Is there a way a pharmacist or company or lab can tell if a pill is legit or if it's not the real stuff?

Question

I have this medication that I got from a iffy source, and I'm wondering if there is a lab, a pharmacist, or a special pharmacy where I can take these pills and they can some how tell if the pill is legit or not actually the real thing. I'm willing to pay for this service no matter how much it costs. I know I have seen them do it on TV, but I'm wondering what way a consumer can check the purity of the medication?

Answer 1

There are labs which can detect the ingredients of a tablet, but they aren't cheap.
