Can hgh make my head bigger? please help?

It's possible-Yes: HGH can indeed affect the size of your head. The hormone, which is produced by the pituitary gland, normally stimulates bone and tissue growth throughout the body. If there's too much of it, the body starts to develop an abnormal amount of flesh and bone. This affects the entire body, but in some places the chemical receptors tend to be especially sensitive, like the skull,forehead, and eye brow.
