Along with the NO3-T® Betaine Nitrate and efficaciously-dosed HydroMax® powdered glycerol that are cornerstones of the standard NOXygen® product, we’ve built upon that foundation with full doses of beta alanine, Vitacholine® natural choline bitartrate, and a unique blend of caffeine anhydrous and ZümXR® extended-release caffeine for smooth, sustained energy release. Rounded out by L-tyrosine and Huperzia serrata for focus and Pink Himalayan sea salt for hydration, Purus Labs’ new NOXygen® Pump Pre Workout is the most-advanced and tested formula worthy of its namesake.

NO3-T® citrulline nitrate & betaine nitrate creates a biphasic approach to oxygen delivery. These nitrates support your body’s ability to synthesize ATP (muscular energy) by using less oxygen during the process, thereby creating an oxygen sparing environment for your cells. Intuitively, this, leads to enhanced energetic performance.


Hydromax® Glycerol is an osmotic compound, much like the amino acids creatine and taurine, drawing and retaining water within muscle cells, hence volumizing them. More intramuscular water volume increases muscle size immediately, aids in mechanical advantage (lifting more weight), enhances hydration and helps prevent injury. Researchers have seen up to a 24% increase in endurance and others have observed a 5% increase in power or work.


VitaCholine® is the gold standard in choline salts and is the premier source of choline. Choline is an essential nutrient for health, first recognized by the Institute of Medicine in 1998. Recent studies indicate that more than 90% of people aren’t getting enough choline from diet alone. Choline is necessary to make acetylcholine, an important neurotransmitter involved in memory, muscle movement, regulating heartbeat and other basic functions.


zümXR® Extended Release Caffeine offers a controlled release rate, increasing the bioavailability of stabilized caffeine.


Huperzia Serrata Extract aids in increased cognitive functioning.


Beta Alanine helps to improve athletic performance and increase lean muscle mass.


L-Tyrosine has proved an effective aid in increasing mental performance, alertness & memory.


Mix 1 serving with 8-10 fl. oz. of cold water and consume 20-30 minutes prior to training.

30 Day Money Back Guarantee: If you are not completely satisfied, Purus Labs is happy to issue a refund or exchange for your product within 30 days of purchase. We may require you to send the product back in return for your refund.

Noxygen pre workout

I’ve used it for a few days and honestly I love it. To have and still use the Noxygen additive I definitely was pumped to see Purus Labs coming and make a Noxygen pre workout. I love the fact that it’s still a clean and simple pre workout that will get the job done like the other brands but thankfully it’s not a high stim pre workout. I’m able to get good focus off of it and the pumps are awesome along but add the liquid caps of Noxygen and trust me you’ll thank me. The main reason that I also love it is I’m able to train in the evening and still able to go to sleep without any problems. I would HIGHLY recommend Noxygen to anyone looking for a great product that hits hard but won’t give you jitters.

This stuff is awesome

I generally don’t take pre, however, I’ve been needing the extra boost here lately. This stuff is super clean and doesn’t give me nervous energy. 3.2grams of beta alanine for the perfect Itch. The pumps are awesome. 10/10 recommend trying this product!
