Health New Zealand distributed more than 2300 peptide-injecting kits through its Needle Exchange Programme over a six-week period following a September 15 rollout, as regulators and medical professionals raise urgent safety warnings about unapproved weight-loss and fitness drugs purchased via social media.
Pharmacies and Needle Exchanges Distribute New Injecting Kits
Health New Zealand supplied peptide-specific injecting kits to around 190 pharmacies and regional needle exchange providers, according to a Health New Zealand media release. Deborah Woodley, Health New Zealand’s director of maternity, child, youth and prevention, stated that the strong uptake reflects significant demand for equipment tailored to peptide injecting. Each kit contains syringes, needles, a returns container, and an information leaflet.
Official figures show a sharp rise in demand for injecting gear. A Ministry of Health briefing obtained by Newstalk ZB under the Official Information Act revealed that 26,731 one-millilitre insulin needles were bought through the programme’s online shop between January and June 2025. During the same six months in 2026, that figure jumped to 141,523.
Medsafe Seizes Hundreds of Illegal Peptide Parcels
Medsafe warned that many online-sourced peptides are illegal, untested, and potentially dangerous. The regulator intercepted more than 370 parcels containing peptides and similar drugs in 2025, compared to 15 in 2022, and seized over 200 parcels in the first four months of 2026 alone. Authorities also contacted 22 New Zealand websites selling the products, resulting in all of them being taken down.
In a consumer advisory issued on 21 May 2026, Medsafe cautioned that unregulated products carry a real risk of poor quality, incorrect labeling, harmful contaminants, and a lack of sterility. Dr Paul Harris of the Harris Peptide Laboratory analyzed imported samples and found that a “Wolverine Stack” mixture failed to contain the advertised TB-500 peptide.
Users Report Easy Online Access
Oceane Ceballos turned to social media to purchase retatrutide, known as “Reta,” after seeing transformation videos online. Ceballos stated that ordering the unapproved weight-loss drug was simple and cost $200 through a “friend of a friend” with a supplier in China.
Health Officials Report Unknown Market Size for Imported Products
Packs can be ordered by participating pharmacies using the same process in place for other programme equipment, and users are instructed to dispose of used equipment in the returns container before dropping it off at their nearest pharmacy or provider. Bronwyn Petrie, Health New Zealand’s group manager of population health, stated that nobody yet knows how big the market is. Dr Paul Harris, who runs the Harris Peptide Laboratory, stated regarding his analysis of imported products: You’d be surprised.
Discussing a sample of a Wolverine Stack,
which is a mixture of two peptides consisting of the Body Protective Compound and TB-500, Dr Harris noted that he couldn’t see any evidence of TB-500 in that sample

Frequently Asked Questions About Unapproved Peptide Injections
Why did Health New Zealand start providing peptide-injecting kits?
Health New Zealand introduced the kits through the Needle Exchange Programme to reduce blood-borne infections and injection-related harm. Officials emphasized that providing sterile equipment does not endorse the use of unapproved medicines.
What dangerous substances have tests found in imported peptides?
Independent laboratory testing by Dr Paul Harris found that a “Wolverine Stack” sample contained no evidence of the claimed TB-500 peptide.
How are buyers typically sourcing these unapproved drugs?
Users report purchasing peptides via bank transfers through community pages and contacts on social media platforms. Suppliers often ship the products directly from overseas sources.
