Warm arrivals cluster in the hottest months, and most programs put the judgement call on the patient.
Tirzepatide ships refrigerated and must not freeze. Complaints about warm arrivals cluster in summer, particularly on routes with weekend depot time and in southern states.
The failure is usually logistical rather than pharmaceutical: a Friday dispatch, a hot porch, a parcel left at a workplace front desk. None of that is visible in a price comparison.
If a shipment arrives with a warm coolant pack, do not inject and do not decide for yourself that it is probably fine. Photograph the packaging, contact the pharmacy, and ask for a documented stability assessment and replacement.
Ask before enrolling what a programme does when a shipment arrives warm and who pays for the replacement. Programs with a good answer have thought about it; the others will improvise at your expense.
