I tried to search but could not find about it. This is what it says about SomaLife gHP  - How Does It Work?

Let’s examine how the feedback loop in the human body governs the amount of HGH released into the bloodstream. HGH is released into the circulation by the anterior pituitary gland at the base of the brain. It attaches itself to receptors on cells, particularly liver cells, where it does essentially two things: it triggers the release of another smaller protein called IGF-1, and it signals the cell to regenerate and repair. The life of HGH in the circulation is very brief (1/2 life of 20 minutes), and IGF-1 much longer (1/2 life about 22 hours). It is through IGF-1 (another cell regeneration and repair signaling protein) that much of the work of HGH is done, as there are receptors or cells throughout the body for this protein too. SomaLife gHP assists and supports the release of HGH, triggering IGF-1, which brings about regeneration, repair and optimization within your body against the signs of aging.

Another area of the brain called the hypothalamus then monitors the amount of HGH in the bloodstream. When the levels of HGH in the bloodstream reach the optimum level, the hypothalamus releases another hormone called Somatostatin, which tells the pituitary to cut back on the levels of HGH that it is releasing. Somatostatin is also know as Growth Hormone Inhibiting Hormone or GHIH and is released from the pancreas, thyroid and gut. The dangerous part of injecting HGH directly into the bloodstream is that it bypasses the bodies sophisticated control system, while SomaLife gHP works within it.
