Shipping & Returns
Last updated: October 7, 2026
We ship within the United States only. This page explains how and when orders ship, what to do if something arrives damaged or incorrect, and when refunds are available.
1. Order processing
Orders are processed once we have confirmed your order request by email and received payment. Processing usually takes 1–2 business days (Monday to Friday, excluding U.S. federal holidays). Orders confirmed on weekends or holidays are processed the next business day.
2. Shipping methods and cost
We ship with USPS Priority Mail, which typically arrives within 2–3 business days after shipping. Shipping is a $15 flat rate, and free on orders of $100 or more. Your cart shows the shipping cost before you send your order request.
Lyophilized (freeze-dried) peptides are stable at room temperature during normal transit, and are packed to protect them from breakage and light. Store them as described on our FAQ as soon as they arrive.
We do not currently ship outside the United States, or to P.O. boxes where the carrier does not deliver.
3. Tracking and delivery
We email you a tracking number when your order ships. Delivery estimates come from the carrier and are not guaranteed. We are not responsible for delays caused by the carrier, weather or other events outside our control.
4. Address accuracy
Please double-check your shipping address before you confirm your order. If you notice a mistake, email us right away and we will correct it if the order has not shipped yet. We are not responsible for orders delivered to an incorrect address that was provided to us. If a package is returned to us because of an address error, we can reship it once you pay the additional shipping cost.
5. Lost or stolen packages
Once the carrier marks a package as delivered, responsibility passes to you. If tracking shows no movement for 7 days, or your package shows as delivered but you can't find it, email us and we will open a claim with the carrier and help resolve it.
6. Damaged or incorrect items
If your order arrives damaged, is missing an item, or contains the wrong product, email us within 7 days of delivery with:
- your name and the date of your order;
- clear photos of the affected item(s), the packaging and the shipping label.
After we review your claim, we will send a replacement or issue a refund for the affected item(s), at no extra cost to you.
7. Returns
To protect the integrity and traceability of every product we ship, we cannot accept returns of research compounds once they have left our facility, and we cannot resell or restock returned items. This does not affect your right to a replacement or refund for damaged, missing or incorrect items described in section 6.
8. Cancellations and refunds
- Before shipping: you can cancel an order by emailing us before it ships, and we will refund the full amount paid.
- After shipping: orders can no longer be cancelled once they have shipped.
- If we cancel: if we cannot fill an order, for example because an item is out of stock, we will refund the amount paid for anything we cannot send.
Approved refunds are sent back using the original payment method within 5–7 business days.
