It's a time-waster and very often it turns out to be money scam. Men/women ratio is terrible (for men). It's supposed to be free, but free options don't really work. Too many fakes and freaks. Absolutely no profile verification. I am not saying that you can't find anyone serious on Chemistry, maybe you can, but it's such a time-taking process with incredibly high risks of coming across a con artist preying on your money. They send you automatic computer-generated messages. You communicate with bots, not with real women. So it's better to just stay away from this scam!
