You always have the option to just eat healthy if you want. I stopped throwing money out the window a long time ago. I eat 1-1.5g per body pound everyday no problem.
There only reason I would use it is if I didnt have time to eat. Its a supplement, but the industry wants you to think its a necessity to build muscle. The main thing you wanna watch is the cholesterol, some are loaded. Just remember that Whey is just another refined product, I avoid it.
