Product Overview

Human Growth Hormone (HGH), also known as Somatropin, is a recombinant peptide hormone that mirrors the endogenous growth hormone produced by the human pituitary gland. HGH is composed of 191 amino acids (191AA) and exhibits anabolic and growth‑stimulating effects by activating growth hormone receptors across multiple tissues.

As a laboratory‑grade product, HGH‑191AA 5000 IU is supplied as a high‑purity lyophilized peptide suitable for research purposes, including in vitro studies, cell‑based assays, and endocrinology investigations. It is not formulated for clinical treatment or human therapeutic use.

Mechanism of Action (Research Context)

HGH binds to the growth hormone receptor (GHR), a cell‑surface receptor that triggers intracellular signaling pathways such as JAK2/STAT5, PI3K/AKT, and MAPK. Activation of these pathways promotes:

• Protein synthesis and nitrogen retention
• Cell proliferation and tissue growth
• Lipid metabolism and mobilization
• IGF‑1 (Insulin‑like Growth Factor‑1) production, especially from the liver

Because of these effects, HGH is widely studied in scientific research related to:

• Cellular growth and differentiation
• Muscle development models
• Bone and cartilage research
• Metabolic and endocrine signaling pathways

Key Features

📌 Recombinant Somatropin — HGH‑191AA uses recombinant DNA technology to produce a high‑fidelity peptide identical to endogenous human growth hormone.
📌 191 Amino Acid Structure — Contains the full sequence responsible for growth hormone biological activity.
📌 5000 IU Dose Vial — Provided in a research‑grade, lyophilized peptide vial with standardized biological activity units.
📌 Laboratory Use Only — Designed for scientific experiments, assays, and analysis — not for human or animal therapeutic use.

Scientific and Research Applications

Researchers commonly use HGH‑191AA 5000 IU in laboratory studies to explore:

1. Growth factor effects on cell proliferation and differentiation.
2. Endocrine signaling and receptor biology in cultured cells.
3. IGF‑1 pathways in liver or muscle cell experiments.
4. Metabolic response studies in tissue culture systems.

These applications help clarify how growth hormone influences biological systems at molecular, cellular, and physiological levels.
