Sermorelin vs. Full-Length GHRH
This is a useful SEO section because researchers may search for both Sermorelin and GHRH.
Sermorelin is not full-length human GHRH.
It is a synthetic peptide corresponding to the first 29 amino acids of the naturally occurring 44-amino-acid human GHRH sequence. PubChem describes it as the amidated GHRH(1-29) fragment.
