As and for a trial run, I popped two of these potent pink pills about an hour before training. Within a matter of 30 minutes, I could feel an escalation in my heart rate and a pump that started in my chest, leaving me, for lack of a better explanation, a bit breathless. Strength gains were undeniable and the pump was relentless within 75 minutes. I crushed my workout for nearly two hours and the pumps were skin splitting. I rode the swell for a good hour and change after that. From the moment I could feel the Methanol working to the point where it began to dissipate lasted about four hours. The verdict? These are mean little bastards and are definitely the real deal, Holyfield. They get a five plate rating from me. Get some.
