with respect to Vyvanse you'll see that the dosages tend to be much higher in part that's because vivance has if you recall it's that lysine which is a big molecule stuck on D amphetamine which is a smaller molecule and so the dosages of Vyvanse tend to be in the hundreds of milligram ranges but most of that 100 milligrams of Vyvanse is not going to be the damphetamine it's going to be the lysine which doesn't do anything in the context of treating the brain it's just there to control the slow release so it's thought that 100 milligrams of Vyvanse translates to roughly nine milligrams of Adderall
