How many mg is a green Percocet?

Anywhere from 2.5mg , 5mg, 7.5mg and 10mg. Of course the nature of percocet means it also contains acetaminophen (Tylenol) along with the oxycodone...thus the medication called percocet (Just an oxycodone and Tylenol combination) The only thing that varies is the amount of Tylenol in each pill.
