Beneprotein
I think most of the places like popeye's sell unflavoured protein but I have never found them truly unflavoured. I used unjury unflavoured at first , now that I can eat more I just have click generally. Sometimes I mix protein in with puddings, or in my favorite protein peanut butter balls.mmmm
My favorite proteins so far are click, mint cookie from matrix, chike makes some nice ones as well that mix well and taste good. I liked the nectars at first as well. I hated the thickness of the shakes at first and drinking a crystal light type beverage at first was easier to get down. I also used to use the RTD chocolate drink from costco - was ok and easy but not the best.
I found a product at Sunrise. It's called Xtreme Power Whey Isolate. Natural flavour. There is 32g of protein per scoop. I haven't used it yet but I tried a bit and didn't taste anything. I had to ask for it because it wasn't easy to see on the shelf with all the flavoured items. I just happened to be in the mall. Next time I'll stop in at Popeyes. I hear their prices are good.
Cheers!
