​It is possible to buy oxycodone online, but it may not be so easy to get real oxycodone online. Legitimate pharmacies will fill an oxycodone prescription as long as you can prove you have a prescription, but there are also illegal pharmacies that may ask for a prescription but will do little to check its legitimacy and will send fake versions of the drug. Scam pharmacies will send pills that contain little or no oxycodone that look exactly like real oxycodone, with all the same stamp marks found on real pills. The problem is that the illegitimate sites look exactly like the legitimate ones. It can be difficult to know which site will send you a bunk product.
