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.
Mechanism of Action
Binds 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.
Dosage Overview
Dose Range
100 mcg – 300 mcg
Route
subcutaneous
Frequency
3x daily
Cycle Length
8–12 weeks
Reconstitution
Typical Dosage (Research)
Typical dosing: 100-300mcg administered 2-3 times daily. Often stacked with GHRH peptides for enhanced GH release.
Subcutaneous injection on an empty stomach. Can be used at bedtime to enhance natural GH pulse during sleep.
Considerations for Men & Women
Women: Similar to GHRP-6 but with somewhat less appetite stimulation. Still raises cortisol and prolactin — monitor if using alongside hormonal birth control or during perimenopause. Higher GH sensitivity in women may mean lower effective doses.
Men: Effective GH secretagogue with moderate appetite increase. Cortisol and prolactin elevation should be monitored, especially in long-term use. Often combined with Mod GRF 1-29.
