What Is Secretagogue?
Category: Pharmacology
A substance that promotes the secretion of a hormone. GH secretagogues stimulate the pituitary gland to release growth hormone naturally, unlike exogenous HGH which directly introduces the hormone.
Detailed Explanation
A secretagogue is any substance that causes another substance to be secreted. In the peptide world, the term most commonly refers to growth hormone secretagogues - compounds that stimulate the pituitary gland to produce and release growth hormone. This approach differs fundamentally from exogenous hormone replacement (like HGH injections), which directly introduces the hormone and can suppress natural production. Secretagogues work with the body's own production machinery, maintaining natural feedback loops.
Practical Context
GH secretagogues include two main classes: GHRPs (Ipamorelin, GHRP-2, GHRP-6) which initiate GH pulses, and GHRH analogs (CJC-1295, Sermorelin) which amplify those pulses. By working through natural pathways, secretagogues are considered to have a more favorable safety profile than direct HGH administration. However, they also produce more modest GH elevation. The most effective approach combines both a GHRP and a GHRH analog.
Frequently Asked Questions
Are secretagogues safer than HGH?
Secretagogues are generally considered to have a more favorable safety profile because they work through natural pathways and maintain the body's feedback mechanisms, but they also produce more modest GH elevation.

Related Terms
- GH (Growth Hormone) - A hormone produced by the pituitary gland that stimulates growth, cell reproduction, and regeneration. GH secretagogue peptides stimulate the body's natural GH production.
- GHRP (Growth Hormone Releasing Peptide) - A category of peptides that trigger growth hormone release from the pituitary gland. Examples include Ipamorelin, GHRP-2, and GHRP-6.
- GHRH (Growth Hormone Releasing Hormone) - A category of peptides that amplify growth hormone pulses. Examples include CJC-1295 and Sermorelin. Most effective when combined with a GHRP.
- Pulsatile Release - The natural pattern of GH secretion in which hormones are released in bursts rather than continuously. GH peptide stacks aim to mimic this natural pattern.
