Tirzepatide in the UK: price, prescription rules and how to get it safely

Tirzepatide is prescription-only in the UK

In the UK, tirzepatide — the medicine licensed as Mounjaro — is classed as a prescription-only medicine. That means a qualified prescriber must assess you before you receive it: your medical history, current medications, and whether it is appropriate for you at all.

Any website that will sell you tirzepatide with no assessment, no prescriber and no questions is operating outside those rules. Beyond the legal issue, you have no assurance of what is in the pen, how it has been stored, or who to call if something goes wrong.

What it costs

Prices vary between providers, but legitimate UK services generally charge per pen rather than per month of vague 'supply'. At Apex Labs, tirzepatide is £100 per pen (20mg per pen), with optional next-day delivery at £5.95. You are not charged at the point of ordering — payment is only requested after the prescriber has approved you.

Be cautious of prices that look dramatically cheaper than the rest of the market. The cost of a genuine, properly stored medicine puts a floor under what a legitimate seller can charge.

How the prescription process works at Apex Labs

• You complete a short medical questionnaire — about three minutes.
• Our prescriber reviews your answers, medications and history, and decides whether tirzepatide is appropriate and at what dose.
• Only after approval does your order move forward, and only then is payment requested — by a secure payment link.
• Your pen is dispatched with tracked delivery; next-day delivery is available for £5.95.

If the prescriber decides tirzepatide is not right for you, you are told that plainly and you pay nothing.

Checks worth making before you buy anywhere

• Is a named, qualified prescriber involved before payment is taken?
• Is the price per pen and the dose per pen stated clearly?
• Is there a real way to contact a human — a call-back or support route — if you have a problem?
• Does the site make medical claims that sound too good, or skip safety information entirely? Both are warning signs.

Common questions

Can I get tirzepatide on the NHS? NHS availability is limited and subject to strict eligibility criteria that are being rolled out gradually; most people obtaining it now do so privately through a prescriber-led service.

Is it the same as Mounjaro? Mounjaro is the UK brand name for tirzepatide — the same molecule. Zepbound is the brand name used for weight management in the United States.

How quickly will I receive it? Once the prescriber approves your order and payment is made, dispatch is tracked, and next-day delivery is available. Approval itself depends on the prescriber's review, not a fixed timer.
