You can make the scoop as big as a measuring cup and call it a 200g per serving protein. You need to compare the grams of the serving size (weight) to grams of protein...and how many servings in the container.
For example, I stupidly bought Vitacost ARO Black Series Protein because of price. 20g of protein in a 45g scoop, 50 servings in a 5lb container. ON GS is 24g of protein in a 30.4g scoop, 74 servings per container. I don't have to break down the math, but the ON is a much better value and the ARO would have to be WAY WAY cheaper to justify the protein difference. And even then, you're ingesting a ton of filler that you might not want.
So for the Walmart protein, compare how many grams of protein are in each scoop (gram weight) and see how many scoops are in the container. Then do the math and see if it's a good value.
Not true.... That's a complete misdirection of advertising in the industry.
That takes away from the important things....
The source of protein, method of processing, carb sources, fat sources, additives...etc
Personally I'd never buy ON...
Milk Protein Isolate is superior. (A blend is best -- don't do straight whey or casein)
ON doesn't state the % concentrate they use. (Concentrate is available from 40-80%)
Uses Ion Exchange --- (growth peptides are lost in this process)
Added nonessential aminos
IMO The best 2 proteins:
USPlabs --- OxyElite Protein
PES --- Select Protein
(Someone else mentioned Beverly UMP which I would put in my top 5)
