Stronger, harder erections
Ro Sparks include the active ingredient in Viagra (sildenafil), which increases blood flow to your penis to give you a stronger, harder erection.
Ro Sparks are designed with a 2-in-1 formula that includes the active ingredient in Cialis (tadalafil) which can stay in your system for up to 36 hours, allowing you to go round after round.
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.
No more timers. No more mental math. Just fast-acting treatment that lasts longer.
