Why Sparks
Letter from the founder
Hey there,
It’s Z, the founder of Ro.
I’ve been taking Viagra for 14 years. It’s been life-changing. It unlocked a whole new level of intimacy with my wife. It’s given me new confidence in and out of the bedroom.
But ED treatments have their limitations. Most take 45-60 minutes to work. Some last longer than others. It forced me to become a human stopwatch who can count in 45-minute and 4 or 6-hour increments (not the most useful skill). Plus, I had to time my meals to make sure the medication worked consistently.
We designed Sparks to help guys get the spontaneity back. Sparks is a compounded medication, which means it’s tailored for patients who need a dosage form for easier ingestion or faster onset of action. While compounded medications aren’t FDA-approved, they can be prescribed by your provider, if appropriate.
No more timers. No more mental math. Just fast-acting treatment that lasts longer.

FAQ: Ro Sparks
How do Ro Sparks work faster than traditional ED medications like Viagra or Cialis?
Ro Sparks work faster because it is administered under the tongue. This means that the medication is absorbed directly into the bloodstream via the blood vessels under the tongue, rather than getting absorbed in the stomach.
How long do Ro Sparks take to work?
Ro Sparks are a sublingual formulation, meaning they are dissolved under the tongue. ED medications that are sublingual formulations have been shown to work in as little as 15 minutes on average.*
How long do Ro Sparks last?
Ro Sparks contain tadalafil, which lasts in the bloodstream for up to 36 hours.
How long does it take to dissolve?
For most people, it dissolves in 10 minutes on average.
Ro Sparks are very intentionally designed to dissolve under your tongue for several minutes as opposed to instantly. This maximizes the amount of medication delivered directly to your bloodstream for a faster effect, compared to rapid-dissolving or swallowed tablets which are often absorbed through your digestive tract.
How much do Sparks cost?
Sparks are $12 per dose on a monthly subscription plan. Quarterly plans also available.*
For comparison, we offer traditional 50mg generic Viagra tablets at $6 per dose and 20mg generic Cialis tablets at $44 per dose on monthly plans. These are also available in quarterly, semi-annual, and annual plans.
You may cancel your plan at any time in your Ro account. Your provider will recommend the best treatment regimen for you.
*Ro offers a range of plans from 4 to 10 doses of Sparks per month.
