MyProtein’s whey used to be the most affordable around, 11 lbs for ~$65. Now for the same money, I can only purchase 5.5 lbs. Are there any cheaper alternatives?
The cheaper you go the more fillers the protein will have, mostly in the form of carbs. It’ll be up to you if you want to sacrifice quality for cost. Nowadays I don’t see 11lb bags being under $130-150, and 5lb bags being in the $60 range ($50 on sale if you catch them).
