Which vendors sell Oxytocin with independent COA testing?

12 vendors in the Merit Verified directory have independent COA evidence on file for Oxytocin — 38 COAs total. COA coverage and test dates are listed on the Oxytocin page at https://meritverified.org/peptides/oxytocin.

How do I verify the quality of Oxytocin from a vendor?

To verify Oxytocin quality, look for an independent certificate of analysis (COA) from a third-party lab — not a lab the vendor owns or pays directly. The COA should state the tested compound, lot number, purity percentage (identity and concentration), and the lab's name. Cross-reference the lot number against the vendor's current stock. Merit Verified indexes COAs for Oxytocin at https://meritverified.org/peptides/oxytocin so you can compare evidence across vendors before buying.

What is the regulatory status of Oxytocin?

Oxytocin is tracked in the Merit Verified registry. Regulatory status for research peptides in the US has been evolving — the FDA has reclassified a number of peptides out of the 503A compounding ingredient list since 2025. Merit Verified does not provide legal or regulatory advice; check official FDA sources or consult a licensed professional for the current status of Oxytocin in your jurisdiction.

Nootropic / Cognitive

Oxytocin

Also known as: Pitocin (IV obstetric)

Oxytocin is a nine-amino acid peptide hormone (Cys-Tyr-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2, with a disulfide bridge between Cys1 and Cys6) produced in the hypothalamic paraventricular and supraoptic nuclei. The synthetic form (Pitocin) is FDA-approved as IV/IM injection for labor induction/augmentation and postpartum hemorrhage control. Intranasal oxytocin is NOT FDA-approved and is used off-label or in research settings for social/behavioral indications, where evidence is mixed.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.
