  1. Feel the pumps 4 Star Review

    This product made me eat like a bear. My muscles had gotten fuller. My strength increased also. Ppl asking me what I was on. I really didn't care about the scale all I was worrying about my image and how my clothes fit me. I wish I could take more than a four week cycle.

  5. MSTEN review 4 Star Review

    Posted by on 21st Feb 2014

    Currently on week 4 of MSTEN RX. I have to say it's going pretty well. Pumps in the gym are great I just lift whatever's in front of me. All of my lifts are going up and my endurance is way better.
    Sides for me: mild back and calf pumps nothing to crazy.

    Overall I would recommend it. Good product and a great price thanks legendary supps!! I'll be back for more!!
