Pure chemical free whey protein minus the fillers and additives is the WHEY to go. Consume ample amounts of whole food proteins and drink plenty of water. There is no ';super supplement'; out there!With whom i take advise before taking whey protein or any other supplements?
ive taken many supplements over the past 3 years personally the only supplements that work are protein and creatine anything else you get from gnc is a joke thats how i feel.... talk to one of your trainers or people in the gym.
go to a certified nutritionist AND a doctor
