Muscle Building Nutrition's DOMINATE is another power-packed pre workout landing at 200mg caffeine:https://blog.priceplow.com/supplement-news/muscle-building-nutrition-dominate
Full 5g creatine, 2.5g betaine, and the caffeine is backed up by 100mg TeaCrine - a dose that's expensive and tough to flavor but is WELL worth the trouble! 100mg is where it's at with this stuff!
But find out for yourself. We have a contest for FIVE of them from Muscle-Building Nutrition linked above the blog post too!
