Extreme Blendz

The gym I work at serves protein shakes and smoothies from a company called “Extreme Blendz.” We make all the shakes with their proteins, plus whatever ingredients the recipe calls for. They’re awesome, to be honest. Anyway, I was wondering if anyone had any info concerning the quality and such of the protein; I’ve been doing research, but the only info I can get is put out by the company, so I don’t want to take it as truth without some confirmation. I’m just trying to find out if this stuff is worth putting into my body; I mean, I get the shakes for free, so not only does that save me some money on a meal, it also alows me to stretch my Grow! a bit further…any input would be awesome
