Quick answer
What is GHRP-2?
Built from index records dated 2026-10-09 to 2026-10-13 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk How this site works
GHRP-2 is a peptide, grouped on this site under Growth hormone secretagogues, and the 12 research records kept here are 5 from studies in rats or mice and 7 that do not state what kind of study it is.
The literature search returned 212 records. This site keeps 12 of them, which is 5.7 per cent of what came back.
What it is
This site puts it in the Growth hormone secretagogues group.
A synthetic growth hormone-releasing peptide described in the retrieved records as a ghrelin receptor agonist, with reported effects on growth hormone secretion and intracellular cyclic AMP.[1, 2]
Stated in the titles of the cited 2005 American Journal of Physiology and 1996 Journal of Endocrinology papers.
What kind of records
The records kept here are animal and laboratory studies only.
That sentence is produced by counting, not by reading. What was counted: no interventional human trial record; 5 rodent and 0 in vitro records among 12.
What this does not settle
- What it does in a body. Counting records is not reading them, and nothing here has been read in full.
- Whether it causes harm. No adverse-effect row was taken from any source for this entry.
- How long it lasts. No pharmacokinetics source was retrieved for this entry.
- What the other 200 retrieved records say. They are not in this index.
