L-Arginine is the most important amino acid for increasing nitric oxide (NO) production, thereby helping your blood vessels expand and relax so more nutrients and blood can flow to your muscles while you crush your workout.

As such, supplementing with L-arginine results in those intense, skin-tearing pumps that you crave every time you hit the gym. But plain L-arginine just doesn’t cut it anymore...Nitrosigine® is leading a new era of NO boosters that we’ve all been waiting for.

This ingredient is a patented form of L-arginine silicate (stabilized by myo-inositol), having much more efficacy and biological potential than basic L-arginine supplements.
