Universal Natural Sterol Complex 180tabsstar rating 4JeffDecember 23, 2010I used this product and had pretty good results. I put on some size in my arms. i started out benching 245 4x5 and finished at 260 for 4x5. I used this product and protein so i am pretty happy with how well it worked. i didn't notice any side effects of any kind. vascularity increased in my shoulders, arms, and chest as well.
