already, pfizer has stopped the production and distribution of genotropin for a period of time because too many fakes of genotropin have been made. because there are incredible fakes, especially in China, India and Bulgaria. that's why ngenla was produced. it's going to take a long time for them to fake this. that's why everyone can be at ease for the ngenla pens purchased right now because the fake news has not come out yet.It will be interesting to see if the Chinese will be able to duplicate and make a valid generic form of Ngenla.
