In letters to peptide sellers, the FDA has warned that injected products can do serious damage. They go directly into the body, sometimes straight into the blood, and skip key defences against poisons and germs such as bacteria, which can lead to life-threatening illness.
The product questions that matter
The main questions are about the exact product, who prepared it, how it arrived and what help is available if something goes wrong.
Why injections need a closer look
A shot goes straight into the body, past the skin and other defences that normally keep germs out. So who made it, and how, matters more than for a pill.
FDA says poor compounding can lead to contamination, or to a dose carrying more or less active ingredient than the label states.
Check the product in front of you
General advice about “all peptides” is too broad. Use the label and the dispensing pharmacy’s instructions for the exact item.
Storage rules differ by product: some approved peptide medicines use room-temperature storage, while semaglutide injection is kept cold before use under its product instructions.
FDA says some fraudulent compounded semaglutide and tirzepatide labels list pharmacies that are fake or that never made the product.
GLP-1 injections are the family of weight and diabetes shots that includes semaglutide and tirzepatide. FDA has received complaints about these refrigerated shots arriving warm or without enough ice packs. It says not to use one that arrives that way, because heat can harm the medicine’s quality.
- Match the pharmacy name on the label to the Ohio licence record.
- Read the storage words for the exact product.
- Ask the dispensing pharmacy what to do about a warm, damaged or unclear shipment.
- Keep a path to the prescribing clinician for questions and follow-up.
When the question is urgent
A guide cannot assess a reaction. Emergency signs need emergency help.
Serious allergic reactions may start seconds or minutes after a dose. If breathing gets hard, the face or tongue swells, you faint or other severe symptoms appear, phone 911 or head to the closest emergency department.
Patients can tell the FDA about a problem with a medicine themselves. The FDA’s free reporting program for this is called MedWatch, and it is open to patients as well as health workers.
Reporting does not replace calling your prescriber or pharmacist about the problem.
