personally, i think training 6 days a week for a 16 year old is way too much. here's my suggestion: stop reading those supplement ads while you're taking a dump. get yourself a good book on bodybuilding like:
arnolds new encyclopedia of modern bodybuilding (no bodybuilder should be without this)
bodybuilding 101 (good for the basic info)
extreme muscle enhancement (i'm currently reading this)
and do some research on the topics of OVERTRAINING, NUTRITION, RECUPERATION
speaking as a former teenager who thought things would happen for me overnight...slow down, more isnt better! i look back on what i used to do and i was completely wrong in those days. i used to think that just cuz i knew an exercise, i should do it and i should be doing 4 sets of it. i was at the point where i was doing around 20 or so sets per bodypart at the age of 16. i was training almost every day and nothing was happening...sure i got a little bit stronger but not nearly as much as i could have. if i could go back, i would do 2 things differently...first one being EAT MORE and second, train a bit less.
stop following the workout routines that you see in FLEX magazine, those routines arent for you...at least not at this point in your life. you need to focus on your foundation lifts like squats, benches, deads, bent rows, shrugs, pull ups, curls, preachers, military press and skull crushers. i'm willing to put money on the fact that you're doing stuff like cables, pec deck, tricep kickbacks and other isolation movements.
if you feel like you need to supplement, thats fine but make sure you got your food intake taken care of first...as EVERYONE has stated above. that should tell you how important it is. i'd suggest protein first then glutamine. nobody ever got huge off taking a NO2 type product.
my last bit of advice...take some of the money you planned on spending on supplements and hire a trainer. not your typical 24 hour fitness employee but a real trainer or certified strength coach. you will learn a lot in just a couple of sessions.
