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.
