What is Jintropin?

Jintropin is a recombinant human growth hormone (somatropin) manufactured by GeneScience Pharmaceuticals (GenSci), China’s leading biotechnology company. Produced using a patented E. coli secretion expression technology, Jintropin delivers a 191 amino acid sequence identical to naturally occurring human growth hormone—the same structure recognized by the body’s own receptors.

How Jintropin works — 191aa somatropin explained

Jintropin’s 191 amino acid sequence binds to growth hormone receptors in the liver and peripheral tissues, stimulating the production of insulin-like growth factor 1 (IGF-1). This cascade drives protein synthesis, nitrogen retention, lipolysis, and cellular repair—the mechanisms that underpin its research applications in body composition, recovery, and metabolic function.
