What does Gorilla Krush taste like?

Gorilla Krush explodes with a bold orange soda flavor.

What is nitric oxide?

Nitric oxide is a vasodilator that promotes blood circulation.

What is l-citrulline?

Citrulline is an amino acid involved in nitric oxide production, which increases blood flow to working muscles.

What is creatine?

Creatine is an amino acid-like compound that optimizes energy utilization during training. It promotes muscle growth, endurance, strength, and mass.

What is betaine anhydrous? 

Betaine is a naturally occurring amino acid-like compound that supports exercise performance and endurance. “Anhydrous” refers to a substance that doesn’t have any water.

What is malic acid?

Malic acid is a fruit acid that creates energy through the metabolism of carbs and fats.

Frequently Asked Questions

What are essential amino acids?

Essential amino acids (EAAs) are amino acids that your body can’t produce enough of on its own, including leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan. EAAs support muscle growth and recovery.

What are micronized free-form amino acids?

Micronized free-form amino acids are single amino acids that are already in a pre-digested form for faster absorption by the body.

Why is nitric oxide important?

Nitric oxide plays a key role in exercise endurance because it’s a vasodilator. A vasodilator is a substance that supports the dilation of blood vessels for increased blood flow.
