What do 31-inch biceps look like? Glad you asked! Bodybuilder Moustafa Ismail was recently awarded the Guinness World Record for the biggest biceps in the world. Born in Egypt and residing in Massachusetts, Ismail told the Guardian he eats 6.6 POUNDS of protein a day on top of six meals. How much synthol he injected on a daily basis is still up for debate, since obviously he didn't disclose that little detail. Have fun with the side effects! But seriously, look at that flex! If Ismail moonlights as a bouncer, it's going to take a really stupidly drunk fool to try to start sh*t with this guy.
