I used almost half of it then my girl says- hey this is expired in June. I was like damn, those bastards at Max Muscle!! It tastes weird and smells weird too. I hope it wont make me sick or something.
that stuff smells funky anyway, so don't worry about that. should be ok. but you can get a new can for free since they fucked up, so i say tell them you hurled from it and they better fedex you one ASAP.
