What is a good protein powder for a 15 year old?

SPOT ON!!^Egg whites are one of the best sources of protein if NOT the best. SKinLeSs chicken breasts are also very cheap and can be bought in pre portioned sizes of 6oz or 8oz which correlate to 22g or 30g or protein roughly.

Depends do you want a weight gainer shake? A low fat shake? and also is this an after workout shake or just a protein supplement (in reality that's all protein shakes are an expensive form of protein, the exact same protein in milk/meat and nuts) ??

Weight gainer

- I loved Muscle Juice 2544 when i played football. great taste, will get you big not just muscle wise but will also pack on some fat

DO NOT BUY FROM GNC!!!! They're a rip off!! I am dead serious compare their prices to online sites and it's not even close. Factor in shipping/handling and they still suck!! Use googles shopping item to compare prices. Considering i only wait 3 days TOPS to get my protein in the mail it's well worth the wait financially.

100% whey protein or you can save money and eat egg whites after your work out with chicken breast with no breading you'd save money man my uncle is a body builder your 15 man try whey when you are older but suggesting 100% whey cookies and cream good taste.

whey protein

get a protein powder that is low on carbs.. low on sugars and calories

try ISOPURE or ISOFLEX
