Supplement Review: Extra Strength Testosterone Booster for Men

 

This is promoted as a natural testosterone booster. I tried using it over the course of a few months and never noticed a huge increase in endurance or strength,. I also noticed that after a while the tablets seemed to be getting more and more of a gritty texture which has made them a lot harder to swallow (at least for me). Hence, I canceled my Subscribe and Save subscription on Amazon.
