GenF20 is a high quality HGH supplement that works by using a formula that triggers and stimulates the pituitary gland to produce and secrete more HGH itself. The HGH is absorbed in the body naturally through the glandular system, just as it did when you were in your 20s.

It is simply not possible to just make an HGH supplement that would enter the bloodstream by other means than injection, because the HGH molecule is too large to pass through the walls of the digestive system. But with a "releaser" or stimulator product, your body produces the HGH itself.
