methylone for me is always tinged with a tense paranoia on the comedown, like taking way too much amphetamine. dont have this problem with mdma, its because methylone is a more powerfull releaser of dopamine than mdma, and it releases wayyy less serotonin, giving it a more methamphetamine style profile in high doses.
methylone nearly always leads to compulsive redosing and going insane, shitty drug with a nasty dysphoric afterstim vibe of horror like strong speed
