GH Secretagogues
Growth hormone release from the anterior pituitary is governed by two distinct receptor systems. The GHRH receptor responds to growth-hormone-releasing hormone and its analogs; GHS-R1a, the ghrelin receptor, responds to a separate family of secretagogues. Because the two pathways converge on the same somatotroph population through different second-messenger routes, they are frequently studied together rather than in isolation.
They are grouped by the receptor system they act on, not by structure — the two pathways sit together because they converge on the same cells, not because the molecules resemble each other.
Laboratory research use only. Not for human or veterinary use.

Two molecules, two receptors — a GHRH-receptor analog paired with a selective GHS-R1a agonist. The choice when the question is how the two pathways behave together rather than either alone.
