Growth hormone (GH) is a peptide hormone made by the pituitary gland. It’s a key reference point for understanding a whole class of research peptides — the growth-hormone secretagogues. Here’s a plain-English overview.
- What it is: a natural peptide hormone from the pituitary gland.
- How it’s released: in pulses, regulated by GHRH and ghrelin signals.
- Why it matters here: some research peptides act upstream of GH release.
What growth hormone is
GH is itself a peptide — a chain of amino acids — produced and released by the pituitary gland in natural bursts. Its release is governed by two main signals: GHRH (which stimulates it) and somatostatin (which restrains it), with ghrelin also playing a role.
Why it matters for research peptides
A category of research peptides called growth-hormone secretagogues is studied for how it engages those upstream signals rather than supplying GH directly. Examples include the GHRH analogue Tesamorelin and the CJC-1295 / Ipamorelin blend.
