I've been using whey isolate peri-workout but I've been curious about trying BCAA instead, so I've been looking at the two brands mentioned. Xtend has artificial colors added, while Modern doesn't. Based on that, I will go with modern if I experiment with BCAA.
I've had it with all the products that are artificially colored. Yeah, I'm sure a little artificial food coloring doesn't hurt anything, but when you're taking 3 or 4 products a day with artificial colors, you've moved beyond just 'a little'. It's nice when your protein drink tastes good, but who gives a damn what color it is? Buy an opaque shaker cup if you can't handle the thought of drinking a product that isn't brightly colored. I wish manufacturers would stop using artificial food colorings when there are good alternatives (beet extract, for example). If my protein drink is fluorescent green, it doesn't help my training at all. I'm drinking it for the nutrition, not because it looks like Kool Aid. Remember when weight training was a healthy activity? Now it's about selling garbage products to teenagers.
