Reflex Nutrition ONE STOP XTREME 4.35 KG (30 Servings)

The main protein source in One Stop Xtreme in an EU sources grass-fed dairy protein blend. Made from preferentially selected undenatured ultra filtered whey protein and undenatured native milk protein providing a valuable source of micellar casein. It provides a very rich source of branched-chain amino acids, essentail amino acids and glutamine.

No serious all-in-one bodybuilding supplement would be complete without the following highly popular and highly acclaimed amino acids; pure free form L-leucine; Beta-Alanine; Betaine Anhyrdous and Taurine.
