took 2 of these bad boys when i got up this morning, had my cup of coffee then went out and shovelled snow. the energy wasn't as insane as it was yesterday, probably because i knew what to expect...but it was pretty damned good-better than 98% of stims i have tried lately!!! shovelled snow for around an hour and a half. when i went in i had soaked 3 layers of clothes even though temp was around 18. pretty good thermo effect i would say. can't say much for appetite suppression though i was hungry as hell!!!!
