I absolutely LOVE Radix! I have never been able to commit to a 1-2kg bag of "exotic" protein powder (i.e, anything that isn't chocolate or vanilla" and Radix provided the best solution. I tried the free 5 sample pack of the whey isolate. This has to be one of the best WPI I have ever tried - I had it as a shake, in protein oats, and made egg white protein pancakes with them. I was hooked (to say the least). Not grainy at all, no chemical-ly taste, and mango had to be my favourite flavour (usually go for choc or vanilla). I got the 15 for $15 too, and am loving it. The only caveat is that I think the coconut and blueberry flavours smell more like the flavour than they actually taste like them. I am coeliac and dairy intolerant. Both the whey and plant proteins from Radix have not upset my stomach. Legit recommended this protein powder to everyone I know. Price point is great, and overall just a great protein powder.
