I want to give one of these two pre-workout supps a try because they both contain glycocarn. I tried searching on this forum for hemo rage vs presurge unleashed as well as googling it and came up with nothing, so i thought id start a new thread and try and get some feedback from those who have tried both. Because neither product tells how much glycocarn is in their product i want to know how the "pump" compared between them, not as concerned with energy. I apologize for starting yet another this vs that thread but i just cant find any comparisons between these two products. Thanks guys!
