They show up in your feed promising a leaner body, faster recovery, or younger skin, shipped straight to your door with no prescription. Health Canada just tested thousands of them and found something nobody ordered: bacteria.
Health Canada is warning Canadians not to buy or inject unauthorized peptides after lab testing found bacteria in products sold online, according to a public advisory issued on November 6. The department seized more than 11,400 vials from Shanghai ERP Peptide Biotechnology Co. Ltd., known as ERP Peptide, and from two Canadian websites that sold its products, truenorthbiolabs.ca and bcaxiompeptide.com, which are no longer active. Testing found Acinetobacter seifertii, Acinetobacter nosocomialis, and Cutibacterium acnes, and CTV News reported that the two Acinetobacter species can cause severe, drug-resistant, and potentially fatal infections, especially in people with weakened immune systems.
Key takeaways
Health Canada seized more than 11,400 peptide vials from ERP Peptide and two Canadian websites, and testing found three types of bacteria.
Two of the bacteria can cause severe, drug-resistant infections, especially in people with weakened immune systems.
The seized products included versions of tirzepatide, retatrutide, tesamorelin, MOTS-C, NAD+, and hCG.
Every authorized drug in Canada carries an eight-digit Drug Identification Number, or DIN, on its label.
If you injected one of these products and notice redness, swelling, pain, fever, or chills, get medical care right away.
Why are weight loss peptides suddenly everywhere?
Peptides are short chains of amino acids, and some are legitimate, widely used medications, including popular weight loss drugs such as Ozempic, Wegovy, and Zepbound. In Canada, injectable peptides are regulated as prescription drugs, meant to be used under the care of a licensed health professional.
The boom in weight loss peptides has built a shadow market alongside the real one. The products seized from ERP Peptide included versions of tirzepatide, the ingredient in an approved weight loss drug, and retatrutide, an experimental drug that is not authorized for sale in Canada. Health Canada says unauthorized products like these have not been assessed for safety, effectiveness, or quality, and selling them is illegal. This is not the first crackdown, either, as our report on an earlier peptide seller Health Canada shut down showed.
What does research use only really mean?
Many of these vials carry a label reading research use only, not for human consumption. Sellers use that phrase to sidestep drug rules, and Health Canada's answer is blunt, since products meant for laboratories are not meant for bodies.
The marketing is often slick, with influencer videos and confident before-and-after claims. Our report on fake doctor videos selling pills that never arrive shows how convincing these online pitches can look, even when nothing about them is real.
What could be inside the vial besides the drug?
The bacteria are the headline, but they are only one risk. Nobody can know how these products were made or what is really inside the vial. Health Canada warns that an unauthorized peptide may contain too much, too little, or none of the active ingredient, along with unlisted ingredients or contaminants such as solvents, heavy metals, particles of glass or plastic, or microbes.
Even a clean vial carries risk when no health professional is involved. Health Canada lists hormonal imbalance, mood swings, blood sugar swings, liver or kidney damage, blood clots, and the growth of cancerous tumours among the possible harms of injecting an unauthorized peptide.
What are the signs of infection after an injection?
Injecting a contaminated product can lead to serious infections, hospitalization, and in severe cases a life-threatening bloodstream infection. The early signs of infection are redness, swelling, or pain at the injection site, a fever, chills, or simply feeling unwell, and Health Canada says to get medical attention right away if any of them appear.
How do you check for a Drug Identification Number?
The simplest protection takes seconds. Every authorized prescription drug in Canada carries an eight-digit Drug Identification Number on its label, and our guide to what your pharmacist wishes you knew covers other ways a pharmacist can help you check what you take.
Look for the DIN. Check the label for an eight-digit Drug Identification Number before you buy any injectable product.
Search the database. Look the product up in Health Canada's Drug Product Database to confirm it is authorized.
Buy from a licensed pharmacy. Only fill prescriptions through a licensed Canadian pharmacy, never a website shipping vials with no prescription.
Stop and dispose safely. If you have one of these products, stop using it and take leftover vials to your local pharmacy for disposal.
Report problems. Report side effects or suspicious products to Health Canada, since those reports help pull dangerous products off the market.
Frequently asked questions
Are peptides legal in Canada?
Authorized peptide drugs, such as approved weight loss medications, are legal with a prescription. Selling unauthorized peptides is illegal, and Health Canada regulates injectable peptides as prescription drugs. Products labelled for research use only are not authorized for people, whatever the seller claims on the website or in ads.
What should I do if I injected an unauthorized peptide?
Stop using it, keep the vial or packaging, and watch for redness, swelling, pain, fever, chills, or feeling unwell. Get medical care right away if any of those appear, and bring the product with you. Take leftover vials to a pharmacy for safe disposal instead of the garbage.
How can I get weight loss medication safely?
Start with a conversation with a family doctor, nurse practitioner, or virtual care provider about whether an authorized option fits your health. Approved weight loss drugs come with a DIN, a prescription, and follow-up, and unauthorized peptides come with none of those safeguards.
