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 it in a prime anabolic state.
TEST SUBJECTS BUILT 8.8 LBS. OF MUSCLE!
Amino 4XL SX-7 Black Onyx also contains a clinical dose of PEAK ATP. This breakthrough ingredient supports anabolic signaling by activating the mTOR pathway. It also supports normal skeletal muscle calcium influx and release, which leads to supported muscle contraction for improved performance. Finally, PEAK ATP supports vasodilation and improves blood flow to deliver more oxygen and help you push through those last few reps!
