First off let me start by saying I know dif pills use dif fillers but what im talking about has nothing to do with the fillers used in IR vs XR, JUST the amphetamine properties. I was crushing up an Xr the other day and my buddy says he refuses to use XR even if crushed up because it is not the same as IR when it comes to effectiveness in his opinion. Im under the impression that if you crush a 20mg xr and crush a 20mg ir, your going to have essentially the same thing, am I rite?
