Vyvanse maintains a long, steady, consistent blood level all day — advantages over Adderal. But
Vyvanse takes three hours to kick
in, while it is metabolized
in the liver so it has that nice long steady life. On the other hand, Adderol kicks in immediately, and has a short effective life. Perfect fit.
Adderol is like Special Forces who goes in to accomplish a specialized mission, and then leaves.. On the other hand, Vyvanse is the army, does all the heavy lifting and 95% of everything else.
