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.

Milligrams to clicks to millilitres, for every pen strength, with the arithmetic shown so you can check it. Doses per pen and cost per dose too.

Resting and total daily energy expenditure, and the intake a given rate of loss would need. Mifflin–St Jeor and Katch–McArdle, both written out.

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

Most comparisons list a headline price per pen and stop. That is not a comparison — it is a coincidence. We normalise before we rank.
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.
We are not collecting addresses yet — the mailbox that will hold them is still being set up, and we would rather not take your email before there is somewhere proper for it to live. Check back shortly.
GLP Master is an information and record-keeping project. No medicines are sold, supplied, promoted or advertised on this site, and nothing here is medical advice or a recommendation to start, stop or change any treatment. Decisions about prescription medicines belong with you and your own prescriber.
