Even with pure MDMA a lot of the time 100mg - while an amazing time - isn’t really the “fun dose”. Ideal for me is 250 across a night (maybe 125 then 75 then 50) if it’s like a full on music festival. In a mellower context (camping or a house roll or something) I’d recommend one 100mg dose and no more though
Its 5 times the fun dose. Try doing that with some other drugs and it can be life threatening..
