Confluence of whole : Confluence of whole body growth is the combination of both testosterone and growth hormone acting together. The growth hormone levels during the teen years causes whole body growth and testosterone promotes secondary sexual characteristics and promotes muscle mass. So, it is the combination surges of gh and testo that do it. After 18, gh levels start falling quite significasntly.
