Haha. If I'm honest (I hope people I talk to on here regularly aren't too shocked) MY name is not actually Chemically Enhanced
Regularly Oxycodone you get it all in your system in one go immediately (well, ya know, more like 45mins if you've just eaten) and lasts around 5 hours before you need to re-dose. OxyContin tablets release slowly into your system over a period of 12 hours. The dose if how you tell. If your pills are 5/10/20/30mg they're *probably* instant release, while the slow-release ones come in 20/40/60/80mg doses
