I don't see the negativity on the Soya Protien Isolate. I know certain people think it has to be pure Whey but there has been studies to show there is not much difference and for me it works. http://www.bodybuilding.com/fun/drobson71.htm ...... says it better than I can
You get what you pay for... Make it work with your macros and it doesn't make much of a difference as long as you are meeting your own criteria consistently.
I got the Black Friday bundle 2 years ago with 5KG protein, BCAA's and Creatine for £17.99 - amazing deal, but got so sick of 1 flavour! Now I pay more for the privilege of switching up flavours and saving space. It's still a pretty good deal 5kg for £37
