HGH-191AA

Price range: $74.00 through $222.00 / 10 Vials

HGH 191AA (Somatropin) is a high-purity, recombinant human growth hormone produced via E. coli recombinant DNA technology. It is identical in structure and function to the growth hormone naturally secreted by the human pituitary gland. It is the gold standard in research for systemic tissue regeneration, muscle growth, fat metabolism, and significant anti-aging effects.

Mechanism of Action

Direct Growth Stimulation: Binds to the Growth Hormone Receptor (GHR) on target cells, activating the JAK2/STAT5 signaling pathway to promote cell division and growth.

IGF-1 Induction: Primarily acts on the liver to stimulate the synthesis and release of Insulin-like Growth Factor 1 (IGF-1), which mediates most of the growth-promoting effects on bone and muscle.

Lipolysis & Metabolic Shift: Directly promotes the breakdown of stored triglycerides in adipocytes (fat cells) and shifts the body's energy source from glucose to fatty acids.

Tissue Repair & Anti-Aging: Enhances protein synthesis and mineral retention, leading to improved skin elasticity, faster injury recovery, and increased bone density.

Storage & handling

Storage:Store the lyophilized vial in a cool, dry area protected from direct sunlight.
