Its just a less potent version of epfedrine, that has a long release time, lasts the whole day, so the kick is a lot milder.....supressess you appetite too just like ef.....
I just throw it in my early-morning-empty stomach-pre-cardio mix, along with ECA, 4g of L carnitine, 12,5 mcgs of t3, ans 10 mg of naps ...I can say I'm quite pleased with it, not droundbreaking by any means, but a nice little addition to any cutting stack..can0t hurt anyway
