Is there a cheap simple whey only powder that I can later add my bcaa to per serving that I can buy in bulk? I'm low on cash and need to bargain hunt and tired of blowing wads at vitamin shoppe every month. Quality is important but I just want to mix my own extras instead of trusting in the proprietary blend crap. Is this a silly idea? I just like the idea of concocting what I put in my body rather then trust some manufacture is delivering the optimal blend off bcaa, nutrients and minerals. Hope it's clear what I'm getting at with this enough for some good leads. I've never been an online supp shopper.
