Uhhh..... i dont think 10 times stronger is right. From experience of many opiates it is about 2-3 times stronger. Example.... If you have a Opana 10 its more like an Oxy 20-30... 10 times is an over estimate.
i would even cut the pill into quarters and sniff 1/4 wait 15-20min and see how you feel, that way you can keep your tolerance down if it happens to be enough for your buzz
