GHRP-2 Research Hub — GH Release & Ghrelin Receptor Studies
GHRP-2 is a synthetic ghrelin-receptor agonist studied for its dose-dependent stimulation of endogenous GH release. This hub compiles Ares Research's GHRP-2 reference material and comparative literature across the GHRP family.

- Ghrelin / GHS-R1a receptor agonism
- Dose-dependent GH release and ACTH/cortisol cross-reactivity
- Comparisons to GHRP-6, hexarelin and ipamorelin
- Synergy with GHRH analogues (CJC-1295, sermorelin, tesamorelin)

GHRP-2 research articles
All research →GHRP-2 Benefits and Side Effects: A Research Guide
Published benefits, side effects, and class comparisons for GHRP-2 (pralmorelin) — the clinically validated GH-secretagogue used in diagnostic pituitary-reserve testing and GHRP-class research.
Read article →GHRP-6 Benefits and Side Effects: A Research Guide
Published benefits, side effects, and class comparisons for GHRP-6 — the original ghrelin-mimetic GH secretagogue and foundational reference compound for appetite, cachexia, and GH-pulse research.
Read article →Hexarelin Benefits and Side Effects: A Research Guide
Published benefits, side effects, and class comparisons for Hexarelin — the high-potency GHRP with dual pituitary GHS-R1a and cardiac CD36 activity that defines its place in growth-hormone secretagogue research.
Read article →Ipamorelin Benefits and Side Effects: A Research Guide
Published benefits, side effects, and GHRP comparisons for ipamorelin — the most receptor-selective GHRP and standard partner for GHRH analogues.

Researchers studying GHRP-2 commonly cross-reference these compounds.
CJC-1295 is a tetrasubstituted GHRH(1-29) analog studied in two forms: with a drug-affinity complex (DAC) that binds serum albumin and extends half-life to days, and without DAC (also called Mod GRF 1-29) for short, pulsatile GH stimulation.
Explore hub →Ipamorelin is a pentapeptide growth hormone secretagogue and selective agonist of the ghrelin (GHS-R1a) receptor. It is the most receptor-selective GHRP in the published research, notable for stimulating GH release without significantly elevating cortisol, prolactin or aldosterone.
Explore hub →Hexarelin is a synthetic GH-releasing hexapeptide widely cited in growth-hormone secretagogue and cardiac research models. This hub aggregates Ares Research's reference material on Hexarelin mechanism, dosing literature, and head-to-head comparisons with other GHRPs.
Explore hub →GHRP-2 research FAQ
- What is GHRP-2?
- GHRP-2 is a synthetic hexapeptide ghrelin-receptor agonist studied as a GH secretagogue in published research.
- How does GHRP-2 differ from GHRP-6?
- GHRP-2 produces a stronger GH response with less appetite stimulation than GHRP-6, which carries more pronounced ghrelin-like orexigenic effects.
- How is GHRP-2 paired with GHRH analogues in research?
- Combined GHRH + GHRP studies (e.g. CJC-1295 + GHRP-2) consistently report synergistic GH release exceeding either compound alone.
