Cold-chain shipping: how your GLP-1 actually gets to you

All GLP-1 receptor agonists — brand-name and compounded — are required to be stored refrigerated, typically at 36–46°F (2–8°C). The labeling for Wegovy, Zepbound, Ozempic, and Mounjaro all specify refrigeration as the standard storage condition, with limited windows of room-temperature exposure permitted (typically 21 or 28 days at room temperature, depending on product, before discarding).

Compounded preparations should follow the same storage parameters; the active ingredient's stability profile is similar.

Shipments are packed in insulated containers with refrigerated gel packs (sometimes phase-change material) calibrated to maintain the 36–46°F window for the documented transit time — typically 24–72 hours. Reputable pharmacy partners include a temperature indicator strip or QR-coded temperature log inside the package, allowing you to verify that the cold chain was maintained in transit.

Shipping is typically scheduled for early-week delivery to avoid weekend warehouse holds. Most programs require a signature on delivery to prevent doorstep heat exposure.

If your package arrives with a clearly broken cold chain — gel packs fully thawed and warm, the temperature indicator showing excursion, or the medication itself notably warm — do not inject. Contact the pharmacy or telehealth provider immediately to request a replacement.

Reputable providers will replace mishandled shipments at no charge and route the next shipment via expedited delivery. The replacement policy is worth confirming at intake.

Once received, store in your refrigerator — not the freezer. Freezing destroys peptide drugs. The vegetable or middle shelf is typically ideal; door storage is acceptable but exposes the medication to more temperature swings.

If you need to travel with your medication, insulated cooler bags with frozen gel packs maintain temperature for 12–24 hours. For longer travel, request a written letter from your prescribing clinician documenting the medical necessity of refrigerated medication — useful at airport security and at some border crossings.
