About GLP Index

GLP Index is a UK price index for prescription weight loss treatment.

GLP Index launched

1 October 2026

What GLP Index does

We publish the delivered price you pay at each pharmacy, for every dose, with the lowest, median and highest figure. We rank pharmacies by price at each dose. We add up the cost of 3, 6 and 12 months. We keep discount codes on separate pages.

What GLP Index does not do

We do not prescribe, sell or supply medicine. We do not give medical advice. We do not inspect pharmacies. A UK prescriber decides whether a treatment suits you.

How we make money

Some pharmacy links and codes come from partnerships. A partner may pay us a commission when you order. We also license the database to companies who want live feeds. Partnerships never change the price order, the median or the rank. Pharmacies with no partnership appear in the same tables, ranked by the same rule.

How to check us

• Open any pharmacy website and compare the price with ours. Each page shows the export time.
• Read the methodology and the editorial policy.
• Download the full price file and check the sums yourself.
