how do we know for sure the claimed amount of protein in one service is accurate?How do I know it's, lets say, 30grams of protein? it could be 8 grams of protein and 22 grams of shit.There was a document about the amount of carbohydrates in bred... the package claimed 20 grams of carbs, but guess what? They went to a lab and put the claim to a test, and voila, the reality was it had 30 grams MORE than what they claimed.
There's a very simple solution to that - just buy a protein powder that's 100% whey - it'll either be isolate, concentrate, or a blend of both. Me personally I use 100% whey concentrate - for every 100g of powder there's 82g of digestible protein in there - isolate is even better - around 95% - the only reason I don't buy that as I haven't noticed a major difference between the two and isolate is way more expensive.
