Sven hasn't noticed a drastic increase in fat loss, but he's on Test and HGH too so it would be difficult to narrow the results of one compound over another. Logically, however, even if there isn't direct fat loss from Cardarine, the additional stamina he's experiencing should account for more activity, which should equate to a slightly higher caloric utilization. Different people react differently to medications, but for Sven... Testosterone provides the anabolic environment, Cardarine allows him to maximize the efficiency of his training sessions, and HGH makes him recover like a Wolverine. He's thinking about sprinkling a little RAD 140 in as he's read it has a positive synergistic effect with Test. He's just never satisfied... always looking for More.
