What is Genotropin?

Genotropin is the brand name for somatropin, a synthetic form of human growth hormone. Produced using recombinant DNA technology, it is biologically identical to the natural HGH produced by the human body.

Pfizer’s Genotropin is available in several formats, but the Genotropin Pen is the most popular due to its precision dosing, convenience, and ease of use. Unlike traditional vials, the pen allows patients to dial in the prescribed dose without complex preparation.

Available Pen Strengths

  • Genotropin Pen 5.3 mg (16 IU)
  • Genotropin Pen 12 mg (36 IU)

Each pen has a two-chamber cartridge keeping the lyophilized powder and solvent separate until activated. This design ensures maximum stability, potency, and safety.


How Genotropin Works

After injection, somatropin stimulates the liver and tissues to produce IGF-1 (insulin-like growth factor 1). IGF-1 mediates many therapeutic effects of HGH, including:

  • Bone growth in children and adolescents – promotes bone elongation and cartilage development
  • Muscle development – supports protein synthesis, lean muscle gain, and faster recovery
  • Fat metabolism – enhances lipolysis to improve body composition
  • Bone density – strengthens bones and reduces fracture risk
  • Skin and tissue repair – accelerates wound healing and tissue regeneration
  • Metabolic regulation – maintains glucose and lipid balance

Who Can Benefit from Genotropin Therapy?

Genotropin is prescribed for individuals with clinically diagnosed HGH deficiency, both pediatric and adult patients.

Pediatric Indications:

  • Growth hormone deficiency (GHD)
  • Turner syndrome
  • Prader-Willi syndrome
  • Children born small for gestational age (SGA) without catch-up growth
  • Idiopathic short stature (ISS)

Adult Indications:

  • Adult growth hormone deficiency (AGHD) due to pituitary disease, surgery, or radiation
  • Muscle wasting associated with chronic conditions
  • Metabolic dysfunction linked to low HGH

⚠️ Important: Genotropin should only be used under the supervision of a licensed healthcare provider.
