What Oxytocin is

Peptide hormone, plain

A nine-amino-acid hormone your body makes, studied at the receptor level.

Famous, and famously over-claimed.

You've probably heard a lot of big stories about this one. We're going to stick to what's actually on the receptor level.

What it is: a lab-made copy of oxytocin, a peptide hormone your body produces on its own. (A peptide is a tiny chain of the building blocks your body uses.)

What it does: researchers study how it binds the oxytocin receptor and signals through that pathway. That's the mechanism, full stop. It lives on the Brain + Mood shelf near Selank.

What it actually does

Oxytocin is a peptide hormone your body already produces. The research interest is mechanism-level: how it binds the oxytocin receptor and how that signal moves.

There are a lot of confident stories about this compound out there. We're not going to repeat them. The receptor pathway is what gets studied, and that's what we'll describe.

A bit more on the mechanism, without the mythology. The hormone is a small nine-amino-acid ring, and the receptor it acts on shows up in several tissues, which is part of why the signaling has been studied from so many angles. Researchers look at how tightly it binds, how quickly the signal fades, and how the receptor behaves when it is activated again and again. Most of that work happens in cell cultures and animal models rather than people, the usual early-research setup. The short version: there is a clean, specific pharmacology here, far more measured than the popular reputation, and that pharmacology is what the lab studies actually describe.

The research so far

Oxytocin is a long-known hormone with a well-mapped receptor. You can read the full chemical profile on its PubChem entry.

The backstory

Oxytocin has been known to science for a very long time.

  1. Long known

    One of the earlier peptide hormones identified.

  2. Receptor mapped

    Its receptor and signaling are well characterized.

  3. Where it stands

    A defined receptor target wrapped in a lot of popular claims. We're not telling you what it does for you, just the pathway studied.

What is Oxytocin?
Oxytocin is a naturally occurring peptide hormone, studied in neuroscience research for how it binds and signals through the oxytocin receptor. Sold as a lyophilized powder for research use only.
What is the molecular weight of Oxytocin?
Oxytocin has a molecular weight of 1007.2 g/mol and the molecular formula C43H66N12O12S2 (PubChem CID 439302).
How is the purity verified?
Every batch is tested by HPLC to at least 99% purity, and the Certificate of Analysis for that batch ships with the order and is shown on the product page.
How should it be stored?
Store the lyophilized powder cold and protected from light. Keep it sealed until use to maintain stability.
Does it come with a COA?
Yes. Every batch ships with its Certificate of Analysis, shown right on the product page, so you can confirm purity before you buy.
What does "research use only" mean?
It means this product is intended strictly for laboratory research. It is not for human or animal consumption, and nothing on this page is a medical or therapeutic claim.
