How to tell a legitimate online health service from a black-market seller

Seven checks that separate a real medical service from a seller with a website, and the red flags that end the conversation

Getting healthcare online is normal now. That is mostly good news: it has made doctors accessible to people who could never fit the waiting room into their lives. But it has also given cover to something else, because on a phone screen, a seller with a slick website and a "research purposes only" disclaimer can look a lot like a clinic.

The good news is that you do not need to be a lawyer or a doctor to tell them apart. The two kinds of operation are built differently all the way down, and about ten minutes of checking exposes the difference every time. Run these seven checks before you hand over money or personal information, and you remove most of the risk in one sitting.

1. You can find out who the doctors are, and look them up

Every doctor practising in New Zealand is listed on the Medical Council of New Zealand's public register of doctors. A legitimate service will tell you who its clinicians are, and their names will check out on the register. Nurse prescribers and pharmacists have public registers too.

A black-market seller has no names to give you. If you cannot find out which registered clinician is responsible for your care, there is no clinician responsible for your care.

2. There is a real assessment, and you can be declined

A legitimate service asks about your health before it offers you anything: your history, your medicines, your blood pressure, the things that decide whether a treatment is safe for you. Crucially, the answer can be no. Being declined is not a failure of the service; it is the proof that a doctor, not a sales funnel, is making the decision.

If approval is guaranteed, instant, or based on nothing but your willingness to pay, you are not being assessed. You are being processed.

3. The medicine is approved, and a pharmacy dispenses it

In New Zealand, prescription medicines are dispensed by licensed pharmacies, in original manufacturer packaging, with a label that carries your name, the prescriber and instructions. That chain, from licensed manufacturer to Medsafe approval to pharmacy shelf to you, is what guarantees the vial contains what it says at the strength it says.

Powder in an unmarked vial, couriered from a stranger, has none of that behind it. When the NZ Drug Foundation tested black-market peptides in 2026, it could not confirm what they contained. If the product does not come through a pharmacy, nobody on earth can tell you what you are injecting.

Red flags that end the conversation

Any one of these is enough:

• First contact or sales through social media direct messages
• No named, registered clinician anywhere
• No health questions before an offer of supply, or approval promised to everyone
• Products described as peptides, research compounds or blends rather than approved medicines
• Vials of powder you must mix yourself
• Payment to a personal bank account, or in cryptocurrency
• Prices dramatically below what the medicine costs at a pharmacy
• Injection or dosing coaching offered by chat or chatbot instead of a prescriber

Ten minutes well spent

Here is the relief on the other side of this checklist: once a service passes it, you can stop carrying the doubt. The background worry about what is really in the vial, what happens if something goes wrong, and who you would even call, all of that lifts, because the answers exist and you have seen them.
