In addition to tissue growth, other documented benefits of Norditropin® 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
