I have mixed feelings about tribex. I did a cycle a few months ago (my first) and was a bit disapointed. There were definately signs of slightly increased testosterone levels. Also, I did notice an improvement in my workout intensity / energy. However, I didn’t notice a significant increase in lean body mass or strength. Perhaps, I was expecting too much. I’ve used various “products” extensively for close to ten years. I think that I might not have given tribex a fair chance, as it obviously can’t compare to such “products.” While I can’t rave about the gains I receieved from tribex, I will definately give it another try.
