Regulatory status
Oxytocin is the active ingredient of prescription-only medicines in many countries. Material sold as a 'research' product is not an approved medicine.
In United States the regulator is the U.S. Food and Drug Administration (FDA). Rules on buying, importing and using this product differ by country. Suppliers list it for laboratory research; nothing here is medical advice.

At a glance · 25 Sept 2026
Oxytocin is a nine-amino-acid hormone made in the hypothalamus and released from the pituitary gland. As a prescription medicine (Pitocin, Syntocinon and generic oxytocin infusions) it is one of the most widely used drugs in obstetrics, given by intravenous drip to induce or strengthen labour and to prevent bleeding after birth. The same peptide is sold online as a nasal spray or research vial on the strength of studies of trust, social behaviour, appetite and autism, most of which were small, and the largest of which were negative. Read the full Oxytocin guide, with the published research and references.
The median listed price per mg across every tracked supplier listing Oxytocin in each currency, recorded daily from validated listings only. Days with too few listings to publish are left out, not estimated. How we validate prices
USD · median per mg US$6.50/mg
We began recording daily market statistics on 25 Sept 2026. A trend appears once there is more than one day of data.

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.
For what Oxytocin is and what published studies have found, see our Oxytocin guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in the US? and see all suppliers serving the US.
How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.
Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.
57 of the suppliers PepFinder tracks list Oxytocin and are based in or ship to the US. The highest rated are Bulk Peptide Supply, New-U Research Compounds, Direct SARMS. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews, with stores based in the US placed before those shipping in from abroad; nobody pays to be included or to rank higher.
Listed prices in USD run from US$1.50/mg to US$273.00/mg, median US$6.39/mg, across 74 listings from 46 suppliers. Compare price per mg rather than price per vial, and only within one currency; a price far below the rest is more often a warning than a bargain.
Suppliers on this page list Oxytocin in 1 mg, Pen Kit, 3 cartridges, 2 cartridges, 2mg vial, 1 cartridge. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.
The FDA treats research peptides sold for human use as unapproved new drugs and has said in 2026 warning letters that research-use-only labels do not change that. Our page on whether peptides are legal in the US sets out the rules with a link to every source. This is general information, not legal advice.
The FDA says it is illegal in most circumstances for individuals to import drugs for personal use, and shipments it considers unapproved drugs can be refused entry. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.
Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for Oxytocin from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list Oxytocin on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
