Ro Sparks Review: Cost per Dose vs BlueChew and Generic Pills

Below: what Sparks is, what it costs at every plan size, how it compares with BlueChew, Hims mints and plain generic tablets, and who might still choose it. Ro's full plan list and record are in our Ro review.

What Ro Sparks is

Sparks combines the active ingredients of Viagra and Cialis, sildenafil and tadalafil, in one sublingual drop. Ro describes it as "a compounded treatment for erectile dysfunction (ED) that contains the active ingredients in Viagra (sildenafil) and Cialis (tadalafil) into a single sublingual drop." Its safety box adds: "Compounded drugs are permitted to be prescribed under federal law, but are not FDA-approved and do not undergo FDA safety, effectiveness, or manufacturing review." (Ro Sparks page)

The FDA's general position is the same: "Compounded drugs are not FDA-approved. This means that FDA does not verify the safety, effectiveness or quality of compounded drugs before they are marketed." (FDA: compounding questions and answers)

So Sparks pairs two well-studied drugs in a form and combination that no regulator has reviewed. The strengths in each drop are listed on Ro's pricing page; we leave doses to the prescriber.

What Sparks costs, plan by plan

Ro sells Sparks in four monthly plans, all at the same price per dose. Figures below are quoted from Ro's pricing page on October 31, 2026; the per-dose column is our arithmetic.

There is no volume discount: ten doses cost two and a half times four doses. The online visit, follow-up messaging and shipping are included, as for every Ro ED plan.

Ro Sparks vs the alternatives, per dose

The decision in one table. All prices are live from each program's own page; "compounded" means not FDA-approved.

Sparks costs about three times Ro's own entry generic per dose, and more than BlueChew's single-drug chew. It is cheaper per dose than branded Viagra by a wide margin, which is the comparison Ro's own page invites.

Ro Sparks vs BlueChew

Both are compounded and both are sold as faster alternatives to a swallowed pill. The differences:

• Ingredients. Sparks is a two-drug drop. BlueChew sells single-drug chewables (SIL, TAD, VAR) and a four-drug GOLD tablet.
• Price. BlueChew SIL and even the four-drug GOLD cost less per tablet than a Sparks dose.
• Record. The FDA sent BlueChew a warning letter on September 9, 2025 over "same active as Viagra" claims (FDA letter to BlueChew). We found no FDA warning letter naming Ro.
• Choice. Ro also sells FDA-approved generics on the same account; BlueChew sells only compounded products.

Side by side on every plan: BlueChew vs Ro.

Ro Sparks vs Hims

Hims's nearest products are its compounded Hard Mints and sildenafil chews, from $35 a month. Hims does not publish a per-dose price or the dose count for those plans, so a per-dose comparison is not possible from its pages. Hims's headline ED plans are paid upfront in full; Ro's Sparks plans bill monthly. Hims also faces a pending lawsuit filed by the FTC, Utah and California on July 29, 2026 over billing, cancellation and health data; the claims are allegations (FTC press release).

The onset claim

Ro says Sparks works "in about 15 mins on avg. after dissolving" (Ro Sparks page) and that tadalafil keeps it active for up to a day and a half. The tadalafil part has a label behind it: the Cialis label says tadalafil "was shown to improve erectile function compared to placebo up to 36 hours following dosing" (DailyMed: Cialis label). The onset figure for the drop is Ro's own; no FDA review stands behind it.

Who might choose Sparks

• Men who want one product that combines both drugs and accept that it is compounded.
• Men who dislike swallowing pills.

Who should look elsewhere: anyone who wants an FDA-approved product, or the lowest price per dose. Ro's own generic sildenafil and tadalafil, or a 90-day generic plan elsewhere, cost less. If you already have a prescription, a cash pharmacy is cheaper still; see our Cost Plus Drugs guide.
