Nitric Oxide

Citrulline + arginine stack for circulation, pump, and endurance

Clinical-dose precision. No taste, no mixing, no fuss.

Starter-friendlyOur verdict · for new lifters testing a caffeine-free pre-workout

Right ingredients, wrong dose. Citrulline studies use 6-8g for endurance and 3g for pump. This ships 400mg, so you'd need a half-dozen capsules to hit study doses. Use this as part of a stack, not as your sole pre-workout.

What's inside

  • L-Arginine HCl350mg

Pumps are back. L-citrulline dose is right. I skipped the jittery pre-workout scene and this does the job without the crash.

Endurance runs noticeably easier. No caffeine, no artificial colors. Two caps 30 min pre-run is the sweet spot.

Questions buyers ask

About 30 to 45 minutes before training. That gives L-citrulline time to convert and circulate.
