Shipping & Returns

Orders placed before 2:00 PM (local warehouse time) on business days are dispatched the same day; later orders ship the next business day. Compounds are packed with cold-chain protection appropriate to the product and season. You'll receive a tracking number by email as soon as the label is created.

Domestic shipping is a flat $12, and free on orders over $200. Expedited options, where available, are priced at checkout.

We currently ship within the United States only. We do not ship to P.O. boxes for cold-chain orders, and we cannot ship to jurisdictions where receipt of research compounds is restricted — it is your responsibility to know your local rules.

Lyophilized peptides are stable in transit at ambient temperature for short periods; cold packs are added where needed. On arrival, move products promptly to the storage conditions printed on the label and COA (typically −20°C, protected from light). Products left unclaimed, undeliverable, or held at a carrier facility are outside our control once tracking shows a delivery attempt.

Because we cannot verify the storage and handling of compounds once they leave our facility, opened or temperature-sensitive products cannot be returned or restocked. This protects every researcher who orders from us — no vial we sell has ever left our chain of custody.

Unopened lab supplies (e.g., bacteriostatic water) in original sealed packaging may be returned within 30 days for a refund minus outbound shipping.

If your order arrives damaged, is missing items, or contains the wrong product, contact us within 7 days of delivery with your order number and photos of the packaging and contents. We will replace the affected items or issue a refund — our choice will always favor getting usable material to your bench fastest.

Packages lost in transit (no delivery scan) are replaced or refunded once the carrier confirms loss or tracking has been stalled for 10 business days.

We can modify or cancel an order any time before dispatch — email us as soon as possible with your order number. Once a package ships, changes are no longer possible, and the returns policy above applies.
