Sermorelin Summary

Sermorelin

Sermorelin, an acetate salt, is a synthetic peptide containing 29 Amino acids. This artificial peptide (GRF 1-29 NH2) mimics the action of naturally occurring growth hormone-releasing hormone (GHRH) composed of 44 Amino acid residues.

The growth hormone-releasing hormone receptors (GHRHr) are located in the anterior pituitary gland. Sermorelin binds with these receptors to trigger the increased production and secretion of growth hormone (GH) by somatotroph cells.

As feedback mechanisms maintain the hormonal levels, the increased serum concentration of growth hormone (GH) stimulates another endogenous hormone called somatostatin, also known as growth hormone inhibiting hormone (GHIH).

Growth hormone inhibiting hormone (GHIH) initiates a negative feedback mechanism to stop the secretion of any more growth hormone (GH) by the somatotroph cells so that hormonal levels don’t overshoot.

Thus, sermorelin makes sure to keep the entire homeostatic coordination of the hypothalamus-pituitary-somatostatin intact.

Apart from this, sermorelin also improves the sleep-related circadian rhythm by reducing the production of stress hormones. This further amplifies the release of growth hormone (GH).
