Methionyl Human Growth Hormone (M-HGH), also known as Somatropin, is a crucial hormone that plays a vital role in human growth and development. However, there are several synonyms used to refer to this hormone, all of which signify its importance. Some of these terms include Recombinant Human Growth Hormone (rHGH), Synthetic Human Growth Hormone (sHGH), and Biosynthetic Human Growth Hormone (bHGH). These terms are interchangeable and denote the identical synthetic version of the growth hormone naturally produced by the pituitary gland. Despite the varying terminology, the underlying substance remains consistent, making it essential for individuals with growth deficiencies to comprehend its alternative names when seeking medical assistance.
