D-MAX, or DMAX, is Dimethylallylxanthine. Sometimes 10 times stronger than Caffeine (TMX, Trimethylxanthine), yet the same amount of heart stimulation. So 20mg DMAX
will feel
like 200mg of Caffeine in mental effects, yet be super mild on the heart and blood pressure
like 20mg Caffeine. While caffeine kicks in in 1/2 an hour, DMAX kicks in at 3 hours.
