I just got stage new man sport gameday pre with pump powder. It has DMHA which is the new kid on the block for energy. My experience is: its OK, it gets me hot and pumped, but there is nothing like DMAA so far. Anyone else experienced gameday or DMHA?! I am trying to cycle off DMAA because I have developed some high tolerance!
