17 ingredients help amp up the intensity of your workouts for the ultimate training effect!


Boost strength, power and lean mass*

2.5g Betaine  

Betaine can promote increases in power, strength, endurance and time-to-fatigue.* In one 6-week study, subjects increased their lean mass (+5.3 pounds), and decreased their fat mass (-6.4 pounds).* That’s why it’s one of our core ingredients in Pre-Workout Intensifier.  


Muscle pump*

3g L-Citrulline, 1g Arginine AKG

Arginine is the key amino acid precursor your body uses to make nitric oxide. Citrulline is included because it can increase the body's levels of Arginine better than taking Arginine itself. We supply the precursors — you supply the intense training for an incredible muscle pump.*


Delay muscular fatigue*

1.6g Beta-Alanine

Clinical studies have shown that patented CarnoSyn® Beta-Alanine helps delay muscular fatigue and can increase total work done by extending muscular endurance during high-intensity workouts.*


Enhance energy and focus*

To get stronger, you need to elevate your workout intensity while staying focused and energized from start-to-finish.

Caffeine (200 mg) amps up your workout intensity. It also has been shown to enhance sports performance, especially during sustained high-intensity exercise.*
N-Acetyl-L-Tyrosine (500 mg) is an amino acid precursor to several neurotransmitters and can help keep you focused on your workout.*
B-Vitamins are crucial for energy production and to help combat physical stress.*
Vitamin C (120 mg) is a powerful antioxidant that fights free radicals produced during exercise.*


Replenish electrolytes

Electrolytes are vital to optimal hydration. Added electrolytes such as potassium, sodium, and magnesium help replenish what is lost through sweating.* 


Creatine free

Many people like to cycle on and off creatine—so we left it out. You decide whether to add it separately or not.


Fully disclosed label

We don’t hide ingredients in proprietary blends—we fully disclose them all. (See Supplement Facts below).
