  • Original NO2 Formula, Back by Demand: The classic stim-free nitric oxide caplet returned unchanged -- same version customers loved for pumps and steady performance.
  • Multi-Ingredient NO Stack: L-Arginine AAKG + L-Arginine HCL + Alpha-Lipoic Acid + ACTINOS + Quercetin -- targeting both NO precursors and the NOS enzyme that converts them.
  • ACTINOS NOS-Enhancing Peptide: Per the vendor, lab-tested to boost NO production in vitro by up to 950% -- addressing the rate-limiting step arginine alone doesn't.
  • Stimulant-Free: No caffeine, no stimulants. Stimulants can constrict blood vessels -- counter-productive in a NO product. Stack with a stim pre-workout if desired.
  • Supports Strength, Vascularity & Recovery: Per the vendor, clinically tested to increase strength, improve vascularity, and support muscle regeneration after intensive exercise.
  • 90 or 180 Caplets, Made in the USA: Two count options for 30 or 60 days of use.

MRI Performance NO2 Nitric Oxide is the original nitric oxide pill formula -- back by popular demand. A stimulant-free blend of L-Arginine AAKG, L-Arginine HCL, Alpha-Lipoic Acid, ACTINOS (CFM Nitro), and Quercetin designed to boost nitric oxide production, support vasodilation, and drive superior muscle pump.

Per the vendor:
• Clinically tested to increase strength
• Supports muscle regeneration after intensive exercise
• Helps improve vascularity
• Promotes nutrient flow to working muscle

How it works: L-Arginine and AAKG serve as building blocks for nitric oxide, but the rate-limiting factor is NOS (nitric oxide synthase) activity. ACTINOS is the NOS-enhancing peptide fraction, lab-tested to boost NO production in vitro by up to 950% -- creating sustained nitric oxide overflow rather than the spike-and-crash pattern of arginine alone.

Available in 90 caplets and 180 caplets. Made in the USA.

Consult your healthcare professional prior to use if you have or suspect a medical condition, including high blood pressure and a history of cold sores, are taking prescription drugs, or have allergies to arginine, corn or citrus fruit. Do not use if pregnant or lactating. Not intended for anyone under 18.

Q: What does the ACTINOS ingredient do?
A: ACTINOS is a NOS-enhancing peptide fraction derived from whey protein isolate. NOS (nitric oxide synthase) is the enzyme that converts arginine into nitric oxide and is the rate-limiting factor in NO production. Per the vendor, ACTINOS is lab-tested to boost NO production by up to 950% in vitro.

Q: Is this the original formula?
A: Yes -- back by popular demand. Same version customers loved for its powerful pumps and steady performance.

Q: Does it contain stimulants?
A: No. It's stimulant-free. Stimulants can constrict blood vessels, which is counter-productive in a nitric oxide product. Safe to stack with a stim-based pre-workout if desired.

Q: When should I take it?
A: 30 minutes before your workout for optimal blood flow and muscle pump. Follow the recommended dose on the label.

Q: Any warnings?
A: Consult your healthcare professional prior to use if you have or suspect a medical condition, including high blood pressure, a history of cold sores, are taking prescription drugs, or have allergies to arginine, corn, or citrus fruit. Not intended for anyone under 18.
