There seem to be an endless series of problems plaguing modern romance. Problems that previous generations never had to experience. Everything from the abundant options on dating apps to the constant stress of FOMO make it harder for millennials to find something real. But if you're lucky enough to make it past all of those hurdles, how can you truly know you've found a strong match?

Enter Instant Chemistry.

The company offers scientific compatibility testing based on your saliva. That's right. If you and your partner each send in a vial of spit through Instant Chemistry's relationship kit, they will analyze it and get back to you with a compatibility score, according to The Guardian. All for $199.

Co-founded by geneticist Sara Seabrooke and her husband neuroscientist Ron Gonzalez, Instant Chemistry looks for different chemical and genetic variables in each person's spit in order to come up with a rating. Most couples tend to fall within an average score of between 70% and 75%. But there are the rare ones that get close to the perfect 100%, though that doesn't happen often. 

By examining serotonin, oxytocin, and dopamine, among other chemicals, Instant Chemistry can hit upon how compatible you and your partner are psychologically, neurologically, and even biologically, according to the company's website. These puzzle pieces help determine things like how long you'll stay physically attracted to each other.

And Seabrooke and Gonzalez aren't content to stop with Instant Chemistry. They envision a possible dating app that would match single users by where they live and their biological compatibility, The Guardian reported. Sounds super romantic. 

There's no shortage of ways that science has stepped in to help people understand themselves from a biological point of view. If ancestry DNA testing can reveal your "ethnic mix," why not put your mind at ease (or start searching for a new relationship) after scientifically proving whether you and your partner can go the distance?

Seabrooke did not immediately respond to Complex's request for comment.
