KEY Ingredients

Caffeine Anhydrous

Caffeine with little to no water which makes it more absorbable & potent.  
Caffeine has science backed positive effects on weight loss, increasing energy levels and suppressing appetite.


L-Citrulline

L-citrulline is an amino acid normally made by the body. The body converts L-citrulline to L-arginine, another type of amino acid. Onions and garlic are one of the few sources of citrulline, The Vegetarian Site says that garlic and onions are alliums -- the Greek word for garlic -- that help protect against diseases that affect the heart, veins and arteries. 


L-Norvaline

L-Norvaline is a derivative of the branched-chain amino acid (BCAA) valine that has been noted in research to be a mixed arginase inhibitor.



Theobromine

Taurine

Taurine is an amino sulfonic acid, but it is often referred to as an amino acid, a chemical that is a required building block of protein. Taurine is found in large amounts in the brain, retina, heart, and blood cells called platelets. The best food sources are meat and fish. 


Beta-alanine

Beta-alanine is a non-essential amino acid that is produced naturally in the body.
Beta-alanine aids in the production of carnosine. That's a compound that plays a role in muscle endurance in high-intensity exercise.

"Great Products from Iron Brothers!

This is the second time I've used the V2 Pre Workout. I stack it with the NO2 and get a great pump during my workout. Sustained energy without any of the nasty side effects. Good clean energy. Love the Iron Brothers products. Very affordable as well. I recently purchased the thermo igniter and the Test booster. I will be writing a review on those as well after I have used them for a good amount of time. Keep up the good work Iron Brothers!!!"
