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.

A Foundling's Felicity
This book or novel or whatever you may deem fit to call it has so many points in its favour that it's difficult to know where to begin. I think a rundown of a few of the myriad of characters that delight me personally might do for starters: Tom Jones - A young fellow with many "imperfections" if so they may be called, but a robust fellow with a "good heart." Prudence and what is commonly called virtue are not his strong suit - But may I remind the reader that virtue comes from the Latin word for "manliness"- Tom is certainly possessed of the word's etymological origins, if not of its modern usage (particularly in amorous matters)--And a good thing too, or we should have no story here to delight us! Squire Western- Another rambunctious character, who, for me, typifies all that is Eighteenth Century England. Every time he appeared in this book, whether it was to comment on wenching, wine, or riding to hounds a smirk would immediately cross my face followed invariably by chuckling by the end of the chapter. Henry Fielding - The author plays as much a part of the book as any of the characters with many prologues and prefaces and etc. For these, and for much of the rest of the book, I might add, the reader who has not had four years of Latin inculcated into him at an English boarding school would do well to buy the Oxford edition, which fully explains all the learned quotes - Also, as one who was thus inculcated but is inclined to laziness, the Oxford edition's notes prove extremely helpful also. Fielding also gives us a lively picture of the literary life of his time, which the Oxford footnotes do a deft job of explaining- In short, buy the Oxford edition. This review can not be comprehensive. There are simply too many characters to even make a go at encompassing them all. I'm merely describing some of the, to me, more delightful ones. The book as a whole is simply a joy to read, in its comic descriptions of all who will deign to admit that they are human, and of some priggish sorts who will not so deign. I can put it no better than Fielding Himself at the beginning of Book XV: "There are a set of religious, or rather moral writers, who teach that virtue is the certain road to happiness, and vice to misery, in this world. A very wholesome and comfortable doctrine, and to which we have but one objection, namely, that is not true." In short, this is a delightful ramble of a book which, while entertaining the reader not too attached to Sunday School, sheds light on how unvirtuous the virtuous can be, and how kind and good-natured the roguish can be as well as giving us as good a history lesson on the state of affairs in Eighteenth century England (with attention given to the Jacobite Rebellion etc.) as many a "proper" history does. Who, I ask myself, would not delight in this book? ---Well...for the priggish, there's always Jane Austen.

The Sidekick in Early-Modern Literature.
Tom Jones is probably the most influential novel in English history, pioneering elements like complex characterization, social criticism and authorial interjection. But you already knew that. What you want to know is, is this a good book for us in the 21st century. And here, it's not so clear. The dialogue is pretty brisk, and some of the exchanges (the stereotypical Whig Mrs. Western arguing with her Jacobite brother is a particular treat) are actually funny. The latter part of the novel evolves into a farce, with a dozen characters engaged in scheming against one another, while Tom and Sophia helplessly go along. Farce works better in drama, where it has a faster pace, but it's always a welcome mode of comedy. You don't see enough farces. Some of the characters are evocative (why do I picture Blifil as looking like Ted Cruz?) but some are not: Dowling is just a lawyer, and Mrs. Miller is a good woman, like thousands who have come since, and that's all there is to it. It's not as if every character needs to, or can, be a fully realized person, but the parts of the novel spent with these human plot devices do feel mechanical. But Mr. Partridge, Tom's traveling companion, is in a different category altogether, and he just poisons the parts of the novel that he features in (chiefly the middle third). Eighteenth Century literature has a depressing reliance on goofy loose-lipped sidekicks: Mr. Partridge, Hugh Strap, Humphrey Clinker, Andrew Fairservice, Friday. Sometimes they're servants, but sometimes they're just stupid friends. Part of this must be practical: It's difficult to follow a wandering hero (and why are the heroes of these novels always wandering? But that's a different question altogether) without giving him a friend to talk to. Maybe early novelists had a hard time sketching characters who didn't have a way to discuss the ongoing action. But mostly, I think this is the bad influence of Don Quixote, which was becoming increasingly popular in England during this period. Sancho Panza is OK, and he's certainly the funniest element of that leaden tome. But Mr. Partridge *is* Sancho Panza, cowardice, superstition and all, and one Sancho Panza was more than enough. You know? There's a limited number of things that a silly, selfless, lazy pal can do, and it's hard to read about the same old doofus, yet again.
