DUDE! Don't do the chest, there is too much stuff (nerves and veins and shit) in there. I've heard of guys doing their bi's, but I don't see the point in trying and possibly fucking up, and again I think the potential for messing up is too high. The glutes are the way to go bro. Are your glutes getting pissed off from all the hits? I know that mine did from the Enanthate. You could try the quads, but I bet you will be limping for a day or two.
How many more weeks are you planning to be on? (I lost count on mine, but still have gear left..)
