How we compare whey protein
Most websites rank whey protein by price per bag. But a 2.5kg bag for €30 isn't necessarily cheaper than a 1kg bag for €15. It depends on how much protein is actually in it.
That's why we calculate the price per gram of protein. This is the only fair way to compare whey proteins, regardless of packaging size or brand.
Formula: Price ÷ (Servings × Grams protein per serving) = Price per gram protein
