Most people with geniune medical need for oxycontin can't even get them from a walk-in doctor after all the negative press. Online - forget it!
If you've been prescribed oxy before, a pain clinic MIGHT presribe them if you can prove it, and that your pain warrants it...but it's still rare to get them even seeing a doctor in person.
Hydro is the best you'll be able to find online. Seems that oxy is only available 'on the street' - and I've always wondered how drug dealers get them to sell, when those who truly NEED them get turned down.
Sorry, buddy, but you won't find any oxy from any online doc.
