Genotropin Pfizer 16 IU (5.3 mg)

Somatropin (recombinant human growth hormone, rhGH) is a synthetic version of the hormone naturally produced by the pituitary gland. Genotropin Pfizer 16 IU (5.3 mg) is a somatropin-based therapy developed by Pfizer, designed for precise and consistent dosing in clinically supervised treatment settings. It is a prescription-only medication requiring qualified medical supervision.

What Is Recombinant Human Growth Hormone (rhGH)?

Recombinant human growth hormone plays a key role in:

• Physical growth and development
• Tissue repair and regeneration
• Regulation of metabolism

When natural growth hormone production is insufficient, somatropin therapy may be prescribed to restore normal physiological function.
