Yes. well it depends on what ur going to use it for, And how much ur going to take. As long as you only take the recomeneded does you should be fine. Howeaver i would strongly caution against taking more than the recomended dose. I had a buddy take that while we were over sease and he took over the recomended does ( im not shure buy how much ) and his hart exploded. but i have taken it befor for about a year got excelant results when combined with my workout. howeaver remember to drink lots of water while taking it. Good Luck.
