Tropin 4000IU Pre-filled Injection Pen contains Somatropin, a synthetic recombinant form of human growth hormone (rHGH). It is prescribed to treat growth hormone deficiency (GHD) in children and adults, and in specific conditions like Turner’s syndrome, chronic kidney disease, and Prader-Willi syndrome.
This higher-strength 4000IU pre-filled pen allows for convenient dosing, precise administration, and reduced injection frequency. It supports growth, muscle mass, bone strength, and overall metabolism under medical supervision.
