I used Test Freak, Anabolic Freak, and GH Freak as one muscle building stack. Over the course of the product I saw strength gainz in my lifts and was very happy with my results. I felt more aggressive in the gym and my energy levels were high. My sleep at night was great even if I only got a couple hours, I still woke up feeling refreshed. During my time on the products I was still cutting weight and remaining in a caloric deficit but was able to keep my strength up and even lift heavier in some of my lifts. A great muscle building combo right here!
