My first post!
As a 39 year old that just sent his kid off to University of Texas on an athletic scholarship, I feel like I need to put in my opinion on this one, since you are at a similar age, and I've been through the whole "try anything and get taken by the people at GNC" type of thing with my kid...
You are at an age where you have many things going for you when it comes to building lean mass, strength, and endurance. While you need to also be careful not to overtrain, you also are producing hormones at a high level, and, as a wrestler, I would assume you are in pretty decent condition at this point. As stated by warlock, stay away from all the crud that says it will give you magical results. The Xcience products are indeed overpriced, and lots of different packaging and glitz for silly stuff. Your best bet is to be sure to eat often (about 6 times a day) of very high quality foods, take a multi vitamin (I actually would go much further on the vitamins, but you are not my kid, so I'm not going any deeper than that) and get yourself some of the Whey Concentrate at Wal-mart or target, etc. This is not the "best" form of Whey, but it's still Whey, and it's all very good to a degree. Take a scoop worth before a workout, then another scoop when you get home from the workout. Possibly start the morning off with a scoop as well, if you do practices in the morning.
Next trip to the grocery store, get about 6 tubs of cottage cheese and incorporate this into your last evening meal, for some slowly digested protein for the overnight.
Also, I'm a HUGE fan of flaxseed, flaxseed oil, and fish oil. If you make these a major portion of your total fat intake, you may well see some improvements in your condition that exceed anything the magic potions will do.
Lift smart and lift hard. Remember that strength and size don't come from one rep maximums...there are all kinds of workout plans that you should research to help you increase performance for wrestling, or whatever you are striving for.
Though I was going to avoid this, you COULD consider a responsible dosage of creatine, or something like a creatine/glutamine/taurine powder blend. I use this, and in my research it appears that this really is a worthwile supplement...this is from what I consider some very conservative experts on such topics.
As a young athlete, you will probably find that small changes in your workout plans and nutrition will give you big gains in performance. I know from working with my kid that when you are a finely tuned machine already, incremental changes can show big results. Kind of like high octane gas in a new sports car vs. fuel changes in an old work truck...I myself am kind of like an old international scout with rusted through frame...it takes a lot of work to keep me running.
Good luck with your wrestling career!
