Purple hardening tonic: What is it & does it actually work?
Purple hardening tonic? What's this mysterious purple tonic for men? Does that mean your ED will magically disappear if you drink this juice? What are the ingredients and recipe?
You'll read my detailed, unbiased review below but if you're looking for a simple YES or NO answer on whether to buy it, I advise you actually DON'T do it at all.
If you're reading this, you likely watched some few minutes of a long video that starts with a scene where a beautiful woman frustrated with her husband's inability to perform in bed throws tantrums and cries.
The video goes on to where the man (Jack Jordan) describes his ED struggles and then him discovering "a bizarrely simple, all-natural remedy" that rescued his marriage, reignited his sex life, and gave him back the sex drive, stamina and hardness he had in his youthful prime.
I won't go into details of the video (it's 53 minutes long) but throughout, he calls this so-called natural remedy "purple hardening tonic".
He takes you in circles until towards the end where you'll realize all the hype and teasing was about a male enhancement supplement called Nitric Boost Ultra.
I won't even share where you can buy it (because it screams SCAM) but here's everything you need to know about it, why you should avoid it and the legit alternative that's working for a lot of men with erectile dysfunction right now.
What is purple hardening tonic?
In a nutshell, it’s a purple-colored supplement powder that you mix with juice or water and drink. It supposedly “magically” eliminates erectile dysfunction, makes you hard on command, and helps you perform like a porn star in bed.
If there was such a thing, erectile dysfunction would be a thing of the past but as you'll get to know shortly, Jack Jordan (and the frustrated sex-starved woman) are actors for a marketing message that was scripted to bait and hoodwink desperate men into buying the so-called purple hardening tonic.
The simplest way to know everything in the video is scripted is to put yourself in Jack Jordan's shoes. Would a man struggling with ed show his face and narrate his struggles and inability to satisfy his wife in a video where millions of people watch? I don't know about you but I'll personally never attempt such a thing.
How the "purple hardening tonic" supposedly works?
In the video, Jack talks about Phosphodiesterase type 5 (PDE5) as the root cause of erectile dysfunction in men and how the ingredients in the tonic supposedly clear everything and give you the libido and sex drive of your 20s and 30s.
He wants you to believe this enzyme as the "clog" that blocks blood from reaching the penis for erection to happen but that's actually far from the truth.
I've searched everywhere and there's no evidence that points to PDE5 enzyme as the true root cause of erectile dysfunction.
It's therefore safe to conclude if the cause is not PDE5 enzyme blocking blood flow to the penis, the solution can't be purple hardening tonic (or if you want to call it Nitric Boost Ultra).
You'll soon read my full review (I started using it in early January and I'll soon update the results here) but it's not what you're being told in the video or the many paid reviews you'll see published online.
"purple hardening tonic" ingredients
I'll list the full ingredients below. You won't be able to make this for yourself but you can research each of the ingredients separately to see if they have any effect on erectile dysfunction.
The one thing the video got right (sort of)
Before I move on, I want to be fair about something.
Buried underneath all the theatrical nonsense in that video — the crying wife, the actor pretending to be Jack Jordan, the 53-minute runaround — there is actually a kernel of truth.
Nitric oxide and blood flow genuinely matter for erectile function. When blood vessels can't dilate properly and circulation is poor, erections suffer. That part of the story isn't made up.
The problem isn't the concept. It's that Nitric Boost Ultra has no credible science behind how it delivers on that concept.
Slapping beetroot powder and L-Arginine into a pill and calling it a "purple hardening tonic" is not the same thing as actually solving a nitric oxide problem.
So the real question becomes: is there something that actually does what the purple tonic claims to do?
What actually works for nitric oxide — and why most supplements fail
Here's something most people don't know: the way you take a nitric oxide supplement matters more than what's in it.
L-Arginine — which is in virtually every male enhancement supplement including Nitric Boost Ultra — loses up to 75% of its potency during digestion.
And after age 45, your body struggles to convert it to nitric oxide at all. So even if the ingredient works in theory, by the time it reaches your bloodstream, most of it is gone.
The bigger issue is where nitric oxide production actually starts. MIT scientists found that the first and most critical step doesn't happen in your gut at all. It happens in your mouth.
The bacteria on your tongue convert nitrates into nitric oxide — that's the trigger. If your supplement goes straight to your stomach, it's already bypassed the most important step in the whole process.
This is why beet juice, leafy greens, and standard pills and capsules consistently underperform despite the ingredients looking good on paper. The delivery method is wrong from the start.
The legit alternative: CircO2
Once I understood that, it changed what I was looking for in an alternative.
I wasn't looking for the longest ingredients list or the most dramatic marketing claims. I was looking for something that actually works with how the body produces nitric oxide — not against it.
That's what led me to CircO2, and it's the only thing I'd recommend to any man reading this.
CircO2 comes in fast-dissolving lozenges. You place one on your tongue and it starts working immediately — right where nitric oxide production actually begins.
In clinical testing, this method raised nitric oxide levels 200% within 20 minutes and increased blood flow by 34%. No pill or capsule can achieve that because no pill or capsule is designed around how the body actually works.
The formula was developed by Dr. Greg Eckel, a Naturopathic Physician with over 23 years of experience in integrative and regenerative medicine.
He's been featured on ABC, NBC and FOX and has served as President of the Board of Naturopathic Medical Examiners. That's a real person with real credentials — not an actor reading a script.
The key ingredients are ones you'll recognize from the purple tonic list, but formulated properly:
Beet Root Powder — rich in natural nitrates that open blood vessels and improve oxygen flow. Olympic athletes use it for a reason.
L-Citrulline — converts to nitric oxide more effectively than L-Arginine, especially after 45. Directly supports circulation and sexual performance.
Hawthorn Berry — enhances nitric oxide absorption so your body gets more out of every dose.
Vitamin C — acts as a catalyst for nitric oxide production and protects it from oxidative damage.
Everything I couldn't find in Nitric Boost Ultra — a qualified formulator, a delivery method backed by research, transparent ingredients with known mechanisms — CircO2 has.
It's not a miracle cure and it doesn't claim to be. But for men who want to actually support blood flow and nitric oxide levels with something that's been properly thought through, it's the most credible option I've come across.
And unlike that purple tonic, there's a real guarantee behind it.
CircO2 offers a 90-day "down to the last lozenge" money-back guarantee — meaning you can finish the entire box and still get a full refund if you're not satisfied.
That's the kind of confidence you only put behind something that actually works.
Frequently Asked Questions (FAQs)
What is purple hardening tonic?
Purple hardening tonic is a marketing name used in the long-form video ad to describe a purple-colored supplement powder called Nitric Boost Ultra. The name doesn't refer to a specific recipe or natural remedy — it's a brand term invented for the advertisement. The video presents it as an all-natural solution to erectile dysfunction, but as I cover above, the claims don't hold up to scrutiny.
What is purple hardening juice?
Same thing, different name. "Purple hardening juice" and "purple hardening tonic" are used interchangeably in the marketing video and across various paid reviews online. Both refer to Nitric Boost Ultra — a supplement powder you mix with water or juice. The purple color comes from ingredients like beetroot powder and spirulina.
Can I make purple hardening tonic at home?
The ingredients in Nitric Boost Ultra — spirulina, beetroot powder, L-Arginine, L-Citrulline and others — are all available separately. So technically you could combine them yourself. But I'd steer you away from doing that for two reasons.
First, there's limited evidence that these ingredients in this combination actually address erectile dysfunction in any meaningful way.
Second, the core problem isn't the ingredients — it's the delivery method. Mixing these into a drink still routes everything through your digestive system, bypassing the step where nitric oxide production actually starts. You'd be spending money recreating something that doesn't work particularly well to begin with.
Is purple hardening tonic a scam?
That depends on how you define scam.
The video is scripted, the characters are actors, and the scientific claims about PDE5 enzyme being the root cause of ED are not supported by evidence.
The product itself — Nitric Boost Ultra — exists and contains real ingredients, but there's no credible evidence it does what the video promises.
Whether that crosses the line into scam territory is a judgment call, but I wouldn't spend money on it.
What are the ingredients in purple hardening tonic / Nitric Boost Ultra?
The formula includes: Spirulina Powder, L-Arginine, L-Citrulline, Vitamin D, Niacin (Vitamin B3), Beetroot Powder, Ginkgo Biloba, Horny Goat Weed (Epimedium), and Dong Quai.
Some of these — particularly L-Citrulline and Beetroot — do have research supporting their role in nitric oxide production and circulation.
The issue isn't every individual ingredient. It's the formula as a whole, the delivery method, and the wildly overstated marketing claims around what they can achieve.
Does purple hardening tonic actually work for ED?
There's no clinical evidence that it does.
Some individual ingredients have been studied in relation to blood flow and circulation, but the product as a whole has no credible clinical backing.
The marketing relies entirely on a scripted story and anecdotal testimonials rather than any verifiable research.
What's the difference between Nitric Boost Ultra and CircO2?
Several things, but the most important is the delivery method.
Nitric Boost Ultra is a powder you mix into a drink — meaning it goes straight to your stomach. CircO2 is a fast-dissolving lozenge you place on your tongue, which is where nitric oxide production actually begins according to MIT research.
Beyond that: CircO2 was developed by a credentialed naturopathic physician with 23 years of clinical experience.
Nitric Boost Ultra was developed by a marketing team around an actor named Jack Jordan.
Is CircO2 safe?
CircO2 contains well-researched, natural ingredients with no stimulants and no proprietary blends — everything in the formula is listed transparently.
It's manufactured in an FDA-registered, GMP-certified facility.
As with any supplement, if you're on medication (particularly blood pressure medication) or have an underlying health condition, check with your doctor before starting. But for healthy men looking to support nitric oxide levels and circulation, it has a strong safety profile.
How long does CircO2 take to work?
Some men report feeling a difference within minutes of the first lozenge. Others notice changes over the first few days, with more pronounced benefits after one to two weeks of consistent use.
The company recommends finishing at least one full box before evaluating — and since the 90-day guarantee covers you even if the box is empty, there's no risk in doing exactly that.
