MRM MetaMeal is by far the best price/peformance/taste deal I have ever run across. $1 a packet at 1fast400 (board sponsor), and it has a great protein blend (including egg), a ton of glutamine, and tastes amazing...it actually becomes thick, delicious and "shakey" in water.
Anyone try the InStone MRP? I got a free sample--great profile, tasty, but DAMN, you need to use about 50% more liquid than they recommend, or else you get pudding!--Seriously!!
