Peptide secretagogues can be synthesized to stimulate the release of growth hormone and IGF-1.

“As a consequence people have developed peptide Therapeutics that stimulate the release of growth hormone and thereby the release of igf-1 but not by directly stimulating the growth hormone pathway typically what these peptides are are these are peptides that mimic the sorts of things that are typically released from the hypothalamus onto the pituitary and in that way stimulate the release of growth hormone and downstream igf-1 so what these things are typically called are secretagogues these are peptide molecules that have been synthesized in a laboratory that stimulate the release of growth hormone and thereby stimulate the production of igf-1”
