so to speak). If you redose, it less than an hour after dosing the first dose..
I tried it 4 times, first time was pretty cool, and very rushy, with the 70/30 pellets, other times was quite uneventful, but nice. Last time I dosed half of a 125/50 pill, so around 62.5/25, it was strangely less potent than the 70/30 pills... so I don't know what to think about it, maybe I have a progressively fucked up serotonin system due to kratom use. Or perhaps it was because of using/abusing NEP for a while, but I didn't have used NEP in more than a week (low dose, in fact) when used half pill...
I'm gonna try again with the pill but this time full 125, probably around first days of january, that would make almost 2 months since last dose, so surely it wouldn't be too bad in terms of neurotoxicity/cardiotoxicity and all that jazz...
in anycase, I like 3fea more than mdma, I know... I'm the odd one on this, but mdma feels too forced IME, like a chemical is raping my emotional filter, not being myself anymore... 3-fea is more gentle but quite euphoric and improves openness, has that amphetamine undertone of feeling confident without being too "slobbery".
