Nitric Oxide
Citrulline + arginine stack for circulation, pump, and endurance
By IngredientMD Research TeamReviewed by Marcus Reid, MPH
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.

Why we built it this way
Who it's for. New lifters testing a caffeine-free pre-workout. The Starter-friendly verdict reflects how it performs against that use case, not against the general population.
The formulation call. 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.
The leading ingredients.
- 01L-Citrulline DL-Malate at 400mg per serving.
- 02L-Arginine HCl at 350mg per serving.
- 03L-Arginine Alpha-Ketoglutarate at 50mg per serving.
Why this format. Clinical-dose precision. No taste, no mixing, no fuss.
A note for general audiences. Clinical citrulline dose for pump runs 6-8g. This is a priming layer, not the hero.
