Metrx ECN Amped drink mix. Just about to finish the 2lb bucket that was sent to me by The Metrx Challenge, for the losers. I had to take a break from my bench press due to sorness from tossing the cast net a number of times, I have the pumped feeling in my arms all the time. I ll try another can along with Optimum Whey that was suggested to me by another member. Any one else try this crazy foaming sweetart tasting goop. ( that is with a G )
