Shipping is often the least examined part of an order, right up until a package is delayed or arrives improperly packed. Understanding what "normal" looks like for domestic fulfilment helps you know when to simply wait, and when to contact support.
Processing time vs. transit time
Processing time is how long an order sits before it's packed and handed to a courier; transit time is how long the courier takes to deliver it. A supplier who quotes "under 7 days" is usually describing the combined total — worth confirming, since the two numbers are sometimes advertised separately and can be misread as additive.
Domestic vs. cross-border fulfilment
Orders fulfilled from a domestic warehouse avoid customs processing, which is typically the single biggest source of unpredictable delay in international shipping. If a supplier advertises domestic fulfilment, that's a meaningful reliability signal worth weighing against suppliers who ship cross-border.
Tracking and communication
A tracking number that updates promptly after dispatch is a basic expectation. If tracking shows no movement for several days, that's a reasonable point to reach out to support rather than assuming the worst — carrier scanning gaps are common and don't always indicate a lost package.
Packaging for temperature-sensitive items
Peptides that require cold-chain handling should be packed with appropriate insulation, and in warmer months, ice packs or gel packs. If an item's listing specifies refrigerated storage but arrives in unpadded, uninsulated packaging, that discrepancy is worth documenting and raising with the supplier.
What to do if something goes wrong
Photograph packaging on arrival, especially for anything visibly damaged or improperly insulated. Suppliers with a genuine replacement or refund policy will typically ask for exactly this kind of documentation, so having it ready speeds up resolution.
