Review on 💪 M.A.S.S. Nutraceuticals Stim-Free Pre-Workout Supplement – Nitric Oxide Booster, Performance Enhancer – Caffeine and Creatine Free – Vasodilator, Vascularity, Pump by Mandy Johnson

This is not a stimulant product, but despite the fact that you won't get caffeine jitters (for those who don't have the right caffeine metabolizing enzyme like me!), they do have a solid ingredient profile. I really like the inclusion of Agmatine Sulfate, Norvaline, Nattokinase, and Vanilliamide Stearoyl. Green tea extract and nitrosigine are good stimulants. One intake I could skip is sodium - considering how many of us have electrolyte imbalances and prefer sodium over potassium, I would prefer the latter if it were included. Very few of us need MORE sodium intake in our diets. However, the capsules are GOLD in color. I guess it's not good for us, but it sure looks and feels cool drinking 8 golden caps! Really feel like royalty before you tuck under the barbell to bench press! I usually cut the dosage in half and use it in conjunction with my main pre-workout regimen. This is a good little amp.
