I take protein shakes, but it gets old after awhile blending shakes. Are there any protein drinks on the market that are already mixed where someone doesn't have to mix the powder?
Well, actually, there is. In our gym the boss stocks the fridge with drinks, and he buys 2 kinds: a general post-workout recovery drink, which has 50g of protein and 75g of carbs, and then a drink which is mostly protein, but does have some carbs in as well.
You should find such drinks on the internet...BUT, why bother? I never asked the gym boss or anyone else, but I doubt pre-made protein shakes are very cheap. It's probably more economical to just buy whey and mix up your own.
You don't need a blender, btw. As TyTe`EyEs said, get a shaker bottle. I have a Met-Rx shaker bottle which you put your protein and liquid into, put the lid on, then shake it up a bit. It works absolutely fine. It's one of these:
