God of War by centurion lab for my stim pwo i only use it once a week or or so
THen for other work outs i have my own powders for a pump pwo
6g citrulline, 5g betaine, 2g taurine, 1g agamtine, 1g tyrosine and 1 teaspoon salt with some quick carbs like rice for super pumps
I like heavy stims like dmaa but i know they r horrible for my heart so i only use them vary sparringly.
