AMINO SERIES

CODE 351195 JKG

Combines micronized L-arginine with micronized citrulline, key precursors to nitric oxide (N.O.) to get you those extreme pre-workout pumps!*

GNC's Product Development Scientists were challenged to create an advanced delivery form of amino acid supplements, a critical sports nutrition component that can be used in the regimen of top athletes.

LOADED WITH 7 GRAMS OF AMINOS, BETA-ALANINE & CITRULLINE

MICRONIZED FORMULA DESIGNED TO ENHANCE FATIGUE-CONTROLLING FACTORS*

Pro Performance(R) RapidDrive(TM) Pre-Workout Amino complex feathures our most advanced RapidDrive(TM) Amino Acid technology. This formula has been scientifically designed to provide your body with the most important amino acids needed before exercise.

Supplies a 3:1:1 ration of micronized branched chain amino acids (BCAA) to help reduce protein breakdown, preserve glycogen stores and stimulate muscle protein syntheses.*

The result of these research efforts led to the creation of the RapidDrive(TM) Amino Series, a core group of superor and fast-absorbing amino acids for rapid muscle fuel.

These ingredients have been pulverized, or "micronized," from large molecules into smaller particles that are easier to absorb and facilitate fast fuel for powerful performance.* It features micronized beta-alanine which stimulates muscle carnosine levels - a key fatigue-controlling factor.*

This formula is sugar-free and stimulant-free so it can be taken any time, day or night.

This supreme amino formula is also equipped with L-carnitine to help convert fatty acids into energy and alpha-ketogluarate (AKG) which is important for amino acid availablilty and protein synthesis.*

This unique technology is much more advanced compared to regular amino acids. Because our team is dedicated to continually improving sports nutrition products, the Pro Performance(R) RapidDrive(TM) Amino Series helps you, the athlete, get fast fuel for your muscles.
