Additional Information

Leucine is the key BCAA shown to impact muscle protein synthesis.*

These breakthrough products are designed to deliver immediate and sustained release of ingredients to help maintain benefits throughout your workout, day or night.

Nitrogen needs increase during training, and if nitrogen levels are low, your body pulls from muscle stores which can result in catabolism, poor performance and longer recovery.

Key Minerals for Protein Synthesis & Muscle Function*

The PM Matrix was designed to promote a sense of relaxation and support restful sleep with meaningful amounts of L-theanine and melatonin.*

Leucine, a key branched chain amino acid, is one of the primary nutrients in protein responsible for anabolic benefits. With the introduction of the unique, sustained-release technology, now muscle fueling leucine is released for up to six hours!
