I only purchased and checked the contents. Since the expiration date is approaching, I'm selling it at a low price. What is a genetic testing kit? It's a brand of genetic testing kits that analyze obesity genes and skin aging genes from saliva collected at home. It reveals a person's unchanging genetic constitution, and proposes diet plans and lifestyles suited to their constitution. You can test by simply swabbing the inside of your cheek with a special cotton swab and mailing it. The results are subdivided into 33 patterns, explained in an easy-to-understand way using animal analogies, and supported by an app.
