Quad by MEDVi is a prescription telehealth offer that the maker says combines four ingredients for desire, blood flow, strength, and a longer response window. Its sales page says the liquid goes under your tongue and may start in 10 to 15 minutes; published research supports questions about ED treatment and citrulline, but it does not answer how this four-ingredient finished formula will work for you.

Is Quad by MEDVi legit, or is it a scam?
MEDVi presents Quad as a clinician-prescribed treatment accessed through an online intake, followed by a clinician decision about whether a prescription is appropriate. Its terms say MEDVi operates the platform while affiliated medical professionals provide healthcare services and pharmacies may fulfill prescriptions.
That is different from an ad for an over-the-counter “male enhancement” pill. Still, a prescription is not automatic: MEDVi says a clinician decides whether to prescribe, and that if you don’t qualify you don’t pay. Read the terms and refund policy before you pay.
The page uses strong ad language, including “Ready Faster, Lasts All Weekend” and “peak rigidity guaranteed.” Those are the maker’s marketing claims, not a promise of your result. No regulator or court finding in the information here labels Quad or MEDVi a scam.
What is Quad supposed to contain?
MEDVi markets Quad as a four-part formula containing apomorphine, L-citrulline, tadalafil, and sildenafil. The product page assigns each a role: apomorphine for desire, L-citrulline for “rapid flow,” sildenafil for strength, and tadalafil for a response window of up to 36 hours.
| Listed ingredient | What MEDVi says | Amount published |
|---|---|---|
| Apomorphine | Acts through the nervous system to heighten desire and arousal | Not published |
| L-citrulline | Supports rapid flow | Not published |
| Tadalafil | Supports a response window of up to 36 hours | Not published |
| Sildenafil | Supports peak strength | Not published |
This matters because dose, directions, and the number of doses per monthly shipment are not published on the Quad page. Ask support for the prescription label, exact dose, directions, refill schedule, and number of doses before ordering.
Does MEDVi Quad really work for ED?
Quad is designed for ED, but the result depends on your health history and the clinician’s assessment. A review indexed by the National Library of Medicine describes PDE5 inhibitors as a first-line treatment option for men with diabetes and ED. That review covers treatment approaches in men with diabetes; it does not test Quad as a combined sublingual product.
L-citrulline is an amino acid involved in the body’s nitric-oxide pathway. A 2018 research review reports that supplemental L-citrulline can raise L-arginine levels and nitric-oxide synthesis. That is useful background on the ingredient, not a result for Quad. A small study summarized by the Cleveland Clinic reported improvement for some people with mild ED using L-citrulline, while also calling for further research.
If you are comparing Quad with Viagra, the meaningful comparison is not “better” in the abstract. Viagra contains sildenafil; MEDVi says Quad includes sildenafil plus three other ingredients. Your clinician can tell you whether that combination and its dose fit your history and current medicines.
What does Quad by MEDVi cost, and how long does it last?
Prices shown October 12, 2026: the Quad page says plans start at $114 per month, shown against $179 per month, with a doctor consultation, free rush shipping, and support included. The page also says bundles may cost less. Prices and bundles change, so check today’s amount and the recurring billing details at the Product Page before you order.
MEDVi says tadalafil in the formula can remain active for up to 36 hours. That is a claimed response window, not the length of a monthly supply. The number of doses in a Quad shipment is not published. Ask before checkout how many doses are included and when the next payment will be taken.
What side effects and medicine questions should you raise?
MEDVi’s intake is meant to collect health information and current medications so an affiliated clinician can decide whether treatment is appropriate. Bring up every prescription and nonprescription product you use, especially medicines for blood pressure, heart symptoms, or sexual health. Ask the clinician whether a four-ingredient treatment changes the safety picture for you.
For L-citrulline specifically, the PubMed review describes possible effects on blood pressure. The product page does not publish the ingredient amounts, so a clinician needs the actual prescription details to discuss your situation. Harvard Health notes that products promoted for ED may have serious side effects, which is one reason to use the medical evaluation rather than guessing from an ad.
What do the testimonials and ad signals mean?
The Quad page displays “Excellent 4.5 out of 5 TrustPilot,” says “Verified Results from 50,000+ Men,” and includes named testimonials. MEDVi’s wider policy says some website materials may be generated or enhanced with AI, people in advertisements may be actors or models, and testimonial images may use models for patient privacy. Treat testimonials as individual marketing stories, not as a forecast of what will happen for you.
That is also why it helps to save the checkout screen. Keep a copy of the plan name, total price, shipping promise, renewal date, and cancellation instructions. For another example of the details that matter before a health-product purchase, see this VisiVra scam check. If the checkout terms differ from the ad, pause and ask support to explain the difference in writing.
How do cancellation and refunds work?
MEDVi says you may cancel a subscription at any time by emailing hello@medvi.org or using the chat feature in the patient portal. Its policy asks that the request arrive at least 72 hours before the next billing date. It says a person disqualified for a medical reason receives a full refund.
The policy says prescription medications cannot be returned to a pharmacy for refund or reuse once ordered. It says damaged or incorrect medication should be reported immediately and may be replaced. If you already paid, send a cancellation request now, include your account email and requested effective date, and save the confirmation. If an item is damaged or incorrect, contact support immediately with the requested evidence.
What actually causes ED, and what can you do as a couple?
ED can have more than one cause. The diabetes-focused review describes nerve, blood-vessel, smooth-muscle, and hormonal changes as possible pathways in men with diabetes. Stress can also matter. A clinician can help sort out what is relevant to you rather than treating every case as the same problem.
If you are supporting a husband or partner, keep the conversation calm and practical. Ask what kind of help feels welcome, make room for the appointment and medication questions, and avoid turning one difficult night into a verdict about the relationship. The next small step is to write down current medicines, symptoms, and questions for the intake or clinician visit.
Before you order
- Ask for the exact prescription label, ingredient amounts, directions, and doses per shipment.
- Confirm today’s price, bundle terms, renewal date, and next billing date at checkout.
- Tell the clinician about all medicines and health conditions.
- Save the cancellation confirmation if you already enrolled.
