Water hardness is a measure of the dissolved mineral content of water. There are two types: the general hardness (GH) and carbonate hardness (KH). When keeping freshwater fish and plants, the GH and the KH of aquarium water should match their natural habitat.
Human Growth Hormone (rHGH, HGH, or GH), as the name suggests is a hormone that is responsible for the growth of the body through cell reproduction and regeneration.Also called somatropin, it is produced in the somatotropic cells in the pituitary gland.GH is primarily responsible for the proper growth of our bones, muscles and other tissues among children. Deficiency of this hormone would result in stunted growth of the human body.
