I'm not certain on this but based on what I read on it's site, I'm assuming it uses the OROS delivery similar to Concerta and Invega.

Nope. Doesn't use OROS. The inactive medication is released from the capsule as it passes from the stomach into the small intestine. It's in the small intestine is where all the action happens and thus converts it to d-amphetamine at a controlled rate.

This might help more.

Wow. I checked the site before asking this question and the video wasn't even up yet. What a change in a small time frame.

Thanks for sharing the video.
