What the online ED companies are actually selling.

Our assessment

Sildenafil and tadalafil have been generic for years. They are the exact molecules studied in the trials that made PDE5 inhibitors first-line therapy, manufactured to FDA-approved standards, and dispensed at doses a prescriber can titrate deliberately.

This matters as a reference point. Much of the direct-to-consumer market is selling compounded reformulations of these same two molecules at a monthly subscription price, and the marketing rarely mentions that the approved version exists and is frequently cheaper.

The catch is that it requires a prescriber, and the whole appeal of the online model is not having to talk to one. That is a real convenience, and it is also precisely where the clinical value sits.

Our assessment

Take the disclosure at face value first, because Ro makes it themselves: this is a compounded product and it is not FDA-approved. Compounding is legal and legitimate — it exists so pharmacists can prepare a formulation an individual patient needs. It does not carry the manufacturing and content verification that sits behind an approved drug.

The clinically interesting part is the combination. Sildenafil and tadalafil are both PDE5 inhibitors — the same drug class, acting on the same enzyme, by the same mechanism. Putting them together is not a standard of care, is not in the American Urological Association guideline, and has not been established as a combination in randomized trials. The individual molecules are extremely well studied; this pairing of them is not.

Because both agents lower blood pressure through the same pathway, combining them is a pharmacological reason for caution rather than a reassurance. That matters most for men taking nitrates, where any PDE5 inhibitor is absolutely contraindicated, and for men on alpha-blockers, where dosing needs care.

The consultation is a questionnaire. A questionnaire cannot take your blood pressure, cannot examine you, and cannot order the blood work that would identify diabetes, a lipid problem or a testosterone deficiency. For a healthy man with a recent physical, that gap may be acceptable. For a man whose erectile dysfunction is the first sign of vascular disease, the gap is the entire diagnosis.

Our assessment

The doses here are more restrained than elsewhere in this category, and that is worth saying first. Neither component exceeds its own approved ceiling. But look at what each one is doing. Tadalafil at 20mg is exactly the maximum approved on-demand dose — there is no headroom left in it. Sildenafil at 20mg sits below the usual starting dose for erectile dysfunction; 20mg is the strength marketed three times daily for pulmonary arterial hypertension, not the 50mg most men begin ED treatment on.

So the tablet pairs a maximal dose of one PDE5 inhibitor with a low dose of another from the same class. Which raises an obvious question about the second one. The stated profile — onset in 30 to 60 minutes, lasting up to 36 hours — is a good description of tadalafil 20mg taken by itself. That is the drug people call the weekend pill precisely because of the 36-hour figure. It is not clear what 20mg of sildenafil adds to that beyond a second agent acting on the same enzyme and lowering blood pressure through the same pathway.

As with every combination on this page, no approved product does this and no randomized trial establishes the pairing. The evidence belongs to each molecule on its own.

Credit where it is due: RocketRx lists low blood pressure among the side effects on the product page and states plainly that the FDA does not verify the safety or effectiveness of compounded drugs. That is more forthcoming than a good deal of this market, and a man who reads their page carefully is reasonably well informed about what he is buying.

The consultation is the shortest we have looked at — two minutes by their own description. Two minutes is enough to ask whether you take nitrates. It is not enough to measure a blood pressure, examine anyone, or order the blood work that would find the diabetes or the testosterone deficiency underneath the symptom.

One last comparison, since price is the strongest argument for this product. At $2.18 a dose you are paying for a compounded combination whose advertised onset and duration match those of generic tadalafil 20mg — an FDA-approved medicine that a retail pharmacy will frequently dispense for less. Worth pricing both before you decide.

Our assessment

The core of this is the same construction as Ro Sparks and Rocket Rise: two PDE5 inhibitors, same class, same enzyme, same additive effect on blood pressure, in a compounded product with no approval and no trial evidence for the pairing. Everything said about that above applies here without modification.

What is different is the third ingredient, and it is worth being precise about it. Vitamin B12 has no established role in treating erectile dysfunction in a man whose B12 is normal. If a man is genuinely deficient, that is a finding worth investigating on its own terms — it can point to diet, to malabsorption, to metformin use — and the answer to it is not a pinch of it folded into a mint. Counting a vitamin as one of the three in a 3-in-1 is a marketing decision rather than a pharmacological one.

We could not verify the doses, and that gap matters more than it might sound. The whole basis on which we assessed the other combination products was comparing their published strengths against approved ceilings. Without those numbers there is no way to tell whether this sits in the restrained end of the category or the aggressive end.

The wider product line is the part that would give us most pause in a consulting room. Hims' compounded tablets are reported to be personalised from a menu that includes fluoxetine and a statin. Those are not incidental additions. Fluoxetine is an SSRI with a notably long half-life, real discontinuation effects, and — relevant here specifically — inhibition of the liver enzyme that clears both sildenafil and tadalafil, which makes it an interaction question inside a combination tablet rather than a neutral extra. A statin is prescribed on the basis of cardiovascular risk assessment and monitored with blood tests, neither of which a questionnaire performs.

In fairness, the reported per-use price is the lowest of anything on this page, and there is a coherent argument behind bundling a statin with an ED treatment: erectile dysfunction genuinely is a cardiovascular warning sign, and we say so at length elsewhere on this site. The disagreement is not about whether such a man may need a statin. It is about whether a questionnaire is the right place to decide that.

Our assessment

The individual doses here are the most modest on this page — 6mg of each PDE5 inhibitor, well under what any of the on-demand products contain. On strength alone this would be the least concerning combination we have looked at. The regimen is what moves it.

Daily tadalafil is a real, approved thing. It is licensed at 2.5mg and 5mg once daily and it is genuinely useful, particularly for men who want spontaneity or who also have benign prostatic hyperplasia. At 6mg this sits just above that approved daily ceiling, which on its own would be a minor observation.

Vardenafil is the problem. Vardenafil is an on-demand medication. It is approved at 5mg, 10mg and 20mg taken before activity, and there is no approved daily-dosing regimen for it — no licensed low dose, and no established evidence base for taking it every day indefinitely. A daily capsule containing vardenafil is therefore not a lower-dose version of an approved therapy; it is a chronic exposure to a drug that was never studied for chronic use.

Put the two together and the distinction from the rest of this page becomes clear. The on-demand combination products expose a man to two PDE5 inhibitors episodically, on the evenings he chooses. This one does it continuously. Both drugs lower blood pressure through the same pathway, and a daily regimen means that additive effect is present every day rather than occasionally — including on the days he is unwell, dehydrated, drinking, or starting a new blood-pressure medication.

The citrulline is the third of the three and, as with the vitamin elsewhere on this page, it is doing very little. Trials of L-citrulline in erectile dysfunction have used doses around 1.5 grams a day. 100mg is roughly a fifteenth of that. It is a reasonable ingredient at a token quantity.

Two pieces of the marketing deserve a closer look. Being compounded fresh for maximum potency sounds like a quality control assurance and is not one — freshness is not what verifies a drug's content, and the point of an approved product is that its potency has been tested rather than asserted. Similarly, a pharmacy operating in an FDA-registered facility is an administrative fact about the building; registration is not approval, and the phrase reads as an endorsement it is not.

The efficacy claim is the weakest part. Lasting 7 to 10 times longer is a comparative statement with no stated comparator and no cited study, and it is describing the wrong thing: PDE5 inhibitors act on erectile rigidity, not on ejaculatory latency. Multipliers of that order are the sort of figure associated with SSRIs used for premature ejaculation, which is a different drug class treating a different problem.

In fairness: the per-dose price is competitive, a 60-day money-back guarantee is more than most of this category offers, and daily low-dose PDE5 therapy is a legitimate clinical strategy when it is the approved drug at the approved dose. The objection is specific — it is to the vardenafil, and to deciding on chronic dual therapy without anyone taking a blood pressure first.

Our assessment

Start with the numbers, because they are published on the product page and they are the whole story. The maximum FDA-approved single dose of sildenafil is 100mg. The maximum on-demand dose of tadalafil is 20mg. The Extra formulation contains 110mg of sildenafil and 22mg of tadalafil — more than the approved ceiling for either drug — and it contains them together, in the same tablet, alongside two further actives.

Sildenafil and tadalafil are the same class working on the same enzyme. Combining them is not additive convenience; it is additive pharmacology, including additive blood-pressure lowering. There is no approved product that does this, and no randomized evidence establishing the combination, let alone the combination at these doses.

The third ingredient deserves particular attention. Apomorphine is a dopamine agonist. A sublingual apomorphine product for erectile dysfunction was developed and did not gain US approval; the apomorphine products approved in the United States today are indicated for Parkinson's disease, not for ED. Its well-documented effects include nausea and vomiting — pronounced enough that the injectable Parkinson's formulation is used alongside an antiemetic — together with dizziness, hypotension and syncope. That is a third agent lowering blood pressure in a tablet that already contains two.

Oxytocin is the fourth. It is a peptide hormone with no established role in treating erectile dysfunction, and peptides are poorly absorbed sublingually because they are degraded before they get anywhere. Its presence is difficult to justify on evidence.

Then the directions: half to one tablet. The patient is being asked to titrate a four-drug compound by splitting it by hand, without a measured dose of any single component and without anyone having taken his blood pressure.

We would say the same of any clinic doing this, including ours. Nothing here requires you to distrust the company — BlueChew publishes every one of these numbers openly, and states in plain terms that the FDA does not verify compounded drugs for safety, effectiveness or quality. Read their own disclosure and their own dosing table, then decide whether a twenty-minute questionnaire is the right amount of medical attention for it.
