About GLP1Meter

A set of free calculators for people already taking, or already prescribed, a GLP-1 medication. This page exists so you can judge how much to trust the numbers.

Who writes this: I’m Gavin. I research, build and maintain GLP1Meter on my own, and I take a GLP-1 medication myself — I built these tools because I needed them. I am not a doctor, pharmacist or nurse. Nothing here is clinically reviewed and I do not claim otherwise; what I offer instead is traceability. Every dosing figure links to the FDA-approved label it was copied from, and every conversion is arithmetic you can redo on paper. Last reviewed August 2026.

What it does

Two calculations cause most of the confusion around these medications. The first is milligrams to syringe units — trivial arithmetic, but a real source of error because the answer changes with vial concentration. The second is cost, where quotes arrive in incompatible units and cannot be compared without normalising them. This site does both, plus reproduces the published titration schedules in a readable form. It currently covers 218 questions.

What I actually bring to this

Not a medical qualification — I say so plainly above and everywhere else on this site. Two other things, though.

The first is that I am on a GLP-1 myself. This site exists because I needed it: standing there with a vial, a syringe and a dose written in milligrams, doing arithmetic nobody had laid out properly anywhere. It is also why the cost calculator asks for your quote instead of publishing a price — the quotes I was given came in four different units and none of them were comparable. First-hand use is not medical expertise and I do not present it as any, but it is why the tools here address the problems people actually hit rather than the ones that are easy to write about. You will not find my personal results anywhere on this site, because what happened to one person is not evidence and would only mislead you.

The second is the part most GLP-1 content skips: reading the primary documents properly and being obsessive about transcription.

Every titration schedule here I read out of the manufacturer’s own prescribing information, rather than lifting it from another website that lifted it from a third. I re-checked all 8 line by line against the current labels in August 2026, and the table below records the date of each check. The compounding rules — which have moved repeatedly since 2024 and are still moving — are tracked continuously and re-dated every time they shift, rather than written once and left to rot. The 218 questions covered were chosen from what people actually search for, not from what is comfortable to write about, which is why some pages exist mainly to say “the premise of this search is wrong.”

That is research, not authority, and the difference matters. Research means you can check my work — so all of it is laid out below for exactly that purpose.

Why there is no medical reviewer

Plenty of health sites carry a “medically reviewed by” byline. I could not add one honestly, so I did not add one at all. Inventing credentials on a page about injectable medication would be a lie with real consequences, and a name attached to a page nobody actually read is worth nothing anyway.

What I do instead is narrower but verifiable: publish only what the label already says, cite the exact label, timestamp the check, and refuse the questions that genuinely need a clinician. If a page here ever tells you what dose to take, it has gone wrong — tell me.

How each kind of number is produced

Dosing schedules

Transcribed from the FDA-approved prescribing information for each product and checked step by step against the current label. Nothing is averaged, adjusted or inferred — if the label does not state it, it is not on this site. Every schedule links to the label it came from, so you can check the transcription yourself in about thirty seconds.

Milligram-to-unit conversions

Arithmetic, not medicine: units = (dose ÷ concentration) × 100 on a U-100 syringe. The formula is shown alongside every result specifically so you can verify it by hand. It carries no clinical judgement, and it is only correct for the concentration printed on your own vial.

Prices

Not published. GLP-1 pricing moves faster than any static page can track, so the calculator asks for the quote you were actually given rather than quoting a figure at you. A number published here today would be misleading within weeks, and a wrong price is worse than no price.

Regulatory status

Only events that have already happened and can be checked against a primary source — a published rule, a Federal Register notice, an FDA statement. Every such block carries the date it was last confirmed. I do not predict what regulators will do next.

What is deliberately absent

No efficacy claims, no safety comparisons, no suggestion of which product or dose suits you, and no personal anecdotes presented as evidence. Those questions require someone who can examine you and has access to your history. This site cannot do either, so it does not try.

Sources

Dosing schedules on this site come from the current FDA-approved prescribing information for each product. Below is every label used, when the manufacturer last revised it, and when I last checked my transcription against it. The links go to DailyMed, the US National Library of Medicine’s label archive, not to a summary of it.

• DailyMed (US National Library of Medicine) — The current FDA-approved prescribing information for every product on this site. Each drug below links to its own label.
• FDA — human drug compounding — The regulatory position on compounded GLP-1 products, which changed substantially through 2025–2026.

When this gets updated

Labels change. When one does, the transcription here is re-checked line by line against the new version and the dates in the table above move. That is the only thing that moves them — the review date is not refreshed to look current, because a date that does not correspond to an actual check is worse than no date. Compounding regulation is tracked separately and carries its own “as of” date on the pages where it appears, because it has changed faster than anything else in this field.

What it is not

This site provides calculators and reference information about GLP-1 medications. It is not medical advice, does not diagnose or treat any condition, and is not a substitute for your prescriber. Dosing information is reproduced from published prescribing information; always follow the instructions that came with your own prescription.

How it makes money

Some outbound links are affiliate links, and I may earn a commission if you use them. I disclose this on every page where such a link appears, and the links are marked sponsored nofollow so search engines treat them as paid placements. I do not sell medication, do not take payment to appear in a comparison table, and do not accept sponsored articles.

Two rules keep this from bleeding into the data. First, no affiliate link appears on the compounded-medication pages at all — those pages describe a tightening regulatory position, and running ads for the products they discuss would make them worthless as a reference. Second, the calculators know nothing about commissions: no product is ranked, ordered, or defaulted-to based on what it pays, and the arithmetic returns the same number regardless. If either stops being true, this section is the lie and you should stop trusting the rest.

Corrections and contact

If you find an error in a dosing schedule or a conversion, it is a bug and I want to know. Accuracy on this kind of page matters more than coverage — email [email protected], ideally with the page URL, and I will check it against the label and fix it. I correct published figures in place and move the review date when I do.

The same address works for anything else: partnership enquiries, questions about how a calculator arrives at its number, or a request to cite this data.
