Methylone Dosage
by Erowid

Methylone (bk-MDMA, Explosion, Ease, m1) dosages are not well documented in the literature and the following dosages are based on a submission by Winta and reports gathered by Erowid. Methylone is generally available as pure crystals and rarely, if ever, pressed into tablets. As one contributor notes, "The most reasonable dosage recommendation for such a poorly documented substance would be 'none at all', but since this advice is unlikely to be taken seriously." The variability in response reported is reason for special concern and should be taken seriously by those considering ingesting methylone.

Dosages vary considerably between individuals, with some methylone users reporting that they "never" exceed 100 mg, while others report "barely reaching" threshold at 200 mg.

Oral Methylone Dosages
Threshold60 - 120 mg
Light100 - 150 mg
Common100 - 250 mg
Strong160 - 270 mg
Heavy250 + mg

Onset : 15 - 60 minutes
Duration : 2 - 3.5 hours
Normal After Effects : 6 - 24 hours

Some respondents say that increasing dose with methylone beyond 100-180 mg causes increased physical effects and does not substantially improve the empathic cognitive effects.

Insufflated dosages appear to be slightly lower than oral dosages.

Stimulation / Sedation
Some have reported worrying heart rate and blood pressure increases at doses over 180-200 mg. While some people report stimulation, there are also reports of seemingly paradoxical sedation effects.

We have one report of a male who found it took over 250 mg of material to approach the bottom of a 'common' dose and found 300 mg to be "just right" and the same material affected others at more common doses.

Boosting / Bumping
Methylone is sometimes used with a larger "attack" dose (first dose) and then smaller "bumps" to maintain the effects for a longer period. These bumps are taken orally or insufflated and are often around 30 - 100 mg oral and 20-80 mg insufflated.

A third-to-half-dose re-dose usually extends the duration for another hour, a full-dose redose often extends the duration for another 1-2 hours. Some say that taking a booster dose more than 2 hours after the initial dose will not result in extending the desired effects.

Every individual reacts differently to every chemical.
