What is your question? Which is stronger? If so, this has been covered a shot load of times. Anyways, the bioavailabily of IV is close to 100% but there isn't really that great of a rush with IV administration. Orally, the BA is also very high. Although I do like shooting things, when it comes to Oxycodone, I would rather just take them orally. There isn't much rush, and since the oral BA is so high anyways, shooting it won't make it much stronger and will greatly reduce the length of effects. Stick to oral.
