You probably know me by a few names — mandy, E, MDMA, or just that pill a friend handed you at a party.

I have been studied more than you might think. I can be gentle, and I can be genuinely harmful — and almost always the difference comes down to how well you know me before we meet.

So let's sit down. I want to tell you about myself.

how much.

a dose, measured in care

The personal dose calculator needs JavaScript to do its math on your device — your weight never leaves your browser. Without JS, here are the universal numbers:

starting dose

1.0 – 1.5 mg/kg

of your bodyweight (e.g. 70 kg → 70–105 mg)

hard ceiling

120 mg

maximum initial dose, no matter your size

If you're thinking about a second one

there's a window. outside of it, things get ugly fast.

0:00 1:30 2:30 4:00+

wait, please

if you must, now

too late — don't

The window

1.5 to 2.5 hours after your first dose — no earlier, no later.

Half, not more

Half your first dose, maximum. Never a full second dose.

After 2.5 hours

Dopamine keeps climbing while serotonin runs out — that's the exact chemistry neurotoxicity is made of.

why timing matters

CYP2D6 enzyme inhibition by MDMA causes non-linear metabolism. Redosing too late increases neurotoxicity without restoring effects.
