Overview

Oxytocin is a nine-residue peptide hormone whose ring is closed by a disulfide bridge between its two cysteines, leaving a three-residue tail with an amidated C-terminus.

The certificate for one batch of Oxytocin is published in full, covering the 10 mg fill, with its HPLC chromatogram and a laboratory report number that can be independently verified.

The minimum is 50 vials (5 kits) across the whole order, not per compound: this compound is ordered in 10-vial kits and can be mixed with anything else in the catalog to reach it. Bulk orders earn volume pricing on every line.

Wholesale & bulk pricing

PER VIAL · 1 SKU

Prices are per vial and every compound ships in 10-vial kits, so buying Oxytocin in bulk is a matter of kit count. Your tier is set by the compound kits on the order, not per compound — so 25 kits split across several compounds earn the same Tier 2 price on Oxytocin as 25 kits of Oxytocin alone. The minimum is 50 vials (5 kits) across the order, and supplies sit outside both.

Testing & certificate

Every new batch is tested by an independent lab before release — identity, quantity, purity, endotoxins, heavy metals, and sterility. Certificates are batch-specific: the purity number on the certificate is the exact value returned for that batch — nothing is rounded up, nothing is estimated.

Issued by an independent lab. Each certificate carries a report number and access code you can check directly with the lab — we do not stand between you and the laboratory. Certificates are batch-specific, so the figures above belong to the batch named on each row and not to any other.

All Oxytocin certificates of analysis, with chromatograms → Every published certificate is also searchable by batch or report number in the certificate library.

Wholesale terms

MINIMUM ORDER
50-vial minimum. Mix any compounds to reach it. Ordered in 10-vial kits.
PRICING
From $14.00 per vial at 100+ kits — see the tier table. Confirmed in writing with your order.
WHO WE SELL TO
Resellers and institutions (resale certificate welcome)
ORIGIN
US-sourced and US-warehoused. Never relabeled from overseas.
LABELING
Stock vials ship unlabeled. The labeled vial shown on our product pages and catalog is an illustration — it exists so you can see the compound and dose at a glance, and is not a photograph of what arrives. Your lot number is on your invoice, which is how you match what you received to its certificate. Printed vial labels are the white-label program.
SHIPPING
Shipping within the United States is charged per 400 vials: UPS 2nd Day Air $35.00 or UPS Next Day Air $100.00 for each 400 vials or part of 400, so 401–800 vials ships 2nd Day Air for $70.00. You choose the service on the order form. Orders in by noon Pacific ship the same business day from Costa Mesa, California; 2nd Day Air arrives in 1–2 business days — about 1–2 days in California, around 2 nationwide. Special destinations are quoted individually. Cold-chain packaging, where a compound requires it, is quoted and billed separately.
RETURNS
Research peptides are not returnable once shipped: sealed vials and chain-of-custody mean a returned vial cannot be released to another buyer. If a shipment arrives damaged, incomplete, or is not what you ordered, contact the desk and we will make it right.

Frequently asked

What is the minimum wholesale order for Oxytocin?

Is there a certificate of analysis for Oxytocin?

Yes. One published batch covers the 10 mg fill, at 99.451% purity, with its HPLC chromatogram and the lab's report number. Vials ship unlabeled, so the batch number for an order is on its invoice.
