The famous Hygetropin, the most successful product, cause lots of fake out there. So we improved the anti-scam system.
We never change our vials cap. Please be caution! The only difference from our original Hygetropin is replacing our factory name to official website under the logo, and put on an anti-counterfeit sticker on the box.
One of the most well-known fake Hygetropin, "HYGETROPIN 8IU" was printed on vials cap. They change our official website to others.
