Hi to everyone! I'd like to buy the doctor's data stool kit with parasitology x3 from regenerus lab but since i don't live in UK(i'm from North Italy) i don't know wether that company is trustworthy or not.Have you ever had any experience with them?Is it popular in UK? Also i know that the sample's containers are filled with some liquid.Does that liquid have an expiration date (the website says that the Royal Mail International Postage can take up to 2 weeks to deliver the package..) or is it just important that i send the kit back to the lab as soon as possible?(I'd use the express service of UPS so it'd take 1 at worst 1 and half day to get to the lab) It's a lot of money and i don't want to throw it away. Thanks.
