GH Secretagogues Control the Shape and Size of Growth Hormone Pulses in Men

Clinical TrialModerate evidence
The takeaway

Combined GHRP-2 and GHRH precisely controlled the waveform, mass, and timing of GH secretory bursts in healthy men, with hypogonadal state reducing burst mass — testosterone and peptides jointly shape GH pulse quality.

Key finding

GHRP-2/GHRH combination precisely controlled GH secretory burst waveform (amplitude, duration, mass) in healthy men, with short-term hypogonadism redu

What the researchers found

GHRP-2/GHRH combination precisely controlled GH secretory burst waveform (amplitude, duration, mass) in healthy men, with short-term hypogonadism reducing burst mass — demonstrating testosterone and secretagogues jointly regulate GH pulse quality.
