Sermorelin
The active first 29 amino acids of GHRH, the shortest fragment that retains full activity, studied for natural, pulsatile growth-hormone release.
What it is
Sermorelin is a GHRH(1-29) analogue: the opening 29 amino acids of growth-hormone-releasing hormone, which is the smallest fragment of the native molecule that keeps full biological activity. It acts on the pituitary GHRH receptor to prompt the gland to release growth hormone, and is one of the longest-studied GHRH peptides in the research literature.
What the research looks at
Research on Sermorelin examines how it stimulates the pituitary to release GH in a natural pulsatile pattern, preserving the body's own feedback rhythm rather than flooding the system. Studies look at pulse frequency and amplitude, the downstream GH-IGF-1 response, and how the GHRH(1-29) fragment compares with longer or modified analogues. Supplied strictly for laboratory research use only, not for human or veterinary use.

Preparing it
The vial ships as a lyophilized powder and is reconstituted with bacteriostatic water (or sterile water for single-session work) before use. Choose a diluent volume that gives a concentration convenient to read on a U-100 syringe. See reconstitution for the method and the concentration formula for working out the diluent.
