if you go I.M. then yes, and thats when most guys split it up, but for me, i just go subq in mid section once daily. I still get great pumps, and im a firm believer in that subq applications are better for fatloss, and I.M. applications are better for localized muscle growth.
Im plenty big enough for my liking lol, and for most other peoples liking probably for that matter lol, so i just keep it simple and go subq, and i feel the benifits just as well over all, but if i was just starting out, i would and i have done I.M many many times for months on end, and yes felt like that particualr muscle was benefitting more
