Stars Blue HGH
IGF is a research drug, it hasn't been approved by the FDA for use as a pharmaceutical and it is currently being researched for nerve tissue repair, possible burn victims, and also as a possible aid in muscle wasting for AIDS patients.

HGH Variations
There are many different analogs of IGF available, instead of mentioning them all, I will simply mention the two most common and the most effective. Regular recombinant IGF is one of the two, it is also the more expensive and the least effective. Regular IGF only has a half-life of about 10-20 minutes in the human body and is quickly destroyed, it can be combined with certain binding proteins to extend the half-life, but it is not a very simple procedure and there is a more effective and less expensive version available.

IGF-1 Long R3
Jintropin made by GeneScience is the most popular rHGH sold in China. According to IMS, an internationally recognized marketing firm, jintropin is the absolute market leader in China with just over 75% market share.

GenSci uses a proprietary technology called E.coli secretion technology which will produce a 191 amino acid sequence human growth hormone. This produces a high quality highly purified product resulting in no side effects associated with injection, such as red rash or welts at the injection site. This technology also has the advantage that growth hormone produced using secretion technology is very stable; it can be stable at 37C or 98F degrees for about 30 days. When refrigerated it can be stable for a year. .
