AMPED™ Nitro

AMPED Nitro is best used 15-30 minutes before exercise and training sessions.

Anyone age 16 and older who is looking to improve energy, strength, and mental focus during a strenuous workout to better maximize training efforts.*

AMPED Power and AMPED Nitro both contain creatine, Nitrosigine®^§§, and citrulline and are both effective preworkout products. AMPED Nitro also contains caffeine, beta-alanine, and betaine for those who are little more serious about increasing muscle mass and improving performance. AMPED Power is still a great option for those who prefer a stimulant-free preworkout.

Beta-alanine, an ingredient in AMPED Nitro, may cause a mild, temporary tingling or prickly sensation in some users. This is a normal, harmless sensation and is a well-known sign that the ingredient is working. The sensation is typically felt on the face, neck, or back of the hands and should subside within 60-90 minutes after supplementation. Not everyone will feel the tingling due to individual differences and dosage sensitivity. 

The temporary tingling sensation should not be confused with an allergic reaction. As with any food or dietary supplement, if you experience symptoms of an allergic reaction, please discontinue use and seek prompt medical attention.

One serving of AMPED Nitro provides 100 milligrams of naturally sourced caffeine from tea leaves, similar to the amount of caffeine provided in a 12-ounce mug of brewed coffee. Caffeine has been shown to enhance athletic performance in various types of high-intensity exercise such as resistance training, sprinting, and team sports (1,2).* One serving of AMPED Nitro provides 100 milligrams of naturally sourced caffeine from tea leaves, similar to the amount of caffeine provided in a 12-ounce mug of brewed coffee.

Nitrosigine®^§§ is also known as inositol-stabilized arginine silicate and is a unique patented complex containing arginine, a metabolic precursor to nitric oxide. Nitrosigine has been shown to be more bioavailable than arginine alone, making it a powerful ingredient for boosting nitric oxide levels and blood flow to active muscle (3).* The benefits of Nitrosigine start in as little as 30 minutes after consuming and can last at least 3 hours. Nitrosigine has also been shown to support increases in mental acuity and focus as well as preworkout energy levels (4, 5).*
