Product Overview


  • Supports Peak Performance
  • Amino Acid Supplement

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 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.

Stearic acid, maltodextrin, silicified microcrystalline cellulose, modified cellulose gum, and colloidal silicon dioxide.

Great product for Muscle Development

Posted by 5237828668624035318 on Sep 09, 2016

I am really liking this brand and every supplement I have tried from them. This L-Arginine/ L-Citrulline blend is no exception. This is a another form of the popular bodybuilding supplement "Megadrox. " There are slight differences in the amounts of the different amino acids, but I have noticed tremendous gains in every area, ( my wife does too!) This is the primary tool responsible as I have been an avid 6 day + gym rat for years, and I have tried many supplements. This one works, very well! Worth the money to try it!

Not Sure

I have been using this product for 2 months and have not yet noticed any benefits. Perhaps, it's too early to comment.
