When I was 15 I remember sitting in class and suddenly I'd pitch a tent out of nowhere... lol. Kid, do you know what more
nitric oxide in your system is gonna do to ya?
Man, almost makes we want to say go for it just for laughs but naw. Don't take Nitrix, NO2, NO3 or whatever the hell kinda L-arginine supp they come out with next. You've got plenty of nitric oxide in your system as a teen. You don't need the energy boost. Stay off the weed though. It'll kill your energy, besides turning you into a moron.
At 15 you're better off with some
whey protein before and after your workouts - if you want to get big. Otherwise, eat well. At 15 you're goin out to McDonalds 3 times a week and eating french fries every lunch, eating candy bars, drinking 3 cokes a day. Have you noticed how many fat kids we got in this country? If you don't watch what you eat, you'll be dead at 50 so fat they'll have to bury you in the shell of a grand piano.
Lol. Save your money and spend it on a nice girl. Take her to the movies. You'll need it. I heard they're jacking ticket prices up to $20 a person soon. :P
