What they have in common

Where they differ

The differences are in the number of actives, the format and the price per dose.

  • Four actives vs twoQuattro adds apomorphine, a dopamine agonist that acts in the brain, and vardenafil, a third PDE5 inhibitor. Sparks contains sildenafil 55 mg and tadalafil 22 mg.
  • Liquid vial vs lozengeQuattro is a liquid in a single-dose vial. Sparks is a lozenge, which Ro markets as drops.
  • Price per doseOn monthly plans, Quattro is $7.00 a dose and Sparks $12.00. On 3-month plans, Quattro is $4.67 and Sparks from $10.75.

Where Quattro differs

  • Four prescription actives. Apomorphine, sildenafil, tadalafil and vardenafil.
  • $7.00 vs $12.00 a dose on monthly plans. Quattro: $140 for 20 doses. Sparks: $48 for 4 doses up to $168 for 14.
  • $4.67 vs $10.75 a dose on 3-month plans. Quattro: $280 for 60 doses. Sparks: $129 for 12.

In short

Sparks is a two-active lozenge; Quattro is a four-active liquid that costs less per dose on both monthly and 3-month plans. Ro's smallest plan is 4 doses for $48. Quattro's smallest plan is 20 doses, so its monthly cart ($140) is larger than most. The per-dose price is where it comes out lower.

Ro Sparks details are from Ro's Sparks safety information and Ro's ED pricing page, checked October 28, 2026. Brands change formulas and prices, so check theirs before you decide.

Quattro and Ro Sparks are compounded medications. Compounded medications are not FDA-approved, and the FDA does not verify their safety, effectiveness or manufacturing quality. A prescription is only written if a licensed provider decides it is appropriate, and results vary. everslim is not a pharmacy: Quattro is compounded and dispensed by licensed US pharmacies (EPIQ Scripts, Foothills Pharmacy, Emerald Compounding).

*$4.67 a dose is the 20-dose pack on the 3-month plan: 60 doses billed $280 upfront ($93.33 a month). The 1-month plan is $140 for 20 doses. You are only charged if a provider prescribes.

Prescription ED medications are not for everyone. Do not use them if you take nitrates for chest pain or guanylate cyclase stimulators such as riociguat, because the combination can cause a dangerous drop in blood pressure. Tell your provider about every medication and supplement you take, and about any medical conditions, especially heart problems, low or high blood pressure, a recent heart attack or stroke, kidney or liver disease, or eye conditions.

Seek emergency care for an erection lasting more than 4 hours, sudden loss of vision or hearing, chest pain, fainting or severe dizziness. Common side effects can include headache, flushing, indigestion, nasal congestion, back pain, nausea and dizziness.

Timing and results vary from person to person. Your provider decides whether treatment is appropriate and at what dose. This page is general information and not medical advice.

Important safety information

The assessment made available on the EverSlim website does not create a doctor-patient relationship between the individual completing the assessment and EverSlim. EverSlim works with a network of U.S.-licensed providers that adhere to rigorous medical protocols designed for patient safety and that have established exclusionary criteria to determine whether an individual does not qualify for GLP-1s. The answers an individual provides to the EverSlim assessment consequently determine whether the individual is screened out of eligibility for GLP-1 medication, and a clinician will meet with the individual after checkout to determine whether they qualify for a prescription. Clinicians retain the decision to prescribe compounded GLP-1s to patients.

Results from compounded medications found on the EverSlim platform may vary and may be affected by an individual’s adherence to the program and their clinician’s recommendations. Compounded GLP-1s are produced in FDA-regulated facilities. Although these facilities are highly regulated, the medications are not FDA-approved or evaluated for safety, efficacy, or quality. The decision to use compounded drugs is guided by the licensed provider’s medical judgment, which is informed by a telehealth consultation and medical history.

We encourage all prospective users of compounded medications to speak with their provider about the specific risks and benefits that may come with the use of compounded medication. EverSlim does not produce compounded medications. Prescription medications are filled by licensed compounding pharmacies across the US, and each pharmacy uses its own packaging, so packaging will vary and individuals may receive medication that looks different than what is portrayed on the website or in advertising.
