Do you want to arrive at your workout with your mind focused, yourenergy up and a real pre-workout routine?
Nitrox Therapy (680g) from BioTechUSA is a drinkable powder designed to be consumed before your workout.
Its formula combines caffeine, amino acids, vitamins, minerals and added carbohydrates in a single shaker, to help you get into the best possible condition before exertion. Each dose provides 200 mg of caffeine, a dosage designed for athletes who like powerful pre-workout formulas. Caffeine helps to increase alertness and improve concentration, handy when you want to stay in your session from the first warm-up to the last rehearsal. The formula also contains L-arginine, L-citrulline and beta-alanine, three popular ingredients in pre-workout boosters. They are often sought after by body-builders, fitness enthusiasts and intense sportsmen and women who want a complete formula.
You'll also find a BCAA complex with leucine, isoleucine and valine, to complete this performance-oriented matrix. Nitrox Therapy doesn't stop there. BioTechUSA has also included essential micronutrients such as niacin, vitamin B6, magnesium, iron, zinc and chromium. Niacin, vitamin B6, iron and magnesium help reduce fatigue and contribute to normal energy metabolism. Magnesium also contributes to normal muscle function, while zinc supports normal cognitive function and protects cells against oxidative stress.
Nitrox Therapy (680g) is therefore particularly interesting if you're looking for a complete formula to structure your pre-workout routine. Whether you're on a tough legs session, an explosive upper body workout or a session where you need to be mentally present, Nitrox Therapy (680g) accompanies you with a composition designed for intense efforts.
Simple, effective and, above all, much more fun than a lukewarm coffee swallowed between two meetings.
Available in Cranberry, Peach, Tropical and Blue Grap flavors.
