Frequently asked questions

Is it legal to buy Mounjaro or Wegovy online in the UK?

Yes, from a regulated provider. These are prescription-only medicines, so a legitimate online service must run a clinical consultation and have a UK-registered prescriber approve you before dispensing. The pharmacy itself must be registered with the General Pharmaceutical Council. Anyone selling without a prescriber, or shipping unbranded “peptide” vials, is operating illegally.

How much does Mounjaro cost from an online pharmacy?

Across the 52 national online providers whose standing Mounjaro prices we verified, the lowest starting price is £124.99 a month at the 2.5mg dose (Cured Pharmacy), with a median of £167. Advertised “first month from £69” rates are introductory offers, not the ongoing price, and your cost rises as you titrate up. Checked on 1–2 August 2026.

Are online providers cheaper than a local pharmacy?

Often, but not always. National services compete on price and volume: Mounjaro starts at £124.99 online. A local pharmacy gives you an in-person consultation, someone to ask about injection technique, and no delivery wait. Compare both: each city guide lists local providers too.

How do I check an online pharmacy is genuine?

Look it up on the General Pharmaceutical Council register at pharmacyregulation.org. Every registered pharmacy has a 7-digit premises number and must display it. Registered distance-selling pharmacies also carry the GPhC internet pharmacy logo, which links back to their register entry.

Does Pensday earn commission from these providers?

No. There are no affiliate links, paid placements or referral fees anywhere in these guides, and no provider has paid to appear or to rank. Pensday makes money from its app, not from sending you to a pharmacy.
