I live outside US, do you offer international shipping?

Yes, we ship internationally and once you took your sample, you can mail it back to our lab.

Please note due to custom regulations, you will need to pay the shipping fee to send your samples and we cannot offer prepaid labels outside United States.

Also you need to make sure there is no local laws prohibiting you to send your samples outside the country. We are aware of such consideration in China, however you are advised to check the law in your country of resident.
