Quick Take: From the company the brought you Testosterone UP, Irwin Naturals has a new line of supplements which they call RED. These supplements are basically remakes of their most popular formulas but are now infused with nitric oxide boosters. As such, Testosterone Up RED is designed to be both a T and pre-workout supplement. Is this 2-in-1 formula better than the original though? Find out in the review below.
- Testosterone Up RED™ is a part of Irwin Naturals’ new line of nitric oxide boosting products
- Per the Irwin Naturals website, the core ingredients of Testosterone Up RED are LJ100® and L-Citrulline. I have a few qualms with these though. Stay tuned.
- MCT Oil and L-Citrulline at 2400 mg and 1500 mg respectively are what give Testosterone Up RED a good bulk of its PWO benefits
- High quality extracts of Fenugreek, Tribulus, Beta Sitosterol, Tongkat Ali, and Asian Ginseng are what this supplement relies on for testosterone boosts
- BioPerine® to help enhance this stack’s overall bioavailability
- Prices and shipping may vary but it’s available to buy online and in retail stores including iHerb, Amazon, and the Irwin Naturals official website.
NOTE: GNC has Testosterone Up but NOT Testosterone Up RED. Also, you might save a bit of money if you place your orders from outside of the Irwin Naturals website so do make sure to check out other stores.

Testosterone Up RED – Ingredients Review
MCT oil – This has plenty of manly benefits including that for weight loss and cognition. Perhaps more importantly for Testosterone Up RED, however, are that the calories inside MCTs are more efficiently converted into energy instead of being stored as fat. As such, I think this holds tremendous dietary promise.
L-Citrulline – This is where Testosterone Up earns its RED moniker. Citrulline is popularly found in a lot of PWO bodybuilding supplements for its ability to increase nitric oxide which then results in better circulation and “gym pumps”. Furthermore, research also shows that it can increase ATP production leading to higher energy and less fatigue during exercise.
Fenugreek – Its seeds are considered culinary spices but the saponins inside it also allow this plant to spice things up in both the gym and the bedroom. In particular, it’s capable of increasing libido, growth hormone, energy, as well as muscle strength. Moreover, it’s also quite the capable natural testosterone booster.
Tribulus – Heavily advertised as a powerful testosterone, libido, and performance booster but that’s not entirely true. While it is an effective supplement for sex, research says that Tribulus “(does) not produce the large gains in strength or lean muscle mass that many manufacturers claim”.
What about Tribulus’ effect on testosterone? Are they true?
Well, it’s both and yes and no.
As per a research that studied the influence of Tribulus Terrestris on androgen metabolism in young males, the herb neither had any direct or indirect testosterone-increasing properties.
However, a similar study that did their experiment on aging males showed positive results on both total and “free” testosterone.
So, as a testosterone booster, Tribulus Terrestris works on older men (i.e., 30 years old and above) but ineffective on the younger generation who’re already brimming with testosterone.
Beta Sitosterols – Found in prostate healthy herbs such as Stinging Nettle and Saw Palmetto, beta sitosterols give these herbs their ability to inhibit the 5-alpha-reductase (5AR) enzyme. This, then, lowers levels of DHT in favor of higher testosterone.
Ginkgo – Mostly used in nootropics but because it has high concentrations of L-Arginine, it might also be capable of boosting nitric oxide.
Beet – The roots of this plant are used here on Testosterone Up RED and I think that’s wonderful. It has naturally high concentrations of Nitrate which, according to research, reduces the oxygen required for exercise, making you push the limits of your body that much further.
LJ100® (Tongkat Ali) – Perhaps more so than Tribulus and Fenugreek, this herb is legendary when it comes to boosting male libido. More than that though, it also boosts testosterone while lowering cortisol. These effects essentially make it useful for bodybuilding, too.
Cayenne – Increasing thermogenesis while restricting appetite, this spice not only helps flavour your food but helps you lose weight as well.
Asian Ginseng – Otherwise known as Panax Ginseng, this might be the manliest of all its ginseng cousins. Overall though, ginseng have been known for their anti-stress and energy boosting properties for ages. Panax Ginseng, to be more specific, might also have benefits for testosterone.
- BioPerine® – Branded black pepper extract with 95% piperine, this ingredient doesn’t seem to have any benefits on testosterone and nitric oxide but it does help enhance nutrient bioavailabity.
- Ginger – Frankly, the research on ginger’s effects on male health have significant limitations. Nonetheless, it does have massive potential for boosting testosterone and sperm.
Both black pepper and ginger also have the ability to increase thermogenesis. So, they can be useful for weight management, too.
Testosterone Up RED Directions
Each serving of Testosterone Up RED consist of 4 liquid soft-gels. As per Irwin Naturals’ instructions, take the four soft gels in divided doses with food and water.
P.S.: For a more immediate response, take all four softgels an hour prior to activity.
First of all, Irwin Naturals says that Testosterone Up RED is supposed to be designed as a 2-in-1 testosterone/nitric oxide booster. That being said, why does their most heavily dosed ingredient (MCT oil at 2400 mg) neither increase testosterone nor circulation?
On that note, they say LJ100® and L-Citrulline are this formula’s core ingredients. So, why does it feel like the formula isn’t built around these two?
Seriously, I’m scratching my head over here.
Nonetheless, Testosterone Up RED does have its benefits regardless of what I feel are marketing mishaps.
For one, this stack’s top ingredients (MCT oil and L-Citrulline), are collectively great for boosting circulation, energy, and fat burning. To me, these two ingredients are primarily what gives Testosterone Up RED its unique pre workout (PWO) angle.
Moreover, this supplement also has Ginkgo, Beet Root, and Cayenne. Although to a much lesser degree, these ingredients also provide similar performance enhancing benefits and the entire Testosterone Up RED formula is all the better for it.
When it comes to testosterone boosting, this product is all about natural herbs. Technically, it has Fenugreek, Beta Sitosterol, Tribulus, LJ100 (Tongkat Ali), and perhaps even Asian Ginseng. The good thing about this set is that they’re all scientifically backed testosterone boosters. They’re all given in high quality forms, too.
However, Asian Ginseng only has 60 mg worth of dosage and honestly, that’s far from enough. The other T boosting herbs aren’t dosed that heavily either but, in my opinion, they might still have enough to work. If they do, they can increase the strength of your muscles, sex drive, and of course, testosterone.
Testosterone Up RED Benefits: Does it Work?
As a hybrid between testosterone booster and nitric oxide booster (pre workout), I do believe it works. Unfortunately, I’m seeing Testosterone Up RED as more of the latter.
To be frank, the test boosting that this stack offers is weak compared to the T boosting elites of 2018. So, if you’re primary aim is boosting testosterone, I suggest you look elsewhere. As a pre workout supplement, however, it offers increased circulation for better pumps, energy so you can push yourself in the gym, and a bit of fat burning to help keep those growing muscles lean. Oh, and it’s GREAT for boosting sexual vitality as well.
Testosterone Up RED Review Summary
- Non-proprietary – The dosages aren’t all that solid but I’m still glad Irwin Naturals didn’t hide them.
- All natural – None of that synthetic sh*t here. Plus, the ingredients are generally given in high quality, too.
- Safe – You might notice reddish hues on your urine or feces because of Beet Root but that’s nothing you should be worried about. The other ingredients don’t carry any risk for major side effects either.
- Physical enhancement – In my eyes, this is where Testosterone Up RED shines the brightest.
- Marketing Mishaps? – Maybe I’m just being petty but LJ100® isn’t prioritized as much as its being marketed. The entire formula isn’t much of a testosterone booster either.
- Weak T boosts – It can support testosterone, I’ll give it that, but I don’t think it’s anywhere near powerful.
- Weak reviews – As a brand, Irwin Naturals is known for quality. However, Testosterone Up RED, in particular, isn’t getting as much love that I expected from its customers.
- Bottle servings – One thing I haven’t discussed yet is how Testosterone Up RED only has 60 soft gels per bottle. With 4 softgels per serving, that’s only equivalent to 15 days. For a full month’s supply, you’ll need at least 120 soft gels which then doubles the amount you pay.
The Bottom Line
Overall, Testosterone Up RED is more pre workout than testosterone booster. That’s not to say that its T boosts are ineffective but, again, I don’t think it’s anywhere near powerful. Regardless, the way this stack boosts circulation, energy, and physical performance is great for when you hit the gym. Oh, and you can add more intense libido to its list of benefits, too.
