Has anyone used GW-501516 and stimulants at the same time? I typically do an hour of cardio on the weekends and will hit my max heart rate 3-4 times during that hour(195bpm). To get me through the punishment I will take ACE or A,C and Phentermine with phenibut as a magnifier. These combos add about 10 more beats per minute and I understand that Cardanine(GW-501516) actually lowers heart rate while still being thermogenic. Just dont want the ticker to explode, I'm 45, 210 lbs @ 12% bodyfat and get cardiograms once a year with no issues. Any experience on this subject is appreciated...
