What the Re: News investigation found, why the risks stack up, and the safe path from here
In May 2026, Re: News journalist Zoe Madden-Smith made a phone call at 12:45pm. By 1:27pm she was standing on a residential Auckland street, in broad daylight, holding a vial of powder sold to her as retatrutide, an experimental weight-loss medicine that is not approved anywhere in the world. It cost $200 and took 42 minutes.
If you have been thinking about weight-loss injections, that story was probably written about people like you. Not because you have done anything wrong, but because the sellers know exactly who they are talking to: people who want to improve their health, have heard the medicines work, and are staring at the price and the process of doing it properly.
This article is about what that investigation actually found, and why the convenient option is the one that keeps getting more dangerous.
What the investigation found
The Re: News story documented a trade that is no longer hidden:
- Sellers market peptides openly on social media, behind disclaimers that the products are for "research purposes only".
- The products on offer included retatrutide, tirzepatide, GHK-Cu, BPC-157 and Melanotan II, sold as powders that buyers are left to mix and inject themselves.
- Medsafe was blunt: any product sold for a therapeutic purpose is a medicine, it is unlawful to sell peptides without authorisation, and a "research purposes only" label does not make a sale legal.
- Since December 2025, many of these peptides have been classified as prescription medicines, which means importing, selling or possessing them without authorisation can breach the Medicines Act 1981.
- Testing by the NZ Drug Foundation was inconclusive. Their checks detected what you would expect with peptides, but could not confirm which peptide was actually in a sample or rule out concerning contaminants.
- With no clinician involved, buyers are asking AI chatbots how to inject. One interviewee described it as "literally like having a doctor in your phone".
Why the risk keeps stacking up
Here is the uncomfortable arithmetic of the black market: every unknown adds to the last one, and none of them cancel out.
You do not know what is in the vial, at what strength, or whether it is sterile. Even the country's drug-checking service could not confirm that. You have had no assessment, so nobody has checked whether these medicines are safe for you specifically, or how they interact with your health conditions and other medicines. There is no follow-up, so early warning signs have nowhere to go. And since December 2025, the law sits on the other side of the transaction too.
The trade itself is growing. The NZ Drug Foundation reports enquiries about peptides every day and tests them every week. The bigger this market gets, the more people inject unknown products with no support, and the more of those stories end badly. That is the direction this road runs.
If cost is the reason you are looking sideways
Then you are exactly who legitimate care needs to serve better, and that is a conversation worth having in the open. The medicine itself is only part of what you are paying for either way; the difference is what comes with it. We have written an honest breakdown of the real costs on both paths: Why cheap peptides are expensive.
If you have already bought or used black-market peptides
No judgement here, and you will not get any from a clinician either. Two practical steps:
- The NZ Drug Foundation offers free, confidential drug checking. The Level lists clinics where you can find out what is actually in a product, legally and anonymously.
- Tell a doctor what you have been taking. It is safe to do, it stays confidential, and it means your care is based on reality. If you feel unwell after injecting anything, call Healthline on 0800 611 116, or 111 in an emergency.
The safe path is real, and it is not complicated
New Zealand has approved weight-loss medicines, prescribed by NZ-registered doctors after a proper assessment and dispensed by NZ pharmacies, with support that continues after the script.
