What Is Growth Hormone Secretagogue (GHS)?
A growth hormone secretagogue is a compound that stimulates the pituitary gland to produce and release growth hormone. GHS peptides include GHRP-2, GHRP-6, Ipamorelin, and Hexarelin.
Detailed Explanation
Growth hormone secretagogues are compounds that stimulate endogenous growth hormone release from the anterior pituitary gland through two primary pathways: growth hormone-releasing hormone receptor (GHRHR) activation and ghrelin receptor (GHS-R) activation. GHRH analogs like CJC-1295 and Sermorelin work through the GHRHR pathway, while ghrelin mimetics like GHRP-2, GHRP-6, Ipamorelin, and Hexarelin activate the GHS-R pathway. These pathways are complementary, combining a GHRH analog with a ghrelin mimetic produces amplified GH release greater than either alone. Unlike direct GH administration, secretagogues preserve the pulsatile release pattern of natural growth hormone, maintaining feedback regulation and potentially reducing side effects.

Peptide
A peptide is a short chain of amino acids linked by peptide bonds, typically containing 2 to 50 amino acids. Peptides are smaller than proteins and serve as signaling molecules, hormones, and neurotransmitters in the body.
Half-Life
A peptide's half-life is the time it takes for half of the administered dose to be cleared from the bloodstream. Half-life determines how frequently a peptide needs to be administered.
Bioavailability
Bioavailability is the proportion of an administered peptide that reaches systemic circulation in its active form. Subcutaneous injection typically provides 65-95% bioavailability for peptides.
