I picked this up around the gym..
2 scoops protein (chocolate works great!)
2-4 tsp water, depending on size of your proteins scoop (Its 4 for 2 scoops of Pro Performance Whey)
2 packets Splenda
Mix. The "batter" should be about the consistency of cake batter. Microwave 1 minute, 15 seconds
The best way to enjoy a protein shake IMO
I even added natty PB to mine for extra fat/protein
