As far as I know all oxycodone IR 15mg and 30mg pills can be fairly easily injected.. Oxycodone is obviously water soluble, and there are no tricky time release mechanisms in any of the instant release pills. The only difference between the generic brand Roxis are the inactive ingredients, binders, fillers, dyes, etc..
If you look up the ingredient lists of each brand of generic oxycodone you can find what each contains. You can also find the solubilities of each ingredient. That being said, injecting ANY pills without using a micron filter is completely against the scope of harm reduction that bluelight is about.
If you are a regular user of IV oxycodone pills I highly recommend reading the micron filtering mega thread and purchasing some. The miniscule financial investment will save your veins and body multitudes of harm.
Also, since this thread is completely not suited for Other Drugs, I am going to close it. If you use the search function you can find various discussions that contains people's opinions regarding the most favorable IR oxycodone pill brand, to inject..
Please read the rules, as you have beena member here for quite some time now and manage to continually find ways to break them.
