theyre both oxycodone as said above. however a very experienced user such as myself can notice a very very slight different between the same dose of the too, especially when snorted, because of the APAP/tylenol
^^ yea no matter what, oxy always feels a little stronger and always hits faster. its just overall a much better high. especially snorting, that shit hits me like a truck in under 5 minutes, whereas with perc i end up with a rediculously clogged nose and a weak high that never seems to really peak. although with perc the nodding stage seems to be a little longer for some reason
