History of development and application of Jintropin

The drug was received as part of a government order commissioned by the Chinese government. State subsidies accounted for 50% of the total project cost, the rest of the funding was provided by the investments of the Chinese scientist Lee Jin. The development was carried out in the territory of the own laboratory of Gene Science Pharmaceuticals Co. The first sample of Jintropin was released in 1998. The production and research laboratory of the synthetic analogue of growth hormone are located in the Chinese province of Chiang Chun.

The versatility and almost complete absence of any serious side effects made Jintropin highly popular, first in China, where in 2002 it became the first pharmacological drug in the country, and soon all over the world. Due to its low cost, it has gained popularity among representatives of show business and among athletes of various disciplines. There is information that Madonna uses Jintropin to maintain shape. Not without scandals. Sylvester Stallone, for example, tried to illegally introduce this drug in his luggage, but this attempt was stopped at the Australian border.

Many cases of illegal importation and further distribution of Jintropin in the United States led to the fact that in 2007 Li Jin was accused of smuggling synthetic somatotropin, the sale of which was completely prohibited in the United States. The result of this and other similar incidents was that the Chinese government decided to suspend the release of the drug. Thus, for three whole years (2007-2010), Jintropin was not produced at all.

Today synthetic somatotropin is produced and imported in limited quantities. Outside of China, it is sold exclusively by official GenSi distributors. This fact did not affect the fact that a huge number of fakes of this drug are being sold all over the world.
