yes bro , you are right. You will not find a single protein that will say "hey people my aminoacids concentration per protein serving is too low to buy it , so don't buy it".
1)Active Ingredients: The most protein supps have a very low concentration of aminos.
2)The 80% or 90% protein doesn't mean anything to me , if the included aminos and vitamins exist in a very low concentration per protein serving or do not exist at all.
3) I can't prove that most proteins are flours , but my biochemist can. He tested many supps in his lab. As soon as I have in my hands some test labs , I will upload them.
thanks for your help lads.
1)How do you figure? 20g of protein has 20,000mg of amino acids irregardless of brand OR source. the ratios of each amino acid and the types of amino acids vary but each given species of protein(ie,whey vs whey, soy iso vs soy iso,chicken vs chicken ETC) has the same amino profile. the difference comes in their moisture,fat and carbohydrate content(and certain aforementioned "active" subfractions in milk derived powders or isoflavones in soy derived powders).
2) This is redundant of my first response but 20g of actual whey protein from one brand is going to give the same results as 20g of whey protein from another source, provided the processing method is the same(and even thats splitting hairs)
3) there ARE indeed shady supplement companies that add carbohydrate fillers to their powders to reduce cost but it would be economic suicide for any of the major reputable brands to do so as they are tested incessantly.
My independant point of advice
4) don't obsess over small things such as "working" protein powders. MANY,many advanced bodybuilders(not to toot my horn,myself included) have cut back their intake of protein powders in favor of whole food protein sources and have seen better results.
