What Is Saizen® Used For?

Saizen® is the prescription human growth hormone made by EMD Serono. Saizen® is prescribed as a form of growth hormone therapy, used to replace the HGH that the body fails to produce on its own. It works to stimulate skeletal growth, increase the number and size of skeletal muscle cells, influence the size and function of internal organs, and has important effects on metabolism.

Saizen® (somatropin) is available as:
Saizen lyophilized powder (to be reconstituted with Bacteriostatic Water for Injection):

In people with growth hormone deficiency, Saizen® can replace the growth hormone that the body isn’t making on its own. In clinical studies, Saizen® has been shown to stimulate linear growth and protein synthesis. These effects are primarily mediated by IGF-1 produced in the liver and also locally, while others are primarily a consequence of the direct effects of somatropin, such as improved lipid metabolism.
In addition to tissue growth, other documented benefits of Saizen® include:

Skeletal Growth
Cell Growth
Organ Growth
Increased protein metabolism
Improved carbohydrate metabolism
Improved Lipid Metabolism
Improved Mineral Metabolism – particularly resulting in an increase in bodily potassium and phosphorus levels
Improved tissue metabolism – particularly an increase in collagen production
