I recently received a 3 scoop sample pack of HEMO RAGE by Nutrex. I did quads today, and was better able to focus, and was pretty strong. I had a good pump, and it tasted great. I like the geranium oil in it. I will try it again soon, and give another review. So far thumbs up. Nutrex has some great new products coming out soon. Look for it. PRO GRAM is great too.
