For anyone who has the newer Jintropin kits with the textured label which acts as the seal and replaces the hologram there is an authenticity number with 12 or 16 digits. Its authenticity can be verified at this site http://www.315net.com/English/index024.htm
If you look at the label closely you will see the website listed, the one I posted in the English version.
I just discovered it so I thought I'd share, I know many of you prob know of this already.
