Beschreibung
HGH Somatropin is the 191-amino-acid recombinant human growth hormone, structurally identical to pituitary-derived GH. FDA-approved since 1985, it acts via the GH receptor (GHR) to activate JAK2/STAT5b — driving hepatic IGF-1 production — as well as MAPK/ERK and PI3K/Akt pathways. Clinically and preclinically, it is the most studied peptide hormone for body composition, bone biology, wound healing, and metabolic regulation. The landmark 1990 Rudman study in the New England Journal of Medicine established HGH as the benchmark for anti-aging research protocols.

Research Snapshot — HGH Somatropin
Schlüsselmechanismen und Signalwege
- JAK2 / STAT5b PathwayPrimary GHR signalling cascade; drives IGF-1 transcription in hepatocytes — the key anabolic mediator.
- MAPK / ERK PathwayRegulates cell proliferation and differentiation; mediates anti-apoptotic effects in muscle and liver.
- PI3K / Akt / mTORPromotes protein synthesis, glucose uptake and cell survival via the canonical anabolic kinase cascade.
- Direct LipolysisActivates hormone-sensitive lipase (HSL) in adipocytes, shifting energy substrate toward fatty acid oxidation.
- IGF-1 / IGFBP-3 InductionDrives hepatic production of IGF-1 and its binding protein — the primary downstream anabolic effectors.
- Osteoblast StimulationVia IGF-1, drives bone matrix synthesis and mineralisation — the mechanism behind GH-driven BMD increases.
Zusammenfassung der präklinischen und klinischen Forschung
| Forschungsgebiet | Wichtigste Erkenntnis | Quelle |
|---|---|---|
| Body Composition | +5–10% lean mass, −10–20% fat mass after 6 months in GH-deficient adults. | Jorgensen JO et al., 1989 — Lancet |
| Knochendichte | +4–8% BMD per year in GH-deficient adults via IGF-1-driven osteoblast stimulation. | Rosen T et al., 1997 — J Clin Endocrinol Metab |
| Wundheilung | Increased collagen synthesis by 50–100%; accelerated burn wound healing clinically. | Herndon DN et al., 1990 — Ann Surg |
| Age Reversal Markers | Rudman study: +8.8% lean mass, +1.6% BMD, +7.1% skin thickness in men over 60. | Rudman D et al., 1990 — N Engl J Med |
