Maybe old news...I don't know...but I found this site yesterday http://www.truenutrition.com/
where you can custom mix your own protein powders and supps. They have a great selection of powders to mix and match including hydrolized whey, beef protein, iso, concentrate, casein etc...then you can add carbs of varying types and a few other options like flavors. Price is very reasonable. So basically you can make a shake for PWO recovery with hydrolyzed whey, and make another batch with say iso and casein for those that like the slower absorbed proteins.
You can also create your own xtend- I made some yesterday by adding BCAA's, some CM, and electrolytes- turned out cheaper.
Anyways, just wanted to throw that out there and was wondering if anyone has much experience with the quality of their products before- customer service seems good, I ordered last night and it's shipped already.
