Being intimately involved with the fitness industry, I know quite a lot about protein supplementation.
Taste is a big thing. Unfortunately, a lot of the powders that the companies actually took the time to make it taste good also have a ton of other things besides just protein>.< Creatine, taurine, gensing, and the list goes on. Some of these formulas even have small bits of viagra in them.
A lot of guys get really picky about what they put in their body, crappy taste or not. They come up with things like: PROTEIN PANCAKES, simply mix into the pancake batter and have at it. PROTEIN BIQUITS, yup, make a batch once a week and put tons of butter on it. MILKSHAKES. PUDDING. MUFFINS. Anything that's baked or make up, you can load it up.
Don't forget those energy/protein bars.
And just a bit of advice, go for short ingredient lists. "100% Whey Protein" is a good name. Don't get the whey from walmart, it will load you up with so much sugar and caffiene and whatever else is in it you'll get high, and then you'll vomit. Whatever doesn't come out will make a loud exit during your next BM. I've heard good stuff about milk proteins. People on here get pissy when I say soy protein, but that stuff tastes the best out of all of them. Anyone tried peanut butter protein powders?
