Textbooks are available EVERYWHERE... 
I think you have to go way back to: Kindergarten...sadly. 
that is the issue now isn't it, if it's so available why do you have so much trouble producing it?
Well there is the case of empty head...and if you look in the mirror you'll see one - I promise.
3Now, some words could/should be taken literally ...while some should be taken as a "figure of speech" 
For ONCE you are correct.
All 3 of your statements are correct:
1 - If your blood is empty you are already dead.
2 - one the primary functions of blood is to provide nutrients to your muscles.
3 - for nutrients to be made available to your blood they must be digested first.
........................ ........
1/a - If your body is deficient in muscle building nutrients and as such that blood is in the muscle while training is INFERIOR BLOOD to my "KNS fortified BLOOD"
2/a - As 80 % of the total blood ONLY finds it's way to the muscles WHEN WE ARE ACTUALLY TRAINING - I found it is the BEST TIME to send my little arsenal of anabolic and anti-catabolic nutrients and hormones where I want them the most...when they are needed the most and when they could create KNS MAGIC!
3/a - And THAT IS WHY I use exactly what I do...
- so blood intended to go to muscles will not digress to GI track...but that is just too much for you to understand - is it?
of course you agree with me as you know i am correct.
the problem is that everything that you say is smoke and mirrors because you are trying to create an illusion.
what exactly do you mean by 'And THAT IS WHY I use exactly what I do...

- so blood intended to go to muscles will not digress to GI track' you're right i don't understand that and i would challenge ANYONE to explain it to me, including yourself btw.
don't know how much research you've done milos but i'll let you in on some free stuff, won't cost you a penny, even more blood will be available for your working muscles if you don't put anything but water in your stomach during your workout.
