Shipping policy

Domestic shipping

Free shipping on all domestic orders over $500. Orders below that ship at flat-rate carrier cost — calculated at checkout.

Orders typically ship within 1–2 business days of payment confirmation. You'll receive tracking information by email as soon as the label is generated.

Cold-chain compounds ship with insulation and gel packs where stability requires it.

International shipping

We ship internationally to a limited list of destinations. Import laws governing research chemicals vary by country, and it is the buyer's responsibility to confirm that the compounds they order may be lawfully imported into their jurisdiction. Customs duties and taxes are the buyer's responsibility.

Lost or delayed shipments

If tracking shows your shipment hasn't moved for more than 5 business days, email us and we'll open a carrier trace. We will replace shipments confirmed lost in transit at no additional cost.

Storage on arrival

Most lyophilized peptides are stable at room temperature for short periods after delivery but should be transferred to refrigerator (2–8°C) or freezer (−20°C) storage as soon as practical. Specific storage guidance is included with each shipment and on the COA.
