Compounded and fake GLP-1 products
Made with AI tools and overseen by an Australian GP · Updated 8 November 2026
Cheap “semaglutide” from a website, a salon or a DM is not a bargain. It’s a lucky dip, and some of the prizes are hospital admissions.
Quick answer: Australia banned compounded GLP-1 copies from 1 October 2024 because they aren’t checked by the TGA for safety, quality or strength. Fake Ozempic pens bought online have reached Australia, and the US FDA has hundreds of harm reports linked to compounded versions. Get these medicines only on prescription from a registered pharmacy.
Australia
- Compounding banned from 1 October 2024. At the time, at least 20,000 Australians were injecting compounded replicas of Ozempic or Mounjaro, mostly for weight loss.
- The reasons: compounded copies aren’t evaluated by the TGA for safety, quality or effectiveness, and there were reports of harm, including a hospitalisation in Australia.
- Fake Ozempic pens: in October 2024 the TGA warned about counterfeit pens bought from an overseas website. They appeared to be relabelled insulin pens, which can cause dangerously low blood sugar, and one person had life-threatening complications.
- Warning signs of a fake: spelling errors, a leaflet not in English, unsealed or poor-quality packaging, a different cap colour or shape, and labels that don’t stick properly.
United States
- The FDA doesn’t review compounded medicines for safety, effectiveness or quality before they’re sold.
- Dosing errors with compounded semaglutide have led to hospitalisations.
- By 31 May 2026 the FDA had received 990 adverse event reports for compounded semaglutide and more than 730 for compounded tirzepatide, and thinks these are under-reported.
- Products labelled “for research use” or “not for human consumption” are being sold to people. Don’t buy them.
- Semaglutide sodium and semaglutide acetate are different ingredients from the one in approved products.
United Kingdom
- The MHRA warns against buying from beauty salons or social media and has reports of severe side effects from fake GLP-1 medicines.
Staying safe
- Get a prescription from a doctor and have it dispensed by a registered pharmacy.
- Avoid “no prescription needed” websites and peptide sellers.
- Think you have a fake? Stop using it, keep it (it may be tested), see your doctor and report it to the TGA.
Get urgent help (000 in Australia, or your local emergency number) if you feel shaky, sweaty, confused or drowsy after injecting a product from an unofficial source: it could be low blood sugar. Severe vomiting or tummy pain also needs urgent care.

Common questions
Is compounded semaglutide legal in Australia?
No. Compounding GLP-1 medicines has been banned in Australia since 1 October 2024. Only TGA-approved products dispensed on prescription are legal.
Is compounded semaglutide the same as Ozempic?
No. Compounded products aren’t checked by the TGA or FDA for strength, purity or safety, and some use different salt forms of semaglutide from the approved medicine.
How can I tell if my Ozempic pen is fake?
Warning signs include spelling errors, a leaflet not in English, unsealed or poor packaging, a different cap colour and labels that don’t stick. Buy only from an Australian pharmacy and ask your pharmacist if unsure.
What should I do if I’ve used a fake or compounded product?
Stop using it, keep the product, and see your doctor. Report it to the TGA. Get urgent help for shakiness, confusion or drowsiness, which could be low blood sugar.
Are “research peptides” safe to inject?
No. Products labelled for research or not for human consumption aren’t made or checked for people, and the FDA warns against buying them.
