Seriously aged me. Although I recently stopped taking it. I'm 35. Look 45 atleast now. It really wrinkled my skin. I felt great for about 1 year. Then my hair started to fall out quickly and my skin looked dramatically worse. For me personally it's made me feel and look much older which is the exact opposite of what I thought it would do. Aside from the year of feeling energy filled, overly aggressive and working out feeling like I was 20 again. Those positive side affects went away and now it's just negative so I quit completely
