Which Oxytocin vendors publish a COA?
29 of the 34 vendors listing Oxytocin say they publish certificates of analysis (COAs). A COA is the vendor’s own claim and can be copied or re-dated, so we also show independent test ratings (Finnrick) on each vendor page where they exist, and let you filter to “COA claimed” vendors.
Does Oxytocin come in forms other than injectable vials?
We also track sprays listings for Oxytocin. They are priced per mg of active ingredient too, but usually cost more per mg than lyophilized vials. Use the form filter above to compare them.

PubMed lists 15,057 papers on Oxytocin: 1225 randomized controlled trials, 1706 human clinical studies and 6980 animal or lab-only studies, plus 935 registered clinical trials. We grade the evidence base as “Strong”: Several randomized controlled trials in humans, often summarized by meta-analyses. This describes how much research exists, not whether it works.
Is Oxytocin legal and safe to use?
Oxytocin is sold for laboratory research use only. PeptideComps compares prices and does not give medical advice, and we can’t vouch for any product’s quality or legality — check the rules where you live.
