Oxytocin: The First Peptide Hormone Sequenced and the Research Record That Followed
Vincent du Vigneaud sequenced oxytocin in 1953 and won the Nobel Prize for it two years later. Seventy years on, oxytocin is one of the most-studied peptides in neuroscience and one of the most over-claimed in popular science writing.
Frequently asked questions
The questions researchers ask before ordering — with straight answers
How do I get a Certificate of Analysis (COA)?
Where we hold a third-party COA for a product, it is linked on the product page as a downloadable PDF. For products marked COA pending, previous lots, or custom documentation needs, submit a support ticket with the lot number and we'll provide the documentation within one business day.
What is the recommended storage temperature?
Unreconstituted peptides: store at -20°C for long-term (up to 24 months) or 2–8°C for short-term (up to 3 months). Reconstituted peptides: always store at 2–8°C and use within 30 days. Avoid repeated freeze-thaw cycles as this degrades the peptide.
What shipping methods are available?
Standard shipping (3–5 business days after dispatch) is a flat $9.99 and free on orders of $200 or more. Orders placed before 12:00 PM Eastern on a business day typically ship the same day from our Jessup, PA facility. Need it faster? Email support@22exo.com before ordering and we can quote express service.
What payment methods do you accept?
We accept cryptocurrency (Bitcoin, Ethereum, USDT, USDC and other major coins, processed by NOWPayments) and Zelle. ACH eCheck bank payments (processed by Green.money) are offered when they appear at checkout. The methods currently available are always the ones shown at checkout. We do not accept credit or debit cards, and we never store bank account numbers.
How do I reconstitute lyophilized peptides?
Use bacteriostatic water (BAC water) for reconstitution. Draw the appropriate volume into a syringe and inject slowly down the inside wall of the vial. Do not spray directly onto the lyophilized powder. Gently swirl until completely dissolved — never shake. Specific volumes are listed on each product page.
Are your peptides for human use?
All 22EXO products are sold exclusively for research and laboratory use. They are not intended for human or veterinary use, nor for food or cosmetic applications. Researchers are responsible for compliance with applicable regulations.
What is your return and refund policy?
Unopened products in their original sealed packaging may be returned within 14 days of delivery for store credit. If a product arrives damaged or does not match your order, contact us right away (within 48 hours of delivery for damage, 7 days for a wrong item) and we will make it right with a replacement, store credit or refund. Opened or reconstituted vials cannot be returned. See our Refund & Returns Policy for the full terms.
Do you offer wholesale pricing?
Yes. Qualified research institutions, laboratories, and resellers can apply for wholesale accounts with tiered pricing. Visit the Wholesale portal to register. Approval typically takes 1–2 business days after tax ID verification.
