What if the package or label seems wrong?
Contact the pharmacy that supplied it and the person who prescribed it to check the product before using it.
The Food and Drug Administration, or FDA, is the US medicine agency.
Made to order is what “compounded” means.
As checked in September 2026, the FDA had found fake compounded semaglutide and tirzepatide with false pharmacy details on their labels.
The names Ozempic and Wegovy refer to semaglutide, while Mounjaro and Zepbound refer to tirzepatide; the exact product still needs checking.
Does every peptide need the fridge?
Storage advice checked in September 2026 differs by product: some peptide medicines use room-temperature storage, while others need refrigeration.
Read the exact product’s label and ask the pharmacy to explain its instructions. Avoid guessing from a general peptide page.
GLP-1 is made by your body and helps regulate blood sugar and hunger. GLP-1 medicines copy its action.
For injectable GLP-1 deliveries that are warm or have too little refrigeration, the FDA’s advice checked in September 2026 is: do not use the medicine.
When is the priority urgent help?
An allergic reaction that is severe can threaten life; MedlinePlus advises emergency care for severe symptoms, with trouble swallowing or breathing among the examples.
Seek emergency care for those severe symptoms. Do not wait for a price or refill reply.
Can I report a medicine problem?
Patients can use MedWatch to report problems with medical products to the FDA.
A report documents a concern without proving the medicine caused the problem.
Get help with the immediate problem first. Reporting is a separate step.
