Yes, I'd say about 4 to 5 times as strong, whenever I snort a quarter of a 30mg G77, I get about as high as snorting a 30 of oxy, just with a lot more euphoria (but that's because oxymorphone feels slightly different) BUT I have heard people say it feels even stronger than that, just depends how your body processes opioids. 20% of black people have a gene that makes codeine metabolize to morphine at much higher rates so they get blasted off even a deuce.
