Agonist at GHS-R1a on pituitary and hypothalamic neurons; strong GH release with comparatively less appetite, cortisol and prolactin than GHRP-6.
Known / used for
No approved use; off-label/research for GH stimulation, body composition, recovery; studied as a GH-secretion diagnostic.
Positives
High peak GH release; less appetite stimulation than GHRP-6; short-acting pulse.
Negatives & risks
Can still raise cortisol/prolactin (dose-dependent); water retention/bloating, fatigue, injection-site reactions; no long-term human data; purity concerns.
What people like most (reported community sentiment - not endorsement)
Potent GH 'kick' with modest hunger vs GHRP-6.
