BE CAREFUL WHERE YOU BUY WEIGHT-LOSS MEDICATION
There’s a worrying side to the growth in medicated weight loss that we need to talk about.
I’m increasingly hearing about people buying injections and so-called “research peptides” through social media, private groups, gyms and unofficial sellers.
One name you may have heard is “Reta” or retatrutide.
Retatrutide is currently being studied as a potential weight-loss medication.
But here’s the important part:
It is not currently authorised as a medicine in the UK.
That means you cannot legitimately obtain retatrutide for weight loss from a UK-registered pharmacy.
If you buy a vial online labelled “retatrutide” from an unofficial source, you cannot reliably know:
• what is actually in it
• whether the dose is accurate
• whether it has been manufactured or stored safely
• whether it is sterile
• or what else it may contain
And this isn’t simply a theoretical concern.
The UK medicines regulator has already seized thousands of doses of illegally supplied weight-loss medicines and unlicensed peptides.
There is nothing wrong with considering medicated weight loss.
But where your medication comes from matters enormously.
Prescription weight-loss medication should come through an appropriate prescriber and a registered pharmacy NOT through a WhatsApp contact, Telegram group, gym acquaintance or unofficial online seller.
Weight loss matters. Your safety matters more.
If you are considering medicated weight loss, make sure you know exactly what you are taking, who prescribed it and where it came from.
