Recombinant human growth hormone (somatropin) that binds to growth hormone receptors, activating JAK2/STAT5 signaling pathways, leading to increased IGF-1 production and subsequent anabolic, lipolytic, and anti-insulin effects.

Terminal elimination half-life of 3.9–4.1 hours following subcutaneous administration; intravenous half-life approximately 20–30 minutes due to rapid distribution.
Terminal half-life: 2.5-3.0 hours for subcutaneous administration. Clinical context: Supports once-daily dosing; levels return to baseline by 12-16 hours post-dose.
Primarily renal; >99% of absorbed dose eliminated via glomerular filtration and tubular reabsorption, with minimal biliary excretion (<1%).
Renal: >99% of administered dose excreted via kidneys as intact growth hormone and metabolites. Biliary/fecal: negligible (<1%).
