I wrote a lot about the Chinese Growth Hormone which is very popular among bodybuilders, athletes, anti-aging adepts etc.
Underneath this article you can find the links to the articles where I explain, how the different Chinese companies are to be recognized. Jintropin was extremely popular some time ago and the boxes on the left where being sold in mass. When a product brings such high sales and profits, there are always people that counterfeit this product or try to sell fakes. The box on the left is a counterfeit (marked with an F), the box on the right is a real Jintropin box.. A counterfeit is a product that looks like the real product and also contains the same active ingredient. In this case somatropin or rhGrowth Hormone. A fake is mostly a product that looks like the original product but has no active ingredient or another active ingredient. The counterfeited products are mostly under dosed as you will notice later in this article.
