Our tester David comparing four online ED treatments
Our tester ("David", 54) compared four of the most-advertised online ED treatments over 30 days.

David didn't tell his wife of 32 years why he'd stopped initiating sex.

He told us.

Six months earlier, he'd tried Viagra for the first time. It worked — but the 30-minute wait killed every spontaneous moment, and the post-dose headaches made it feel like a punishment. Cialis was hit-or-miss. At 54 and otherwise healthy, David was quietly resigning himself to a sexless second half of his marriage.

Then his Instagram feed served him an ad for Taurus CHARGE — a new "4-in-1 liquid" that promised to address what other ED meds had been missing. He was skeptical. We agreed to help him put it to the test alongside three of the most-advertised competitors: Ro Sparks, Hims Hard Mints, and BlueChew Max.

What we found surprised all of us, including the physician we consulted.

Common Questions Before We Tested

Before David agreed to test these products, he had three questions. They're the same three questions most men have about online ED treatments — and the answers shaped how we set up the trial.

Are these online ED brands legit, or just clever marketing?

David's first question was the obvious one — how is it possible to get a real prescription medication from a website? The short answer is that telehealth is now a mainstream model in US healthcare. All four brands we tested operate through US-licensed prescribing clinicians and partnered compounding or retail pharmacies, using the same FDA-regulated active ingredients dispensed in traditional doctor's offices. Where they differ is in formulation, delivery format, and price.

Is it safe to take medications prescribed by a clinician you've never met in person?

This was the question Dr. Hale wanted to answer directly. As he put it:

"For straightforward erectile dysfunction — without a complicating cardiac history or contraindicated medications — an asynchronous online evaluation is medically appropriate. The screening questions used by all four brands cover the same criteria I use in clinic. The time saved by skipping an in-person visit is real, and for many men, it's the difference between getting treatment and never bringing it up at all."
— Dr. Marcus Hale, MD

Do compounded medications work as well as brand-name Viagra or Cialis?

Compounded medications use the same FDA-approved active ingredients as their branded counterparts — the difference is in how they're combined, dosed, and delivered. A compounded sublingual liquid containing sildenafil and tadalafil is, pharmacologically, the same molecules a Pfizer Viagra tablet contains. What you pay more or less for isn't the molecule — it's the formulation, the delivery format, and the marketing budget. For most men, the active ingredient is what matters.

Our Verdict

Winner: Taurus CHARGE

4.9/5

The only product tested that addressed both physical performance AND mental arousal.

  • Fastest onset (10-15 min)
  • Most active ingredients (4-in-1 formula)
  • Most discreet delivery (sublingual liquid)
  • Tied for highest price ($12/dose)

What Actually Matters in an ED Treatment

Erectile dysfunction has two primary biological causes: reduced blood flow to the penis, and impaired arousal signaling from the brain. Most prescription ED medications — sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra) — address only the first.

They work by inhibiting an enzyme called PDE5, which relaxes blood vessels and increases blood flow. For many men, this is enough.

But for many others — particularly men over 40 — the issue isn't purely circulatory. Stress, anxiety, performance pressure, and natural changes in dopamine signaling can blunt arousal even when blood flow is medically restored.

"PDE5 inhibitors do one thing well — they improve blood flow. But they don't directly address libido or the mental side of arousal. For patients struggling with both, that's a real gap."
— Dr. Marcus Hale, MD, primary care physician

That's why the most complete ED treatments address four things, not one:

  • Physical blood flow
  • Mental arousal and dopamine signaling
  • Fast onset (so the moment isn't lost)
  • Discreet, easy delivery

How We Tested

Over 30 days, our tester used each of the four products in randomized order, with at least 72 hours between doses. We tracked four metrics: time to onset, perceived effectiveness (rated 1-10 by the tester), side effects experienced, and ease of use.

We also consulted Dr. Marcus Hale, a board-certified primary care physician with over 15 years of clinical experience treating men's sexual health concerns, to evaluate each product's formulation from a clinical perspective.

The four products tested were the most-advertised online ED treatments available without an in-person physician visit, in the most-prescribed dose offered by each brand.

Green = best in class. Tester score reflects 30-day trial assessment across effectiveness, onset, and ease of use.

How we scored each product

Each product was rated on a 1-10 scale across four dimensions: time to onset, perceived effectiveness, ease of use, and side-effect profile.

The Tester Score shown in the comparison table is a weighted average. Effectiveness was double-weighted, given its primacy for the use case. Each product was evaluated independently, with at least 72 hours between doses to allow full clearance from the prior trial.

Effectiveness was scored from David's subjective rating of physical response, duration of effect, and overall satisfaction with the experience. Side-effect profile was scored based on any adverse effects reported during or after use, with deductions for headaches, flushing, indigestion, or visual disturbance.

Methodology was reviewed by Dr. Marcus Hale prior to the trial. We did not modify scores after the trial began.

Effectiveness — Tester Notes

For ED treatments, timing matters. Most men want something that works quickly without needing to plan an hour in advance.

In testing, Taurus CHARGE and Ro Sparks were the fastest to take effect, with noticeable onset around 15 minutes. Hims Hard Mints took 30-60 minutes. BlueChew Max also required up to 60 minutes.

All four products claim effectiveness lasting up to 36 hours once active.

What David noticed

Day 4 — Taurus. "Took it sublingually around 7pm, expecting nothing dramatic. By 7:15 I noticed not just the physical response but a feeling of calm focus, like the anxiety had quietly lifted. My wife noticed too — said something felt different. We didn't talk about why."

Day 11 — Ro Sparks. "Worked. Slower start than Taurus, and I didn't feel the same calm — just the physical effect. Tablet took noticeably longer to dissolve."

Day 19 — Hims Hard Mints. "Forty-five minutes before anything happened. By the time it kicked in, the moment had passed. Mint flavor was pleasant. Effect was milder."

Day 26 — BlueChew Max. "Similar to Hims — chewable, slow onset, did the basics. Nothing surprised me, good or bad."

"What separated Taurus from the rest wasn't just performance — it was the mental component. The other three did one job. Taurus did two."
— David, tester (54)

The Apomorphine Difference

All four products contain sildenafil and tadalafil — two of the most clinically validated PDE5 inhibitors available. Together they handle the physical side of erectile function well.

But Taurus CHARGE is the only product in this comparison that also contains apomorphine, a dopamine agonist that addresses the neurological side of arousal.

Apomorphine works by activating dopamine receptors in the brain associated with sexual arousal. While sildenafil and tadalafil affect the physical mechanics of erection, apomorphine targets the signal that initiates arousal in the first place — addressing what many men experience as a "disconnect" between body and mind.

Taurus CHARGE also includes a fourth active ingredient: vardenafil, the active medication in Levitra. Vardenafil is a PDE5 inhibitor with faster onset and higher potency per milligram than sildenafil.

"Most ED products address blood flow. Taurus CHARGE is built to address both the physical and neurological sides of sexual performance. For my patients who don't fully respond to PDE5 inhibitors alone, that addition matters."
— Dr. Marcus Hale, MD

Hims Hard Mints includes vitamin B12 as a support ingredient, but clinical research has not shown a meaningful connection between B12 supplementation and improved erectile function.5

Bottom line: Taurus CHARGE is the only product in this comparison designed to support both blood flow and arousal signaling.

Convenience & Side Effects

Taurus CHARGE pulls ahead on delivery format. The product comes in a small liquid ampoule that dissolves under the tongue in about one minute. It has a mild orange-citrus taste and is small enough to be discreet — easy to take in a bathroom or hallway without explanation.

Ro Sparks is also sublingual but uses a tablet that takes up to 10 minutes to dissolve, with a noticeably more bitter taste. Hims Hard Mints and BlueChew Max are chewable tablets — easier to recognize visually and less discreet in social situations.

Side effects in our 30-day trial were minimal. David reported no adverse effects from any of the four products. Sildenafil and tadalafil are associated with a low rate of mild side effects including flushing and indigestion.6 Apomorphine, in the doses used in modern combination ED treatments, is generally well-tolerated.7

Price & Value

Hims Hard Mints are the least expensive.

Pricing varies across the four brands. Hims Hard Mints are the cheapest at approximately $7.50 per dose. BlueChew Max falls near $10. Ro Sparks and Taurus CHARGE are tied as the most expensive at around $12 per dose.

However, in our 30-day trial, Hims Hard Mints also received the lowest tester score — slower onset, milder effect, and fewer active ingredients than the more expensive options.

As Dr. Hale put it: "You're paying for the active ingredients. With Hims, you're getting fewer of them."

Taurus CHARGE costs more per dose, but delivers four medications instead of two — including the only arousal-targeting ingredient in the comparison. For men whose ED doesn't respond fully to single-mechanism treatments, that difference matters more than $4.50.

The Verdict

Our Final Recommendation

Taurus CHARGE

4.9 / 5

After 30 days of testing, Taurus CHARGE was the only product we reviewed that addressed both the physical and neurological sides of erectile dysfunction. It delivered the fastest onset, the most complete formula, and the most discreet delivery format of any product tested.

Best for: men who haven't responded fully to single-ingredient ED medications, men who want both speed and longevity in one dose, and anyone looking for a more discreet option than a chewable tablet.

Frequently Asked Questions

The active ingredients (sildenafil, tadalafil, vardenafil, and apomorphine) are FDA-approved medications. Taurus CHARGE is a compounded formulation prepared by US-licensed compounding pharmacies — common practice for combination ED treatments. Compounded medications are not individually FDA-approved as a single formula.

Most men report feeling effects within 10-15 minutes. The sublingual liquid format bypasses the digestive system, allowing the medication to enter the bloodstream faster than chewable or pill formats — which typically take 30-60 minutes.

Yes. Taurus requires a 2-minute online medical evaluation reviewed by a US-licensed clinician, typically within 24 hours. There is no in-person doctor visit required.

Taurus offers a satisfaction guarantee. If the standard formulation doesn't work for you, their clinical team can adjust dose or formulation, or you can request a refund.

No. Taurus is a cash-pay telehealth service. There's no insurance billing, no entry on your pharmacy benefits record, and no awkward in-person prescription pickup. All shipments arrive in unmarked packaging.

Moderate alcohol is generally considered compatible with PDE5 inhibitors, but you should discuss your specific situation with the reviewing clinician during your evaluation. Heavy alcohol use can interfere with both efficacy and safety.
