Consumer advice
If you're already hitting your daily protein targets through food (~0.7–1g per pound of bodyweight), you don't need this. If you're falling short — common for people training hard — a WPI shake is a convenient, effective fix. Kaged is a solid choice: they're transparent about ingredients and test for banned substances, which matters if you compete. That said, MyProtein or Bulk's own-brand WPI will get you the same protein at roughly half the price. Buy Kaged if the third-party testing and brand trust matter to you; go generic if you just want cheap, clean protein.
