GHRP-2 vs Humanin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

GHRP-2

Growth Hormone Releasing Peptide 2 (GHRP-2) is considered one of the most potent GHRPs available. It provides strong GH release with moderate hunger increase compared to GHRP-6.

Side-by-Side Comparison

AspectGHRP-2Humanin
MechanismBinds to the ghrelin receptor (GHS-R) to stimulate GH release from the pituitary. Also has some direct effects on the hypothalamus. Causes less appetite increase than GHRP-6.Binds to IGFBP-3 and BAX, inhibiting apoptosis. Activates STAT3 signaling and enhances cellular survival under stress. Protects mitochondrial function and reduces oxidative stress.
Typical DosageTypical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release.Research protocols vary widely. Studies have used doses from micrograms to milligrams depending on the analog and route. HNG (S14G-Humanin) is a more potent analog.
AdministrationSubcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep.Subcutaneous or intraperitoneal injection in research. Various analogs exist with different potencies and stabilities.
Side EffectsModerate hunger increase, water retention, potential prolactin and cortisol elevation (less than GHRP-6), tingling sensations.Limited human data. Generally well-tolerated in animal studies. May affect glucose metabolism.
