What GLP-1 treatment costs you: keeping a record

By Tessaro Pty Ltd, the maker of Pepti · Reviewed November 2026 · For adults 18+

“Nobody mentioned that at signup.” “…it’s not long-term sustainable for me.” The price of the medicine, and whether a plan covers it, is one of the biggest worries on a weekly GLP-1. No tracker changes a price. This page is about keeping a plain, dated record of what you actually pay, so the conversations you have about it start from facts.

Cost is why many people stop

In a 2025 national survey of US adults who had stopped a GLP-1 medicine, cost was the most-cited reason for stopping, ahead of side effects and lack of insurance coverage, and almost a third said they first filled their prescription without insurance (DiStefano et al., 2026). In a large US health-records cohort, higher income was associated with lower rates of stopping among people with type 2 diabetes (Rodriguez et al., 2025). In a survey at one US academic medical centre, people described prior-authorisation delays and out-of-pocket cost among the main disruptions to their care, and the feature they most wanted from a digital tool was one place to keep track of refills, prior authorisation and appointments (Chen et al., 2026).

A tracker cannot lower the price of a medicine or change what a plan covers. What it can do is replace a vague sense that “this is costing a lot” with a dated list of what you actually paid. That list is what you need when you talk to your prescriber, your pharmacist or your insurer about the choices open to you.

What to write down

• What you paid, and when — the amount on the receipt for each pen or vial, and the date. Not an estimate.
• How it was paid — whether insurance covered part of it, and what you paid out of pocket.
• Coverage events — a prior-authorisation request and the date of the decision, a denial, a change of plan, a change at renewal.
• Gaps — any stretch where cost or coverage delayed a shot, so the gap reads as what it was rather than as a missed habit.
• Questions — written down when they occur to you, for the next appointment or the next call.

Keep the receipts as well. The record is your summary of them, not a replacement.

Why the dates matter

Prices and coverage change, sometimes without much warning. A record with dates shows when a change happened and what it did to your monthly spending. It also tells your prescriber where a gap in your shots came from, which helps them read the rest of your record correctly: a stretch with no shots looks the same in a log whether it was a choice, an illness or a pharmacy that could not fill the prescription.

Over a few months the same record shows the pattern of what you have spent, month by month, which is easier to plan around than a single painful receipt.

What a record cannot do

A record cannot tell you whether a lower-cost option is right for you, whether to change products, or whether to space out your shots to make a supply last longer. Those are clinical decisions. Changing your schedule to save money is something to raise with your prescriber before you do it, not something to decide alone.

It also cannot predict a price. What you paid last month is a fact; what you will pay after a plan change is not, and this page makes no claim about any price or programme.

How Pepti keeps it

In Pepti you can type the price you paid on each vial or pen, in your device’s currency, alongside its date. The Spending card on Progress adds up what you typed: “Spent this month”, and the amount spent on each compound. The totals are sums of the prices you entered and nothing else. Pepti never works out a cost per shot or per milligram, and it does not compare prices or point you anywhere to fill a prescription.

Appointments you add in Settings get a reminder the day before, and the clinic report you share from Progress keeps your shots, weights and side effects together for that visit.

Common questions

Can a tracker lower what I pay for a GLP-1?

No. A tracker cannot change a price or what a plan covers. It can give you a dated record of what you paid, which helps when you discuss the choices open to you with your prescriber, pharmacist or insurer.

What should I record about cost?

The amount you paid for each pen or vial and the date, whether insurance covered part of it, any prior-authorisation decisions or coverage changes, and any delay in your shots that cost or coverage caused.

Should I space out my shots to save money?

That is a clinical decision to discuss with your prescriber before changing anything. A record of what you have paid and when your shots happened makes that conversation specific.

How does Pepti show spending?

You type the price paid on each vial or pen. The Spending card on Progress shows the month's total and the total per compound, as sums of what you typed. It never works out a cost per shot or per milligram.
