From what I’ve heard from doctors, xr is equivalent two doses released into your body, its not a steady state release as you might expect. Its basically one ir and another ir wrapped in a package that takes a few hours for your body to digest. So if you don’t really have issues with timing and xr costs you more money then ir is totally equivalent and ok to use.
If it feels different, then it might be manufacturing differences. To really determine the difference you would need to get it from the same manufacturer for both the xr and ir versions. Which doesn’t surprise me after listening to a podcast about a book called bottle of lies.

this is how i’ve understood it to work, yeah. the “feeling” of the ir is much different than the xr (for me, that is). i’ve tried comparing the teva generics of each formulation, and the xr just didn’t last as long as two perfectly-spaced ir doses — about five hours for one xr dose, eight hours for two equivalent ir doses. i have a feeling that it’s a combination of manufacturing (as you mentioned) and body chemistry to a lesser extent. vvyanse seemed to work the best, but the 70mg capsules felt slightly too weak, and a month’s prescription for them is literally 9x the cost of the adderall.
