What’s the difference between WPI and WPC?
“..While WPC is micro-filtered once, WPI is filtered a second time removing more of the fats, carbs and sugars, meaning it is a purer and more refined whey protein than WPC..”
Protein blends are a mix of above and possibly other ingredients/fillers hence possibly cheaper.
