Protean is awesome. The flavours are really unique and tasty (brown maple sugar? c'mon!), however the macros are not great for a protein supplement.
I would have rated it higher if not for the macros. While most people could quite easily fit this into their diet, I prefer a shake to have undeniably better macros than a whole food, otherwise 9 times out of 10 I'd simply buy the food. However for what it is, I really enjoy protean. Had a big serving today, beat flavoured milk hands down. Mix it with water, with milk, with cream, with whatever, each flavour is delicious.
