How orders travel
Lyophilised peptides are shelf-stable in transit — that is the whole reason they are freeze-dried. Removing the water removes what the material needs in order to degrade, so a few days at ambient temperature does not meaningfully affect it. Orders ship at room temperature, without ice packs, and that is the normal way this material moves.
What matters is what happens after it arrives: put unopened vials in a freezer, and keep anything you reconstitute in the fridge. Storage guidance for each compound is on its product page.
Order tracking
You'll get a confirmation when payment clears and a tracking number when the label is generated. If tracking hasn't moved after two business days, email us — carrier scans are missed more often than parcels are.
Returns
Because these are research materials whose storage conditions can't be verified once they leave our control, we cannot accept returns on opened or unsealed vials. That's a chain-of-custody constraint, not a customer-service one.
- Damaged in transit — photograph the parcel and vials before handling further, and email us within 72 hours of delivery. Replaced at no cost.
- Wrong item shipped — our error, our postage. Full replacement.
- Unopened, sealed, within 14 days — returnable for store credit less return shipping.
- Lost parcels — we file the carrier claim and reship once the claim is opened.
Where we ship
United States only at present, to all 50 states. We do not ship internationally — research-material import rules vary too widely by jurisdiction for us to do it responsibly. We will not mark parcels as gifts, understate declared value, or mislabel contents.
Payment
Checkout is encrypted and we do not store card details on our servers. Orders are not packed until payment clears.
