GNC Pro Performance Weight Gainer 2200 Gold. i was wondering if this is a good idea because a friend told me it didn't work on underweight guys so i would like to know if my money will be worth it, and also 2200 calories sounds like a lot for one serving, and if it works how much weight will i gain in a 96 0z bottle. Thanks.
