GHRP-2 (Pralmorelin) is a synthetic hexapeptide ghrelin receptor agonist and one of the most extensively studied growth hormone secretagogues. It produces robust GH pulses with less hunger stimulation than GHRP-6.

How does GHRP-2 compare to GHRP-6?

GHRP-2 produces a stronger GH pulse than GHRP-6 with significantly less appetite stimulation. However, it has more cortisol and prolactin elevation than Ipamorelin.

Can GHRP-2 be stacked with GHRH peptides?

Yes. GHRP-2 + CJC-1295 or Sermorelin is a classic GHRH/GHRP combination producing synergistic GH pulses greater than either compound alone.

What is the difference between GHRP-2 and Ipamorelin?

GHRP-2 produces a stronger GH response but elevates cortisol and prolactin. Ipamorelin is more selective - strong GH release with minimal off-target hormonal effects.

How does GHRP-2 compare with ipamorelin?

GHRP-2 is a stronger GH releaser per dose, but it also produces modest cortisol, ACTH, and prolactin elevation that ipamorelin does not. Ipamorelin is cleaner; GHRP-2 is more potent and has a richer clinical pharmacokinetic dataset. The choice depends on whether your research protocol needs selectivity or potency.

Is the appetite stimulation from GHRP-2 strong?

Moderate. GHRP-2 activates hypothalamic ghrelin receptors enough to produce a noticeable increase in hunger in research subjects, but less dramatically than GHRP-6, which is the strongest orexigenic member of the family.

Can GHRP-2 be dosed orally?

Yes, oral bioactivity has been demonstrated across multiple species, though absolute oral bioavailability is quite low (roughly 0.3%). That means meaningful oral dosing requires much larger amounts than SC or IV, but the route does work in research protocols.

How should GHRP-2 be stored?

Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1-6 °C and protect from light. GHRP-2 is reasonably stable in solution within the standard peptide-handling window.

Pralmorelin // KP-102 // CAS 158861-67-7 // Strong GH-Releasing Peptide

A stronger GH pulse than GHRP-6 with moderate appetite stimulation. Extensively studied second-generation GH-releasing peptide.

GHRP-2 is a 6 amino acid peptide that triggers strong growth hormone release by activating ghrelin receptors in both the pituitary gland and the brain. Compared to GHRP-6, it produces a stronger GH response with less hunger stimulation, though some cortisol and prolactin elevation can occur at higher doses.
