It Triggers A 230% Nitric Oxide Boost That Lasts Up To 6 Hours

Your energy fades by mid-afternoon, and the round, the shift or the yard work still has hours left in it. BloodFlow-7® Nitro XXXL triggers a 230% boost in nitric oxide, helping your arteries relax and expand so more oxygen-rich blood reaches your muscles. Users report feeling it within 15 minutes. Then the effects last up to 6 hours per dose. That's 6 times longer than most other products on the market, so the lift you feel at 9 a.m. is still with you at 2 p.m.

Its Nitrosigine® Has 5 Times The Nitric Oxide Power Of Regular Arginine

Turn over the nitric oxide pill you take now. If the main ingredient is plain L-arginine, you're paying for the version this formula beats 5 to 1. Nitrosigine® bonds arginine to silicate, a mineral that helps keep blood vessels strong and elastic. That pairing delivers 5 times more nitric oxide power than traditional arginine supplements, and studies show the very first dose can raise arginine levels in 30 minutes or less. Dr. Luke Bucci, Juvenon's Chief Science Officer, points to peer-reviewed studies where Nitrosigine® reduced muscle damage by 56% and sped up recovery for up to 72 hours after a workout.

It Opens Your Arteries By 62% So The Extra Blood Gets Through

Poor circulation, low energy, no stamina. Making more nitric oxide only pays off if your vessels open wide enough to carry the flow. Trans-Resveratrol is backed by clinical studies to open arteries by 62%, speeding oxygen-rich blood through your entire circulatory system. The S7® Superfruit Blend adds 7 nutrient-rich botanicals clinically shown to ignite your body's own nitric oxide system. Then BioPerine®, a black pepper extract, increases the absorption of Nitrosigine®, S7® and Trans-Resveratrol to make all three more effective.

There's No Caffeine And No Stimulants In It

Pre-workouts and energy drinks get you going with caffeine and stimulants, then collect later: the jitters, the crash before dinner, the night spent staring at the ceiling. Nitro XXXL has no caffeine and no stimulants. The lift comes from blood flow itself, with stronger oxygen delivery to your muscles and a sharper mind, so the energy stays steady and clean. The formula was developed under Dr. Luke Bucci, PhD, Juvenon's Chief Science Officer and a certified clinical nutritionist.

Endurance highly improved!

I turned 63 years old this year. In the last 7-8 years, I have gotten very winded while skiing (Lake Tahoe) and trying to keep up with my young adult son. This past year was much different. I had been taking BloodFlow XXXL for about 6 months prior and my breathing and stamina was completely improved... Endurance highly improved!
