    By Brian on Tuesday, January 7, 2014 08:16 AM

    Effectiveness: 9/10

    (+) Boosts Energy,Convenient,Easy To Take,First Dose Results,Good Value
    (-) Pills are sticky

    How did you use it?:Before Bed

    "I havent done a zinc test but I may be deficient. Just one of these pills for a couple nights has a noticeable effect on the standard testosterone indicators for me, skin and hair get more oily, morning 'alertness', more energy at least for part of the day even with less sleep. I cant say if it really increases strength but I like the other effects it has for me."
