In my quest to understand more about proteins and which are best, I came across some interesting
info. Most of you probably haven't heard of it, but the newest and best way to measure the
quality of a protein is the PDCAAS--Protein Digestability Corrected Amino Acid Scale. Whey is
the best protein right? Not necessarily! Most of us have heard that a whey ISOLATE is best
and yes it is a very good protein but what I found out today is that a soy isolate is just as
good or even better. On the PDCAAS soy scores a 1 which is the highest rating. Furthermore,
I inquired about the fact that whey has a great deal of BCAAs and glutamine. Guess what?
soy has higher amounts of both of these. Scammed again! An instantized soy isolate that
dissolves instantly and is very bland goes for about a fourth of what a whey isolate goes for.
The WPC that most of you are using is considered a highly INFERIOR protein source. In fact, now
that I know this I am not going to offer a WPC! Soy IMPROVES kidney function unlike any other
protein, it raises HDL (good) and lowers LDL (bad) cholesterol. It is anti-carcinogenic, etc, etc.
I believe as time goes on you will start to hear more and more about soy protein. I need some
feedback. I think the best way to go is mix 50/50 an instantized whey ISOLATE and an intantized
soy isolate. Whey has a few benefits that soy doesn't offer and this you get the best of both
worlds and at a price that can't be beat. This combo would probably sell for about $5.00 per pound.
I know that what I'm saying here goes against everything that you've been told but believe me here--
I've done my research. If the above mixture is not suitable with everyone then I could offer a
whey protein isolate AND a soy isolate and you can choose. However, just carrying the mixture
is easier for me and better for you. Think about it and let me know.
Keep up the fight
