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.

Other Ingredients

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

Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.


If you are pregnant, may become pregnant, breastfeeding, have a history of heart disease, hypotension, renal or hepatic failure, or are taking any prescription medications such as nitroglycerine or any drug for erectile dysfunction, consult your physician before using this product.

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.
