TweetMETAMYYOSYN® (Unique blend of milk protein isolates, caseinate, glutamine, whey protein concentrate, egg white),
Met-Rx has a good product. when everyone was on whey protein all the time, met-rx showed that having a blend of proteins gave immediate protein release with a slow and sustianing level of amino acids.
Do oyu need to spend the money on met-rx... no. do you need to purchase two (whey and casein) proteins... yes.
