Review on Vascular Nutrition's Comprehensive Pre-Workout Blend for Enhanced Performance by Stephanie Mann

No tremors No crashes Pure stable energy boost Great taste (also enjoyable as a drink) Increased workout I really like this product and it lives up to the label. I've tried to break down the main aspects I like about this product above. I felt like it started about 15-20 minutes after the first use. I usually drink early in the morning on an empty stomach with no problems (I usually can't drink acidic drinks without food, such as orange juice, as it irritates my stomach). Good product!
