Hexarelin Acetate
Well StudiedSynthetic hexapeptide
Hexarelin is a synthetic hexapeptide that acts as a potent growth hormone secretagogue. It has been studied in endocrinology research for its effects on ghrelin receptor activation and growth hormone release. Published research has investigated its binding affinity, potency, and effects on pituitary function. RaysunPeptide supplies Hexarelin Acetate for qualified research and laboratory applications.
Mechanism of Action
Hexarelin binds to the growth hormone secretagogue receptor 1a (GHS-R1a) in the brain and pituitary gland. This binding initiates a signaling cascade that stimulates somatotroph cells in the anterior pituitary to produce and release growth hormone. Hexarelin also has slight, dose-dependent effects on prolactin, ACTH, and cortisol release. Its cardioprotective effects are mediated through CD36 receptor activation and modulation of calcium channels in cardiomyocytes.

| GH optimization | 100 mcg | 2-3x daily | SubQ or IM |
| Enhanced results | 200 mcg | 2-3x daily | SubQ or IM |
| With GHRH (synergy) | 100 mcg each | 2-3x daily | SubQ (combined) |
| Cardioprotection | 100-200 mcg | 1-2x daily | SubQ |
Research Indications
Growth Hormone Enhancement
Most potent GHRP for stimulating endogenous growth hormone release from the pituitary.
Produces synergistic GH release when combined with GHRH, greater than sum of individual effects.
Significant increases in IGF-1 levels through enhanced GH secretion.
Cardiovascular
Protective effects on cardiac tissue mediated through CD36 receptor activation.
Reduces apoptosis of cardiomyocytes and controls cardiac action potential.
Cardiotropic effects mediated by elevation of Ca2+ influx through voltage-gated calcium channels.
Metabolic
Beneficial effects on lipid metabolism via CD36 receptor in non-obese insulin-resistant models.
Improved lean mass to fat ratio through GH and IGF-1 elevation.
Peptide Interactions
Powerful synergy; combination produces GH response greater than sum of individual effects.
Research confirms synergistic GH release when co-administered.
Similar mechanism; typically not stacked together but can be alternated.
Same receptor target; Hexarelin is more potent with less appetite stimulation.
Both are GHRPs; Hexarelin is more potent but may have more side effects.
