Jul 30, 2015 I honesty can't say ... I've personally run ECA as high as 100mg of E per day for weeks and felt just subtle changes (perfect diet and cardio) I've also run t3/clen/hgh .. I've tried all the OTC out there I feel... I would never try DNP, but I'm wondering there must be a perfect stack ... Even though about ECA T3/clen but I understand the taxing with doing something like this .. So hesitant this far at the end of the day diet + cardio = king !!
