I have both man. Combat Powder Cookies n Creme and Smores! Also have Dymatize Cinnamon Bun. Like the guy above me said, they are completely different proteins. If you are looking for something to take post workout, get the combat powder. If you are looking for something that tastes good and to drink before bed as a snack or during periods of the day where you can't get food, get Dymatize. If you can afford both, get both
I take CP post workout and sometimes drink it with my breakfast. I have been taking Dymatize right before bed every night as a snack because it tastes so good!
I currently take BioX Whey Complex (Chocolate peanut swurl) for post workout but i was thinknig of using one of these to for breakfast/night time shakes. Dymatie seems to be the obvious pick for the casein protein but the Combat powder seems like a great mix and does contain some casein protein within the mix.
