I know for a fact Cena juices, he told my friend ( a competitive bodybuilder) what they're all on, don't really care if anyone believes me or not, I've posted this like 10 times now. According to Cena most of the guys get Deca, Cyp and GH prescribed by a doctor, and that's what they run all year. I don't think Cena would have any reason to lie seeing as he was doing a 2" line of blow at the time he was telling my buddy this. Oh and yes, Cena is a BIG Mofo. Adonis get off the crack pipe.
