What does GHRP-2 do? Benefits and evidence

A peptide that releases growth hormone and can increase hunger.

Also called: Pralmorelin, KP-102, GPA-748.

Growth hormone secretagogues (ghrelin receptor) · Ghrelin receptor agonist and growth hormone secretagogue.

GHRP-2 raises growth hormone and can increase hunger. Japan uses pralmorelin for supervised GH testing. Human studies mostly measured hormone responses, not lasting muscle or recovery benefits. Cortisol, prolactin and blood sugar can change. Long-term wellness use and online product quality remain poorly studied.

  • In small controlled studies, it increased hunger and how much people ate. (Studied in a trial)
  • In a study of adults, a supervised one-time IV test helped tell severe growth hormone deficiency apart from normal. (Studied in a trial)
  • In a small clinic study, a mix including it raised IGF-1, but muscle gain and fat loss were not measured well. (Studied in a trial)

Uses in the sources

  • Studied for GH stimulation testing; pralmorelin has a Japanese diagnostic approval, not an FDA/EMA dose label. (Studied in a trial) (source)
  • SC infusion increased food intake in small, controlled studies of lean and obese adults. (Studied in a trial) (source)
  • A clinician-published combination raised IGF-1; muscle gain and fat loss were not measured adequately. (Clinician-published) (source)
