Shipping & returns

1. Processing and transit

Orders placed before 14:00 ET on business days ship the same or next business day. Domestic transit typically runs 2–5 business days. A tracking number is attached to your order as soon as the label is created, and your account's order status moves from paid to shipped to delivered as it progresses.

2. Cold-chain and packaging

Lyophilized peptides are stable at ambient temperature for transit windows; we pack in insulated mailers in hot months. For extended transit protection, the Voyager case and gel packs are available under Gear. Store lyophilized vials refrigerated on arrival and reconstituted solutions per your laboratory's SOPs.

3. Refunds and replacements

Unopened products in original sealed packaging may be returned within 30 days for a refund of the product price. Products that arrive damaged, or that fail to match their certificate of analysis, are replaced or refunded in full — email us with your order number and lot number within 7 days of delivery.

Because our products are laboratory materials, we cannot accept returns of opened or unsealed vials. Shipping fees are refunded only when the return is due to our error.

4. Lost or stuck packages

If tracking stalls for more than 5 business days, contact us and we'll open a carrier investigation; packages confirmed lost are reshipped or refunded. Address errors made at checkout can be corrected until the label is printed.
