what is the best supliment for a 16 or 17 year old kid? I go to the gym often or at least i have been but am in a slump because i lack motivation to do it right now. but i belong to balies and i try to get there as much as i can but it is hard because i work a lot. but if there is somehting that would give me the energy that i need to do it it would help a lot. By the way i am 5'10'' tall and 160.
i am looking to put on some muscle so i can look good and hang out with my boys that play football and not be looked at as the "little guy."
