I'm not really one for protein skakes. I think most of the protein in shakes doesn't get metabolized anyway. I came across this Korean gocery store that sells this dried squid. It's huge with pinacles. You have to grill it on a BBQ or something. You can't eat it raw or you'll get sick. It's not like the squid sashimi you get a sushi bar.
Anyway, 2oz of this particular dried squid yield 65g of protein, 0 carbs and 7g of fat. That's an incredible nutritional breakdown. I was so amazed I thought I'd share with you gentlemen.
