MDMA (Molly, Ecstasy) Dosage

The second safest option is to use MDMA responsibly, and the most dangerous option is to use MDMA irresponsibly.

Most important things to know about MDMA dosage

1. Guideline: your weight in kg, plus 50 = total dosage in milligrams for the session. (1.5 mg/kg with a 120 mg max may be more optimal, but the weight + 50 is a good rule of thumb). If you’re more cautious or want something a little less intense, perhaps weight in kg + 35-40.
2. If finger dipping powder: ideally switch to weighed doses, but if not that, use “crush, dab, wait.”
3. If using tablets and you haven’t taken a tablet from this exact batch before, start with half, or less.
4. Low doses may be particularly important for your first few uses, as you might unknowingly have a health condition like malignant hyperthermia that makes MDMA more dangerous. I believe your weight in kilograms + 20 is an appropriate and cautious first dosage.
5. A study found that MDMA desirable effects are maximized, and undesirable effects minimized, at doses between 81-100 mg.¹
6. If you’re unwilling to use these dosage guidelines, please make extra sure your friends are aware of the signs of heat stroke and heat exhaustion, and pay extra attention to keeping cool.
7. “I think there’s no “safe” dose if you have a preexisting health condition contraindicated with MDMA.” For example, malignant hyperthermia, which you may have but be unaware of.
8. A small female died soon after consuming 500 mg of 91% pure MDMA. It is highly probable that they had a health condition that interacted dangerously with MDMA, but this shows why it’s important to pay attention to dosage.
