Project AD | Proj AD NITR-OX | 24 Servings

6g Citrulline, 5g HydroMax®—stim-free pumps with hydration support.

Project AD NITR-OX is a stim-free pump and hydration mix that focuses on a straightforward plan: boost nitric oxide, increase fluid inside and outside cells, and back up muscle work with key osmolytes (stuff that helps control water balance) and electrolytes. It's not trying to be an everything-in-one pre-workout. It's made to make your training feel better – more blood flow, thicker pumps, fuller muscles, and steady performance as you go.

The star is 6,000mg of citrulline malate. That's a solid dose backed by studies for pump and performance. Citrulline turns into arginine in your kidneys better than taking arginine straight, which ramps up nitric oxide through the arginine-NO path and widens blood vessels. In real terms, that means more blood to your working muscles, better delivery of nutrients and oxygen, and a pump you feel building set after set, not just posing in the mirror afterward. The malate part helps with exercise performance in many pre-workouts, but here the citrulline dose is the main pump driver.

HydroMax® is in at 5,000mg, and that's a big deal. It's a stable 65% glycerol powder from Glanbia Nutritionals, so you get a strong glycerol hit for extra hydration and cell swelling. Glycerol acts as an osmolyte, drawing water into your blood and muscles. That helps because a pump needs fluid to work with. You end up with rounder, fuller muscles and a pump that sticks around, especially if you drink enough water. HydroMax® is better than old-school glycerol monostearate – more concentrated, stable, and easier to mix.

Taurine at 1,000mg is another good add. It's not just thrown in; it helps with cell water regulation, calcium movement, and muscle work, and it has

Key Highlights

• 6,000mg Citrulline Malate — this is the solid foundation. Citrulline boosts arginine better than taking arginine directly, cranking up nitric oxide for wider blood vessels, better flow, and a pump that grows during your workout.
• 5,000mg HydroMax® — a heavy-hitting glycerol dose using a patented 65% powder from Glanbia Nutritionals. Glycerol pulls in water for extra hydration and muscle swelling, so your muscles feel and look fuller when you're pushing hard.
• 1,000mg Taurine — a real dose, not a tiny bit. Taurine helps with water balance in cells, calcium handling, and muscle function, which fits great with glycerol and electrolytes in a pump-focused mix.
• 150mg L-Norvaline — at the usual dose for blocking arginase (the enzyme that breaks down arginine). It helps keep arginine around longer so the citrulline nitric oxide boost lasts.
• 50mg AstraGin™ — the standard dose of this absorption helper from NuLiv Science. It boosts nutrient transporters in your gut, which makes sense for a formula relying on amino acids.
• Electrolyte support built in — 120mg sodium, 185mg chloride, and 276mg potassium add real value. Pumps work better with good hydration, and these help with fluid balance, nerve signals, and muscle contractions.
• Stim-free on purpose — perfect for evenings, stim-sensitive folks, or adding to a caffeinated pre-workout. You get the body-side boost without messing with your nervous system.
• Hydration and pump team up instead of just nitric oxide hype. Citrulline improves flow, HydroMax® adds fluid, taurine manages it in cells, and electrolytes keep everything running smooth under workout stress.

Who Is This For?

• Hypertrophy fans doing high-volume push/pull/legs or body splits. The 6,000mg citrulline malate and 5,000mg HydroMax® combo is for sessions where connection, repeats, and fullness boost your training.
• Stim-sensitive folks wanting real pre-workout feel without caffeine or other buzz stuff. NITR-OX delivers flow, hydration, and pumps without jitters, fast heart, or sleep issues.
• Evening lifters needing workouts to pop after work. Stim-free means you get effects late without stims messing up bed.
• People with a caffeinated pre-workout wanting extra pumps. This fills the gap on citrulline, glycerol, or electrolytes.
• Bodybuilders in building phases needing pumps to last whole sessions. HydroMax®, taurine, sodium, potassium, chloride keep fluid balanced for ongoing fullness.
• Athletes in hot spots or heavy sweaters. Hydration and electrolytes make sense over dry stim mixes.

How to Use

Mix one level scoop in 16-24 oz cold water and drink 20-30 minutes pre-workout. Timing lets citrulline, taurine, and hydration absorb by working sets. If new to glycerol or get stomach issues, start half scoop in more water, then go full. Use a shaker – glycerol mixes better shaken, and extra water helps mix and results.

Empty stomach for quicker action, or light meal 60-90 minutes before is okay. Heavy food right before slows it. Stim-free, so stack with coffee, caffeine pills, or pre-workout for energy. Pairs awesome with creatine for more cell swelling and performance. No cycling needed – no stims. Use on training days or daily for hydration. Store sealed, cool, dry – moisture messes with glycerol powders.

What to Expect

Minutes 0-10: Mix, drink, start hydrating. No stim rush, just easy start. Minutes 10-20: Warm-up hits, formula ramps via hydration and flow, not brain buzz. Minutes 20-40: Here's where you feel it – muscles fuller, contractions cleaner, pump building set by set. Minutes 40-90: With good water, it holds strong thanks to glycerol and electrolytes, better than NO-only stuff. Days 1-7: You figure out results are best with enough water and on high-volume days. Weeks 2-4: It gets reliable as you lock in training, hydration, and stacking. It's for immediate effects, but regular use helps you max it out.

Frequently Asked Questions

Is Project AD | NITR-OX a stimulant pre-workout?

No. Based on the verified formula provided, NITR-OX is a stim-free pump formula built around 6,000mg citrulline malate, 5,000mg HydroMax®, taurine, norvaline, AstraGin™, and electrolytes. It is designed to improve blood flow, hydration, and muscular fullness rather than provide caffeine-driven energy.

How much citrulline is in NITR-OX?

Each serving provides 6,000mg of citrulline malate. That sits in the clinically relevant range for nitric oxide and exercise performance support, making it one of the most important ingredients in the formula.

Why does NITR-OX use HydroMax®?

HydroMax® is a patented 65% glycerol powder from Glanbia Nutritionals used to support hyperhydration and cell volumization. Compared with older glycerol forms, it offers better stability and concentration, which makes it a stronger choice for a serious pump formula.

How much water should I drink with this product?

More than you would with a standard pre-workout. Because HydroMax® and the electrolyte system are designed to improve hydration and pump quality, mixing it in at least 16-24 ounces of water and continuing to drink during training usually produces a better effect than using too little fluid.

Can I stack NITR-OX with a caffeinated pre-workout?

Yes. Since NITR-OX does not rely on stimulants, it pairs well with caffeine from coffee or a separate pre-workout. This is a common strategy when you want more energy and focus without sacrificing pump and hydration support.

What does taurine do in this formula?

Taurine at 1,000mg supports osmoregulation, muscle function, and calcium signaling. In practical terms, it helps the cell manage fluid effectively, which is especially useful alongside glycerol and electrolytes.

What is L-Norvaline doing here?

L-Norvaline is included at 150mg as a support ingredient for nitric oxide signaling. It is commonly used as an arginase inhibitor, which may help preserve arginine availability and support the citrulline-driven pump effect.

Should I take NITR-OX every day or only on training days?

Most users will use it on training days because the main benefits are acute: better blood flow, hydration, and workout pumps. Daily use is also fine if you prefer consistency, but unlike creatine or beta-alanine, this formula does not depend on long-term saturation to work.

Is this a good option for evening workouts?

Yes. Because it is stimulant-free, NITR-OX is especially well suited to late-day or evening training. You get the physical performance feel of a pre-workout without dragging caffeine into your sleep window.

Does NITR-OX have any formula transparency limitations?

The verified formula provided here includes specific doses for the active ingredients listed, which is useful. However, broader market research on this product has shown conflicting historical panels and proprietary blend references, so it is fair to note that transparency around this product has not always been as clean as the best fully open-label formulas in the category.
