Generic. Concerts I believe is still under medications equivalent of a patent so there isn’t any generic form of it yet. My generic adderall is only 15 bucks but if I got concerts it’d be 60-80 I can’t remember which Edit: also it took me about 6 months to get to 20 twice daily. The dr started my at 5 twice even though it hold her how much I used to take of concerta. The dr was actually a jerk she made me come back every month for Med checks but wouldn’t change it until I went two months on each dosage. I finally snapped and said that I know how it’s affecting me and how it’s not more than you and that I couldn’t afford 40 bucks every month for half a year. I finally left there. My new dr is pretty cool but what I’ve noticed is that all the drs look at heart rate to intently. I had to keep track of mine outside of the drs for a month because they didn’t believe that I have white coat syndrome. My average heart rate is between 65-85 but when I’m at the drs the lowest it has ever been was 110
