Patented NO3-T® nitrate boost with no-stim pump and hydration

Purus Labs NOXygen Capsules is a simple, no-stim performance booster that focuses on boosting nitric oxide and keeping you hydrated during workouts. Instead of cramming in a bunch of weak pump ingredients, it sticks to two solid ones in these liquid caps: 500mg sodium nitrate as NO3-T® and 1.6g glycerol. So it's not a full-blown pre-workout, but more like a targeted tool for blood flow and staying juicy.

The star here is 500mg sodium nitrate from NO3-T®, a branded nitrate from ThermoLife. Nitrate turns into nitrite and then nitric oxide through its own pathway, different from the usual citrulline-arginine route in pump supps. Once you take it, nitrate gets converted to nitrite and nitric oxide, especially when you're pushing hard and oxygen is low. Nitric oxide helps widen blood vessels—that's vasodilation—which means better blood flow to your muscles, more oxygen and nutrients getting delivered, and that full, lasting pump you're after. Studies on nitrates, like from beets or salts, show they can make workouts feel easier and boost endurance, especially in longer sessions or back-to-back efforts. 500mg is a good, solid dose—it's the main event here, but not over-the-top compared to some heavy nitrate setups.

Then there's 1.6g glycerol. Glycerol acts as an osmolyte, which means it pulls in and holds onto water in your body. Pair it with enough water, and it helps keep your cells hydrated, muscles looking fuller, and performance steady—super useful for high-rep training or sweaty days.

Key Highlights

  • 500mg Sodium Nitrate as NO3-T® — this is the main driver, a real nitrate for nitric oxide that actually works, not just filler. It helps widen blood vessels through the nitrate-nitrite-NO path, making it different from basic citrulline pumps.
  • Patented NO3-T® from ThermoLife — branded nitrates are key because quality and stability can be iffy otherwise. This shows Purus Labs picked a solid, trusted source instead of some random nitrate claim.
  • 1.6g Glycerol — this stuff pulls in water to keep your muscles hydrated and full during workouts. You'll feel better pumps that last, less flatness, especially if you drink enough water with it.
  • Totally stim-free boost — no caffeine means you can use it anytime, like evenings, or add your own coffee. Way more flexible than those all-in-one pre-workouts that jack you up.
  • Smart two-ingredient setup without junk — no hiding weak doses in a long list. It's all about nitrate for flow and glycerol for hydration, a straightforward plan that makes sense for real training.
  • Easy capsule form — hate powders? These liquid caps are perfect for travel or quick use. Get your nitrate pump without mixing, flavors, or chugging a ton before the gym.
  • Fully open label, no prop blends — doses are right there, so you can check it against what you've read. In a world of hidden 'pump mixes,' this builds trust by letting you see what's really in it.
  • Works for lifting and cardio — nitrates help with pumps but also make oxygen use better for longer efforts. So it's not just for looks; it fits hypertrophy days, circuits, or tough conditioning.

Who Is This For?

  • Bodybuilders chasing hypertrophy who want fullness, veins, and better muscle feel over heavy stims. 500mg sodium nitrate as NO3-T® boosts flow, 1.6g glycerol keeps pumps dense through long reps.
  • Evening trainers needing support without caffeine messing sleep. NOXygen's nitrate and glycerol setup helps workout quality and pumps without ramping heart rate late.
  • Athletes using separate stims or coffee who want a clean pump add. Gives nitrate nitric oxide and hydration without extra caffeine or forced big pre mixes.
  • Cardio lovers and conditioning folks doing circuits, pushes, intervals, or repeats. Nitrates help oxygen use and workout ease, glycerol keeps you hydrated longer.
  • On-the-go pros and parents needing easy supps for the bag. Capsules skip mixing and mess while delivering solid NO3-T® nitrates.
  • Pump chasers who've done citrulline and want a new nitric path. NO3-T® converts nitrate to nitrite to NO, a fresh twist or stack option.

How to Use

Stick to the label serving, which is 3 liquid capsules. Take 30-45 minutes pre-workout with a big glass of water; that lets nitrate convert and glycerol grab fluids before you start. If nitrates or glycerol are new to you, try half first for gut check, then go full. Capsules mean no mixing, but water is a must—low fluids kill glycerol's benefits. Okay with a small snack if your stomach's picky, but many like it without heavy food for light pre-digestion. Stacks great with creatine, electrolytes, EAAs, or caffeine if you need energy. No cycling needed since it's stim-free, no addiction risk. Keep it cool and dry, seal tight to stay fresh.

What to Expect

Minutes 0-10: no rush since it's caffeine-free. Key is drinking water with it so glycerol and nitrate shine. Minutes 10-30: still low-key—most feel it once training hits, typical for no-stim nitrates. Minutes 30-60: here's the payoff, with muscles feeling fuller, pumps building easy, and workouts flowing smooth as support kicks in. Minutes 60-90: holds steady better than a caffeine peak; think ongoing fullness over a big hit. Days 1-7: hits right away, no buildup needed—just nail water and timing. Weeks 2-4: no loading like creatine, but regular use helps you tweak hydration and routine for even better feels.

Frequently Asked Questions

What are the active ingredients in Purus Labs NOXygen Capsules?

The current liquid-capsule formula is built around 500mg sodium nitrate as NO3-T® and 1.6g glycerol per serving. Those two ingredients define the product's purpose: nitrate-driven nitric oxide support plus glycerol-driven hydration and muscle fullness.

How many capsules are in one serving of NOXygen?

Brand-direct label information indicates a serving size of 3 liquid capsules. That yields 30 servings in a 90-capsule bottle.

Does Purus Labs NOXygen contain caffeine or stimulants?

No. Despite some metadata inconsistencies in third-party systems, the verified formula is stimulant-free and contains no caffeine. Its effects come from blood-flow support via nitrate and hydration support via glycerol, not central nervous system stimulation.

What does NO3-T® actually do?

NO3-T® is a trademarked sodium nitrate ingredient from ThermoLife. Nitrate supports nitric oxide production through the nitrate-nitrite-NO pathway, which helps promote vasodilation, blood flow, oxygen delivery, and the fuller pump sensation many users notice during training.

Is 1.6g of glycerol enough to matter?

It is a useful supporting dose, especially in a capsule format, but it is not an aggressive top-end glycerol dose. Research and high-performance hydration formulas often use more, so the glycerol here should be viewed as a helpful hydration adjunct rather than the sole reason to buy the product.

When should I take NOXygen before a workout?

Take it about 30-45 minutes before training with plenty of water. That gives the nitrate pathway time to begin working and gives glycerol the fluid environment it needs to support better hydration and muscle fullness.

Can I stack NOXygen with coffee or another pre-workout?

Yes. Because NOXygen contains no caffeine, it stacks cleanly with coffee, a stim pre-workout, creatine, electrolytes, or EAAs. Just be mindful that if your other product already contains pump ingredients, the overlap may change how the overall stack feels.

Is NOXygen better for pumps or endurance?

Both, but with nuance. Most users buy it for pumps and workout fullness, yet nitrate also has research relevance for oxygen efficiency and exercise economy, which can make it useful for conditioning and repeated-effort training as well.

Do I need to cycle Purus Labs NOXygen?

There is no specific cycling requirement because the formula is stimulant-free and not based on ingredients that create caffeine tolerance. You can use it consistently around training as long as it agrees with you and fits your hydration strategy.

Are there any allergen concerns with NOXygen?

The formula itself is straightforward, but brand-direct information notes that it is produced in a facility that processes common allergens including milk, eggs, soy, wheat, shellfish, fish, tree nuts, sesame, and peanuts. Highly sensitive individuals should consider that facility statement before use.

Perfect to fix your Epson Ink Pad Counter Issue
Exactly what I needed! My Epson ET-4700 started displaying an 'E-11' error on the display so I learned I would have to replace the ink pad. The package came with 4 ink-pad receptacles, four baggies for discarding the old ones, plastic gloves and even a miniature screwdriver to get the backing off of the printer. The hardware part was super simple to remove the old and install the new. Hit a bit of a snag with the included software(which was a link to a website)which Windows Defender kept blocking no matter what I tried, but a quick email to support they answered right away. Sent me to a link for better software and I was able to successfully get my printer working again. A+++ transaction and service. Thanks again!

Good product-May need to troubleshoot
I am giving this product five stars even though I had issues resetting my printer because it was not product fault. The maintenance box was easy to install. Based on other reviews, I was prepared for the wic reset site that looked suspicious. I will say it is legit. I purchased a reset key which I later found out that I did not need. Read further and I will explain. After I downloaded the WIC software, I spent over 2 hours troubleshooting yrying to reset my printer. I am writing this hoping that it might help others. In the end, the problem was my Wi-Fi was not recognizing the printer. When I was trying to reset it. I ended up connecting my printer via USB cable and I was immediately able to reset my printer and start printing again. I am going to list the troubleshooting steps I took, but you might want to try that first. In addition, before purchasing a reset key, they do offer a trial key. If you have never used a trial on that printer. I suggest doing this first because in the end I used the trial rather than the key that I had purchased. Here are a few additional troubleshooting steps you could try: 1. Ensure Correct Reset Key: Double-check that the reset key you purchased is for the correct model of your printer. If it's specific to another model or region, it may not work correctly. 2. Reinstall WIC Software: Uninstall and reinstall the WIC software to make sure it's functioning properly. Sometimes a corrupted installation can cause errors. 3. Run the Software as Administrator: Make sure you are running the WIC software as an administrator. Right-click on the WIC Reset tool icon and choose "Run as Administrator." 4. Disable Firewall/Antivirus Temporarily: Your firewall or antivirus software may be interfering with the connection. Temporarily disable them and try again to see if that helps. Make sure to turn it back on when finished. 5. Try a Different USB Port: If you are connecting via USB, try switching to another port. Alternatively, if you're using Wi-Fi, you might want to try a USB connection to see if that helps the software communicate with the printer. This is what worked for me. 6. Use a Different Computer: If possible, try using the reset software and key on a different computer. Sometimes system-specific issues can interfere with communication between the software and the printer. 7. Check for Firmware Updates: Ensure that your printer's firmware is up to date. If it's outdated, it might cause incompatibility with the reset tool. Be cautious, as some updates can prevent third-party reset tools from working. If none of the above works, it might be worth contacting the vendor of the reset key. They may have specific guidance or offer a replacement key if the one you purchased is faulty. Last resort would probably be to call Epson.

Perfect for my Epson 2720!
When my Epson 2720 printer pooped out on me and said my ink waste box was full, I was so sad. After watching a billion YouTube videos, I learned there are a ton of people selling new ink boxes and I had no clue which one to pick. I am the most electronically illiterate person on the planet so I just knew it wouldn't be easy for me to fix... wrong! This kit came with the new ink waste box, tools to change it out, a bag to throw the ink filled box into, instructions, and an extra pad for next time. After removing the old box, the new one slid in perfectly. Resetting the wic code was extremely easy as well! The instructions show step by step diagrams on what to do. It was a fast and simple process. It all worked out too well for me (normally it's a domino effect of chaos when I repair something) so the first print to see if it all worked was a nail biter. It printed beautifully! If you have a 2720 that needs repaired, this is the product for you!
