Category hub · GHRH & ghrelin-receptor class
Growth hormone secretagogue peptides
Growth hormone secretagogues fall into two mechanistic families. GHRH analogues bind the growth-hormone-releasing-hormone receptor on somatotrophs; ghrelin-receptor agonists act at GHS-R1a. Combining one from each family is the classic laboratory design, because the two pathways amplify each other rather than compete.
About this category
What researchers select for here is pulse shape, not potency alone. Short-acting secretagogues produce a sharp, physiological pulse; modified analogues with a longer plasma residence flatten that curve. Selectivity matters too — some older compounds also stimulate cortisol and prolactin, which confounds readouts in endocrine models.
All secretagogue kits ship lyophilised with a lot-specific certificate of analysis. Purity is reported as HPLC main-peak percentage and cross-checked against the expected molecular weight by mass spectrometry.

Frequently asked questions
Why are GHRH analogues and ghrelin agonists studied together?
They act on separate receptors on the same cell population, so in published models the combined signal produces a larger release than either compound alone.
Which secretagogues are considered selective?
Selectivity means little or no measurable cortisol or prolactin response in the reference literature. Each product page states what has been reported for that compound.
What diluent is used for these peptides?
Bacteriostatic water, supplied as 10 ml × 10 sterile liquid vials. Volume per vial depends on the concentration your protocol calls for — our reconstitution calculator works it out.
