wich extract you think are the best for improuve testosterone levels?
with which product you had the best results?
thanks
I have used tribulus terrestis. My personal opinion is that it worked. I hit PR’s in the weight room shortly after I started taking the stuff. Whether or not that can be attributed to enhanced testosterone levels I don’t know. I do wonder if it could have been a psychological advantage more than a physical one. Maybe I just thought it worked so I had more confidence.
