What this means

  • 01

    No product containing Semaglutide with B12 is approved by TGA for any use in Australia. So nothing on sale is allowed for use in people.

  • 02

    "Research use only" is a label sellers put on. It is not a legal category that allows use in people, and it does not get a product out of medicines law.

  • 03

    Importing it, supplying it or promoting it for use in people can fall under medicines law in Australia. This page is general information, not legal advice.

What Semaglutide with B12 is

A pharmacy-made premix where the B12 dose is set by the semaglutide dose, not by anyone's B12 level. The B12 stays at 0.5 mg/mL in every strength, while semaglutide comes at 1 or 5 mg/mL. So one strength gives five times more B12 per milligram of semaglutide than the other. No study has tested the mix. No study backs the reason the B12 is added.

Compounding pharmacies pair semaglutide with B12, in the form called cyanocobalamin. The reasons they give are that B12 helps with the sick feeling and the tiredness people get on a GLP-1 drug.

How it works: Semaglutide copies the gut hormone GLP-1. It slows how fast the stomach empties and turns down appetite, through the brain and the body.

Approval history: Not an approved product. Pharmacy-mixed (compounded) products are not FDA approved. They are not checked for safety, for whether they work, or for quality. The FDA has also raised concerns about unapproved GLP-1 products sold for weight loss.

How TGA treats this kind of product

Registers or lists medicines and health products on the ARTG, its official register. It also sorts substances into schedules in the Poisons Standard. Many peptides are Schedule 4 (prescription only). So having them without a prescription, or importing them for yourself, is restricted. That is true even when no product is registered.

The legal category above is how The Longevity Archive reads Therapeutic Goods Administration listings for Semaglutide with B12 on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.

Semaglutide with B12 in sport and the military

Whether Semaglutide with B12 is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Australia. Before you compete or get tested, look up Semaglutide with B12 by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.

The rules you compete or serve under decide this, not this page.
