What is l-citrulline?

L-citrulline is an amino acid involved in the production of nitric oxide, which increases blood flow to working muscles.

What is CON-CRET?

CON-CRET is a concentrated form of creatine that promotes strength, endurance, and muscle mass with reduced bloating.

What is agmatine?

Agmatine is a metabolite of the amino acid l-arginine. It’s involved in the synthesis of nitric oxide and supports athletic performance.

Frequently Asked Questions

What is nitric oxide?

Nitric oxide is a vasodilator that promotes blood circulation.

What are nootropics? 

Nootropics are substances that bolster cognitive function by altering levels of certain neurotransmitters, enzymes, or hormones in the brain. 

What is citrulline malate?

Citrulline malate is a precursor to nitric oxide, which increases blood flow to working muscles and promotes greater muscle pumps and heightened energy levels.

What is beta-alanine? 

Beta-alanine is the modified version of the amino acid alanine. The body converts beta-alanine into carnosine, which supports exercise performance and endurance. 

What is betaine? 

Betaine is a naturally occurring amino acid-like compound that supports exercise performance and endurance.

• Supports exercise endurance and intensity
• Suitable for everyday fitness enthusiasts and hardcore athletes alike
• 3,000mg of l-arginine alpha-ketoglutarate per serving
• Made in the USA using ingredients that are both foreign and domestic

Arginine alpha-ketoglutarate, or AKG, is used to support nitric oxide production. Nitric oxide promotes vasodilation to increase blood and oxygen circulation throughout the body, allowing you to work out harder for longer periods of time.
