The amino acid ornithine – usually partnered with arginine – stimulates growth hormone (GH) release and is the stronger one. Some experts say that ornithine may be twice as effective as arginine at stimulating the release of GH. Natural growth hormone production often declines with age and may cause loss of lean muscle mass and an increase in bodyfat.

Also, for sporting purposes GH is an important fat burner, muscle builder and regenerating hormone. Increasing it naturally and cheaply can be a great help to transform your body. Ornithine can also help to support the immune system and the ability of the body to remove toxins, and promote muscle recovery.
