Synthetic Growth hormone (HGH) is called somatropin (British:
somatrophin). hGH refers to human growth hormone and is an
abbreviation for human GH (Somatotropin) extracted from
human pituitary glands. In 1985, biosynthetic human growth
hormone replaced pituitary-derived HGH for
therapeutic use in the U.S. and elsewhere. Biosynthetic human
growth hormone, also referred to as recombinant growth
hormone, is also called somatropin and abbreviated as rhGH.
Since the mid-1990s the abbreviation HGH has begun to carry
paradoxical connotations, and now rarely refers to real GH
used for indicated purposes. See articles on GH treatment
and hGH quackery for fuller discussions of GH therapy and
the HGH issue.
