Waximaize, 5 lbstar rating 5Dale F. PennimanMay 1, 2008I tried everything on the shelves but this is the best so far for sustained pumps. Don’t forget that this product also helps to increase your nutritional uptake of aminos as well. I got a huge pump with the first drink and it lasted long afterwards. Just knowing that waximase is indeed helping to shuttle extra nutrients into my muscles makes the product well worth it. Can’t wait to go to the gym again tonight!!
