I tried(10) with AP today(mixed in OJ) and did legs. The pump is incredible!!!!!!! My cutoff sweats are snug around my quads and my calfs are bulging with veins that were not there yesterday. Legs were quivering as I walk down the stairs leaving the gym. Went Arbys and got the large RB sandwich(46 gms protein)with some horseradish and a water and now I need a nap.
