Overview

GHRP-2 (Pralmorelin) is a synthetic hexapeptide growth hormone secretagogue. It stimulates robust release of growth hormone and has been investigated for both diagnostic and therapeutic use. It is one of the more potent GHRPs and produces a strong, rapid GH pulse.

Dosing

100 mcg
Common dose
100–300 mcg
Frequency
1–3× daily
Notes
Commonly stacked with a GHRH analogue such as CJC-1295.

Amino acid sequence

D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2

How it works

GHRP-2 acts as a ghrelin-mimetic, binding the GHSR-1a receptor to stimulate growth hormone release from the pituitary. It can also antagonize somatostatin. Its action is synergistic with GHRH analogues, so it is commonly stacked with CJC-1295 or Sermorelin.

Common research uses

  • Strong growth hormone pulse induction
  • Diagnostic GH stimulation testing
  • Muscle and recovery research
  • Metabolic studies

Considerations

Can transiently elevate cortisol and prolactin in some protocols. Research compound with limited long-term human data. Research use only.
