Semaglutide mixing chart at 10 mg: what the search is really asking

Why a semaglutide "mixing chart" exists online, and why it doesn't apply here

The mixing-chart concept comes from the United States, where compounded semaglutide vials were widely sold during a period of shortage. Those products are powders or liquids requiring dilution before injection, so patients there needed charts telling them how many units to draw up for a given dose in milligrams. Some charts circulated showing doses of 5 mg, 10 mg, even higher, reflecting the concentrations used in compounded preparations.

None of that applies to UK-licensed treatment. In the UK, Wegovy is supplied as a pre-filled, pre-set injection pen. You dial to your prescribed dose (or, with newer auto-dose pens, there's no dial at all) and press the button. The MHRA has not authorised any compounded semaglutide product for weight management in this country, and UK pharmacies operating within the law do not dispense them. So if a chart you found online lists 10 mg as a step, it was written for a different regulatory context entirely.

That's worth saying plainly, because a lot of people assume the licensed and unlicensed versions are interchangeable. They are not. Purity, concentration, sterility and stability all differ between a manufacturer-produced pen and a vial mixed from bulk powder, and if you want to understand what mixing 5 mg semaglutide actually involves, that context makes clear why it sits outside the licensed UK pathway entirely. The MHRA's warnings about counterfeit and unlicensed weight-loss products are directly relevant here, fake or unregulated semaglutide preparations have been seized in significant quantities across the UK. You can report suspect sellers at the Yellow Card scheme.

What the licensed semaglutide dose schedule actually looks like

For context, the Wegovy injection schedule starts at 0.25 mg weekly, steps through 0.5 mg, 1.0 mg and 1.7 mg, and reaches 2.4 mg as the standard maintenance dose, with a newer 7.2 mg option now approved by the MHRA. The full Wegovy dose range is described in more detail if you want the progression laid out clearly. The Wegovy tablet, approved in the UK in June 2026, follows a separate oral schedule from 1.5 mg up to 25 mg daily. Neither schedule contains a 10 mg step.

A prescriber adjusts your dose roughly every four weeks, with each increase contingent on how you're tolerating the current one. GI side effects (nausea, loose stools, indigestion) tend to be most pronounced after a dose increase and often ease within a week or two. If they don't, staying at the current dose longer is often the right call. That decision belongs to your prescriber, informed by how you're feeling, not to a chart. The NHS semaglutide medicines page covers what to expect at each stage in patient-friendly language.

If you're trying to work out whether 10 mg of semaglutide would represent a meaningful dose increase over what you're currently on, the honest answer is that the comparison doesn't translate across licensing contexts. A 10 mg figure from a compounded vial chart reflects a different concentration and delivery method. Comparing it to a Wegovy pen dose is like comparing tablespoons to millilitres without knowing the density of what's in the spoon.

The clinical decision this query is usually really about

Most people searching for a mixing chart at a specific dose are trying to answer one of two practical questions: am I on the right dose, or could a higher dose produce better results? Those are reasonable questions. They're just better addressed through a prescriber than through a dosing chart.

If you're already on Wegovy through a licensed provider, the right route is a clinical review. If you're thinking about starting semaglutide for weight management, your eligibility depends on your BMI and any weight-related health conditions, the background on what 10 mg means in a semaglutide context may help clarify what you've read elsewhere. For a broader look at how doses compare across the licensed schedule, our semaglutide dose chart puts the progression in one place.

Cost is a reasonable concern too, and understanding what a private prescription actually includes (beyond the pen) matters. Our Wegovy cost overview sets out what the price should cover and what to watch for if a quote looks unusually low. One transparent price that includes clinical review, delivery and ongoing prescriber support is the standard any regulated pharmacy should meet. At nume, a real clinician reviews your consultation the same day, not software, not a queue.
