I was able to purchase real Jintropins while in China and it was not an easy task. Upload a pic of your Jintropins and I can compare it and tell you if they're close to being real or not. Jintropins in China are as much a controlled item as it is in the US and you can't buy them OTC. Most pharmacies don't even carry it. When you buy it, you have to meet with a GenSci rep first and they direct you to a place where you buy it and it comes with a insulated bag and ice to keep the temp low.

If you're interested in Jintropins and don't have any person in China that can get you real ones, then I would really suggest buying the Russian ones. I've done numerous blood tests comparing the results from Russian ones purchased online VS the real Jintropins I have and the results were relatively the same. Of course, there's a whole lot of debate on how legit Russian ones are, but blood tests don't lie. All Jintropins should have a serial number where you can look up online to tell you if they are real or not. (there is some speculation that batches of serial numbers were faked internally, but i'm not going to get into that).
