You might get a bit nauseous and possibly throw up since you are a new user, but you definitely will not OD. I'd advise you not to take Percocet often recreationally though, as the acetaminophen is bad for the liver.
Hi! Welcome to Bluelight! I'm new myself. If you can tolerate the nausea associated with taking opiates, you'll be fine. Personally, I enjoy oxycodone itself and it's relatives. But I can't even take 5mg by itself anymore without throwing up whatever I had to eat earlier that day. Anyways - enjoy. 25mg isn't an OD.
HEY I took exactly what you just wrote and i felt nothing
i had an empty stomach when i took them and everything
and at the time, i was opiate-naive
they were real percs too straight out of my script from my wisdom teeth removal
