Blenders are one of the best kitchen tools ever made! Not only good for protein/fruit shakes and stuff but also a good way to down a bunch of veggies at one time or add more nutrients to a soup by blending greens and then adding that back to the stock(if the blender itself can do so of course).
Here is a drink I like to make...
Red rooibos tea (chilled of course) as a base, a few tablespoons of hemp seeds(not the isolated protein, just the seeds themselves), a teaspoon or less of a batch of freshly ground flax seeds (otherwise they taste nasty for me), raw local-ish honey, and a good whey powder(I like Biotest's 'natural' flavor one, but I'm sure there are others processed just as well). Also, if I have any I add tocotrienols.... either from rice bran(white and malty) or palm fruit(tan and nutty), or both. I'm currently out though. If I really want it to be "secret power xxx" or whatever I'll take caps of really good mushroom supplements and open then and throw the powder in. I'm talking about adaptogens here, not the kind that make you see Buddha or anything.
Sometimes I blend everything first and add my whey in after on the top of my glass and stir it in a teaspoon at a time.... I have found it to taste better, with the particular whey I have been using. It's a pretty nice drink.
ah I forgot.. sometimes I add banana to the recipe above...
