GLPmaster In build — launching 2026

The GLP-1 record, built like a clinical record.

Two things, done properly: a place to track what actually matters while you're on incretin therapy, and a price comparison that compares like with like. Built by someone taking these medicines, who also reads the trial data for a living.

What's coming

First

Tracking that behaves like a clinic record

Not a mood diary with a weight box. One timeline, with the reference ranges and risk thresholds a clinician would actually use.

  • Weight, BMI, waist, waist-to-height — against centiles, not vibes
  • Bloods — HbA1c, full lipid panel, ApoB, ALT, renal, with targets on the chart
  • Blood pressure and fitness — including VO₂max where you have it
  • Dose history — titration, gaps, and what changed when
  • Progress photographs — private by default, yours to delete
  • One page you can hand to your GP — printable, properly referenced

Alongside

Price comparison that isn't quietly wrong

Most comparisons list a headline price per pen and stop. That is not a comparison — it is a coincidence. We normalise before we rank.

  • Cost per milligram, per dose and per month — not per box
  • What's included — consultation, needles, follow-up, delivery
  • Checked and dated, so a stale figure is visible as a stale figure
  • Registration shown for every pharmacy listed

Why this, and why us

Because people on GLP-1 medicines deserve tools built to the standard of the evidence behind the drugs themselves. There is a great deal of good work out there already; what we want to add is a set of tools where every number can be traced to its source, and where the working is shown rather than asserted.

GLP Master is being built by a qualified doctor of over a quarter of a century and a highly respected NHS consultant of more than 16 years. He is also a software developer and, importantly, a GLP-1 user with skin in the game, who has a deep understanding of your journey — because he is also on it himself. That combination is the whole point: the features come from using the thing, and the rigour comes from the day job.

So: no transformation photography, no "incredible results", no invented scores. Where a number has a confidence interval, you will see the confidence interval. Where a figure is a week old, it will say so. Where the evidence is thin, it will say that too.
