Liquid egg whites exist, yes. Are they the purest form of protein in the world? Well they have no carbs or fat, so in that sense yes. They will not give you any advantage over any other source of protein.
Even if you really want egg whites, you don't need to buy that crap. I buy mine at the grocery store for much less, I'm sure.
they sell 4 gallons of egg whites for 112.00.
or you could go to costco and get the same amount for about 35 dollars.
hmmmm, maybe the 77 dollar difference is in the neat case it comes in!!
Egg protein is nature's "perfect protein". But the site is real. I've ordered from them before. Huge tub of liquid egg whites that I threw into shakes. Didn't taste it at all.
Drink them stand alone.
They're not bad.
