Java Pro?
I know many people who love it -- I tried it and hated it, but the taste of various protein powders is very much a YMMV sort of thing. My favorites for coffee-flavored protein powders are Chike Iced Coffee (best taste -- to me --, has caffeine, but pricey and numbers not quite as good as some others) and Syntrax Nectar Cappuccino -- great numbers, cheaper than Chike, but I would prefer a slightly stronger coffee taste. I end up adding a couple of spoonfuls of instant coffee before blending up either powder though.
I really like java pro.. I drink the rtd caramel. I haven't tried the powder yet, there are mixed reviews out there on it. I'm planning on ordering it.. just waiting to hear back if isopure carries sample packets of the different powered flavors.
