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.
