I liked the "Low-Carb Men" formula from proteinfactory.
It is 1/2 CFM Whey and 1/2 Ion-Exchange Whey, with some CLA fat. Maybe a couple of carbs. $9.91/lb and comes in 5 flavors --
Vanilla, Chocolate, Banana, Fruit Punch, Orange.
I get it sweetened with Splenda and it tastes pretty good. Mixes easily with a spoon too.
They offer regular Whey (WPC) for just $4.25 too. The better protein though doesn't give me any bloat.
I got to tell you that they have been slow processing orders lately, so it could take over a week to get your stuff. Otherwise, no complaints.
