By far the best ADHD treatment out of the 50 or so other stims I've tried, and of course better than any of the non-stimulant and nootropic options I've tried.
It retains all the positive aspects of d-@mp and actually has a slightly more clear mental stimulation that makes it perfect for studying/reading and actually getting things done, lasts the entire day rather than 6 hours, much less vasoconstriction and general physical discomfort/anxiety, no disruption of appetite or sleep, just overall feels a bit like magic.
I really wish more doctors would prescribe it but the stigma causes issues for both parties. Not only do doctors have an unconscious bias against it, but I feel some are afraid to prescribe it because their patients will likely reject it/have some sort of negative reaction. I also wonder how big of a role placebo plays in this, if all you've seen about m3th@mphetamine your whole life is DARE propaganda and people living on the street that has to play a role in the experience. Regardless it seems the small percentage of people who manage to get it prescribed rate it very highly, you can see on drugs.com it was rated #1 for ADHD with a 9.1 and 8.7, while d-amp is rated 8.6
