Quick answer
What is Oxytocin?
Built from index records dated 2026-10-09 to 2026-10-13 Compiled by an automated pipeline, checked by The Peptide Observer editorial desk. No qualified clinical reviewer. How this site works
Oxytocin is a peptide, grouped on this site under Endocrine and immune signalling peptides, and the 12 research records kept here are 6 from studies in rats or mice and 6 that do not state what kind of study it is.
The literature search returned 30,040 records. This site keeps 12 of them, which is 0.04 per cent of what came back.
What it is
This site puts it in the Endocrine and immune signalling peptides group.
A posterior pituitary nonapeptide acting at the oxytocin receptor; the retrieved records report central effects on social cognition and fear circuitry.[1, 2]
Stated in the titles of the cited 2001 Physiological Reviews and 2005 Journal of Neuroscience 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; 6 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 30,028 retrieved records say. They are not in this index.
