FAQ

Questions, answered

Who can buy from Peptides Only?

Our products are sold only to qualified researchers aged 21 or over, for laboratory research. They are not for human or veterinary use, and we do not provide usage or dosing guidance.

How does Buy One, Get One Free work?

Add any two eligible vials — they can be different products — and the lower-priced one is free. Two of the same product and size are paired first, so two of one vial and two of another get one of each free. Any vials without a match pair up with each other, and the lower-priced one is free. The discount is applied automatically at checkout. Research stacks and supplies are not included.

Where do I find the COA for my vial?

Every peptide vial carries an RFID tag: hold it to the back of your phone and its certificate of analysis opens automatically. Every product page also links to its certificates, the COA library lists them all, and each certificate carries a lot number that matches the label on your vial.

How fast do orders ship?

In-stock orders placed before the daily cutoff are dispatched the same business day. Shipping options and delivery estimates are shown at checkout, and orders over $150 ship free.

How should vials be stored?

Keep lyophilized vials frozen or refrigerated, away from light and moisture. Storage details for each compound are on its product page and certificate.

Can I return an order?

Because of their nature, research compounds cannot be returned once shipped. If an order arrives damaged or incorrect, contact us within 72 hours of delivery and we will make it right.

Do you offer wholesale or lab pricing?

Yes. Institutions and labs ordering in volume can apply for wholesale terms on the wholesale page.
