GHRP-2 Acetate
Ghrelin receptor agonist (GHS-R1a)
A growth hormone releasing peptide studied for strong GH pulse generation with moderate appetite effect.
How it works
Activates the GHS-R1a receptor in the pituitary and hypothalamus, releasing GH while suppressing somatostatin tone.
What research has shown
Studies report GH increases several fold above baseline, with smaller cortisol and prolactin elevation than GHRP-6 at comparable doses.
Reported ranges in the literature
Low end
100 mcg per administration
Optimal
100 to 200 mcg, one to three times daily
High end
300 mcg per administration
Frequency reported in the literature: One to three times daily
Protocol duration and pairing
Typical study duration
8 to 12 weeks, usually cycled.
Best paired with
Stronger GH release than GHRP-6 with less appetite signaling.
