Product Overview


  • Amino Acid Supplement
  • Supports Peak Performance

L-Arginine and L-Citrulline are two amino acids bundled into a single powerful supplement. L-Arginine is an important factor in muscle metabolism and is a precursor for nitric oxide, which promotes increased circulation by relaxing blood vessels. L-Citrulline helps the body rid itself of ammonia, a by-product of exercise. This clearing enables the body to recover after a workout.

Suggested Use

1 tablet four times daily.

I used to buy Largi9 from Synergy because the mix with l arginine and l citrulina is known to be very good for the the blood and vains. Unfortently that product is extremly expensive in Norway, so i have tried this product, and it looks like it's doing the same job for 1/4 of the price.

Thanks for your feedback!
