Nitrosigine (Inositol-Stabilized Arginine Silicate)
Nitrosigine is an arginine silicate complex with acute evidence for improved blood-vessel dilation.
How it counts: Counts toward Pump, not the grade

Evidence summary
Research confidence: high
1.5 g single dose significantly increased flow-mediated dilation, comparably to 8 g citrulline malate, within the same acute window.
