- Pro Performance RapidDrive BCAA 5000 features our most advanced RapidDrive amino acid technology. These branched-chain amino acids (BCAA) have been pasteurized, or ""micronized,"" from large molecules into smaller particles that are easier to absorb and deliver fast fuel for powerful performance.
- Now you can fully power your muscles to new levels for optimum performance. BCAA - leucine, isoleucine and valine - are critically important for stimulating muscle protein synthesis, reducing protein breakdown and stimulates muscle glycogen stores.
- The body uses these essential amino acids as fuel during exercise. Using Pro Performance RapidDrive BCAA 5000 can help maintain and rapidly replenish BCAA stores. Each serving supplies 5000mg of pure BCAA and mixes easily in any beverage or sports drink.
- 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.
