GHRP-2

Also cited in the literature as Pralmorelin

A small peptide that triggers growth hormone release. In Japan it was approved as a diagnostic test rather than a treatment.

Regulatory status: Not licensed as a medicine in the United Kingdom. It holds no MHRA marketing authorisation, has no approved indication, and is not approved for human or animal use.

What it is

GHRP-2, also called pralmorelin, is a laboratory-made peptide of six amino acids. It acts at the receptor the natural hunger hormone ghrelin uses.

How researchers think it works

Studies found that it activated the ghrelin receptor in the pituitary gland and hypothalamus, prompting a burst of growth hormone release.

What has research seen in people?

Human studies reported clear short-term rises in growth hormone, which is why Japanese regulators approved it as a diagnostic test rather than a treatment.

No trials showed that repeated use changed body composition, strength or health outcomes.

Researchers also recorded effects on appetite and on cortisol, and flagged those as reasons for caution.

What studies have found

  • Published studies in adults and children reported measurable rises in growth hormone after it was given, and Japanese regulators approved it as a diagnostic test for growth hormone deficiency.
  • Researchers did not publish trials showing that repeated use improved body composition, strength or health outcomes.

What we still do not know

  • The published work measured hormone responses over hours, not long-term effects.
  • Effects on appetite and on the hormone cortisol were also reported, and researchers noted these as reasons for caution.
