Real HGH (Somatropin) brands:
The method of manufacturing HGH that is most often used now is through either Protein Secretion technology or Mouse-cell technology. Both of these means of manufacturing create HGH that is identical to the GH produced naturally in a human body.
192 amino acid sequence HGH (Somatrem)
Inclusion Body technology was the first biosynthetic form of HGH developed (known as Met-GH, Somatorm or 192 amino acid sequence HGH). When researchers first developed HGH using Inclusion Body Technology, they were comparing it to cadaver-GH. However, Met-GH was not pure GH, so met-GH produced side effects in many users. Met-GH has an additional methionyl amino acid that caused a person's body to build up antibodies against it. Some users experienced allergic reactions to met-GH, some even built up so much resistance that it neutralized the effect of the drug.
