Just gave this a shot from the free sample I got with my conquest stack. I must say I think this stuff is powerful one pill is no joke i could even think of taking two no way. I am a huge fan of both versions of OEP and this stuff engery wise blows OEP away it was almost to much but leveled off to very nice that first hour or so I could stop moving. NOT sure i will be getting a bottle of it for every day use just yet but I do have a feeling this would be a great booster for my cardio days and I will be considering it once I am out of OEP. Just wanted to put this out there as a well done I-force I am impressed.
