With Amino 4XL SX-7 Black Onyx, you get everything you want in a BCAA formula and more!

TEST SUBJECTS INCREASED STRENGTH BY 40%!

Amino 4XL™ SX-7® Black Onyx™ contains a clinically researched 4g dose of leucine, shown in a clinical study to help subjects increase their 5-rep max strength by over 40% in just 12 weeks! This study was published in the International Journal of Sports Physiology and Performance.

FEATURING 2 NOVEL FORMS OF LEUCINE

Amino 4XL™ SX-7® Black Onyx™ features two groundbreaking forms of leucine: PepForm® leucine and ActiveTR™ leucine.

L-leucine is the BCAA with the highest anabolic potential. It activates the mTOR enzyme, which amplifies protein synthesis. Amino 4XL SX-7 Black Onyx delivers L-leucine as free-form leucine, as well as PepForm® and ActiveTR™ leucine to ensure your body gets a steady supply to keep your body in a prime anabolic state.

L-leucine (as L-leucine, PepForm® leucine & ActiveTR™ leucine) :L-leucine is the BCAA with the highest anabolic potential. It activates the mTOR enzyme, which amplifies protein synthesis. The three different forms of leucine provided by Amino 4XL™ SX-7® Black Onyx™ ensure that you get a steady supply to keep your body in a prime anabolic state. In fact, a 4g dose of leucine is shown in a clinical study to help subjects increase their 5-rep max strength by over 40%.

PEAK ATP® (Adenosine 5′-triphosphate disodium) :Hard-training subjects who supplemented with PEAK ATP® in a 12-week study at a leading university increased strength more than the placebo group. Even better, these same subjects gained 8.8 lbs. of lean muscle versus the placebo group, which only gained 4.6 lbs. – that’s 90% more lean muscle!

BCAAs : Amino 4XL SX-7 Black Onyx delivers a potent BCAA ratio of 5:1:1 to ensure you get a clinically validated 4g dose of L-leucine.

Taurine :The 1g dose of taurine found in Amino 4XL SX-7 Black Onyx has been shown to increase endurance performance.

L-citrulline :A precursor to L-arginine that provides a spike to plasma arginine levels.

Electrolyte blend :Amino 4XL SX-7 Black Onyx delivers coconut water along with an electrolyte blend that helps restore electrolyte levels that are depleted during exercise.

Glutamine : The most abundant conditionally essential free amino acid in your body. It helps support increased cell volume, glycogen replenishment and protein synthesis.
