Research
Studies & key findings
- GHRP-2 (pralmorelin/KP-102) is approximately 10-fold more potent than GHRP-6 in stimulating GH secretion, with pharmacological studies (Doi et al., 2004) demonstrating superior resistance to somatostatin suppression compared to GHRH — allowing robust GH release even in states of elevated somatostatin tone.
- In a controlled study in healthy men (Laferrère et al., JCEM 2005), subcutaneous GHRP-2 infusion increased food intake by 35.9% above saline control, confirming its orexigenic activity via ghrelin receptor activation — a property that distinguishes it from more selective GH secretagogues and relevant for cachexia applications.
