With countless male enhancement supplements available on the market today it seems impossible to find "the right one."

    It works ok!
    I think that Muscletech test 3x works and it does produce more energy and helps your muscles but you seem to plateau and the effects diminish on the second bottle. Still searching for a better test supplement!
