you can find syntrax nectars at gnc and vitamin shoppe but I get my protein from mybariatricpantry.com it's cheaper and you can also get sample packets to try them out first before buying the big tub so far the syntrax flavors that I like to mix with milk are the cappuccino, fuzzy navel, strawberry mousse and double stuffed cookie and the ones I mix with water or juice are the syntrax ice tea (I mix that with diet peach Snapple or crystal light ice tea flavor) and the lemonade... if you want some links I'll be happy to send you some... also that website has some other coffee drinks from different brands that I haven't tried yet, that you can drink hot or cold and they have caffeine.. I just got a sample one so my husband can try it so well see how that goes
