Description

The Keifeitropin Pen contains 36IU (12mg) manufactured by Keifei Pharma Co. Ltd. Keifeitropin is a powerful metabolic hormone crucial for the regulation of lipids, proteins, and carbohydrates in the body.

• In children with growth deficiency, Keifeitropin stimulates linear growth and accelerates development. • In adults, it helps maintain proper body composition through increased nitrogen retention, enhanced skeletal and muscle growth, and optimized fat metabolism.

Manufacturing & Synthesis

Keifeitropin is produced using Escherichia Coli K12, which contains the pBR322 plasmid encoding a pro-hormone of 191 amino acids. The recombinant human growth hormone is then expressed through the bacterium’s outer wall. The final product is genetically engineered to mimic the amino acid sequence naturally found in the human pituitary gland.

Keifeitropin can be administered via both Pen and Syringe.

Important: Use under medical supervision and store properly to maintain product efficacy.
