I weight 200lbs, I'm 6'3 plus i have never use protein shakes ever in my life.. so well i started working out.. i started changing well a lil then i stop.. and now i started going back to the gym.. and well im kinda getting better but i still wanna get a better body.. ex.. my pectorals and i always wanted a six pack.. so well i have alot of fat that i will have to burn for that.. anyways.. the thing is that yesterday i bought a protein shake at GNC named- GNC Pro Performance® AMP Amplified Wheybolic Extreme 60™- Vanilla.. is a new protein shake so i went there and the girl who worked there told me that it was a brand new protein and its really good so i bought.. but the thing is that I was reading some stuff about this and it says that after to much proteins shakes you can get kidneys problems and well i have been always a health person well i used to eat burgers etc etc but i stopped that now i eat better like sometimes i eat salads chicken soup etc good stuff i guess.. but my question is .. can i get sick if i drink the protein shake just for a month? i bought a lil bag of it i didnt get the bottle.. so it will affect my kidneys? plus i would like to have some good tips to lose the belly fat that alot of people wish to dont have.. because im one of them.. and how long would it takes me to get stronger and get in shape using this protein shake.. i will really appreciated whoever give me a great answer about my problem.
