I’m pushing 40 too. The first time I used Tribex alone, I did 3 caps twice a day. It took to the end of the first 3 week cycle and I noticed an incredible increase in libido along with acne and oily skin. I also started feeling very energetic on only 4-5 hours sleep. It made me feel like I was 25 again. I am a believer and repeat user. However, I really haven’t noticed any dramatic body composition or strength changes. I take it for the positive effect on my libido and mood.
