A few questions on eggs here...
It is my primary source of protein...I have 6 shakes a day...but when I say shakes Im not talking about store bought...
I put 1 scoop of protein powder(simply to supplement the egg protein) 6 eggs and water...that is primarily it.
...
How much of a difference does the yolk make?
From my experience, the yolk makes the difference between from barely gaining anything (no yolk) to gaining up to 2lbs/week (6 whites, 6 yolks, three times a day).
Is it better for muscle building to keep them whole?
In my experience, yes, without a doubt in my mind!
Does that outweigh the fat or does the extra fat outweight the cholesterol issues associated with eggs?
I have learned from my nutrition class that cholesterol from food isn't what really cause bad cholesterol in the body. It's the saturated fat and trans fat from the food.
But if you want to be sure, get blood work done to check your cholesterol level.
I have been still loosing bodyfat when doing days where I use the whole egg...
It's very possible. Not sure what kind of cycle you're on, but when I was on Tren, I could eat anything and still lose body fat.
If I want to do a clean bulk is the yolk more beneficial in maximum muscle growth?
Yes, absolutely.
As a few members have mentioned, raw eggs aren't as bioavailable as cooked eggs, so you might want to consider partially cooking them to maximize the value of your egg protein.
If you want to give this a try, here is something that I found extremely easy to do:
Put in the eggs, protein powder, and using your protein scoop, mix in about half a scoop of table sugar*, and blend it all up.
Next, microwave cook that for 1-1.5 minute (depending on how strong your oven is). The eggs should still be a liquid, but it should be very hot (and cooked).
* The table sugar is used to prevent the whites/yolks from becoming overcooked and turning into a solid.
PS: If you want to improve the flavor (eggs usually taste nasty), add in a scoop of roasted peanuts, a banana, and/or a scoop of coconut milk (condensed).
And if you have time and want to try something new, just put your protein mix into the freezer for about 1.5 hour, and you will have a delicious, muscle-building ice cream.
