Secretagogues studied for GH release, IGF-1, and body composition.
Growth-hormone secretagogues are studied for their ability to stimulate the body’s own pulsatile GH release rather than supplying exogenous hormone. The two principal classes — GHRH analogs and growth-hormone-releasing peptides (GHRPs) — act on distinct receptors and are frequently studied in combination for synergistic effect.
Common endpoints include GH pulse amplitude, downstream IGF-1 elevation, and body-composition changes such as visceral-fat reduction and lean-mass support. Preserving the physiological pulsatility and feedback of the GH axis is a defining research consideration for this class.
