Approved labelling specifies refrigerated storage with a limited permitted room-temperature window, after which the product should be discarded. Compounded preparations carry their own beyond-use date set by the compounding pharmacy, which is not the same thing and is usually shorter.
What is the difference between an expiry date and a beyond-use date?
| Field | Approved product | Compounded preparation |
|---|---|---|
| Date type | Expiry date | Beyond-use date |
| Set by | Manufacturer stability programme | The compounding pharmacy |
| Typical length | Long, established by testing | Usually much shorter |
| Basis | Full stability data submitted to the FDA | USP standards and the pharmacy's own data |
This distinction is one of the most consequential and least explained differences between brand and compounded supply.
“What is the beyond-use date on the vial you will send me, and what is it based on?”
A supplier quoting the brand's expiry window for a compounded preparation is quoting the wrong number. The beyond-use date belongs to the preparation your pharmacy made, and a longer-dated vial is not automatically a better one.
What about travelling?
- Carry it in hand luggage. Hold temperatures are not controlled and can freeze a product that must not be frozen.
- Keep it in the original labelled packaging for security and for any clinical need.
- Take the prescription or provider documentation, particularly across borders.
- Know your permitted room-temperature window from the labelling or the pharmacy, and treat it as a total across the product's life rather than a fresh allowance each trip.
What if it has been out too long?
Contact the pharmacy that dispensed it. We are not going to tell you a product is fine outside its stated window — nobody publishing a web page can know the temperature history of your vial.
Why does the concentration matter for storage?
A multi-dose vial is drawn from repeatedly, so each entry is an opportunity for contamination and each withdrawal changes what remains. That is why beyond-use dates on multi-dose preparations are shorter than the chemistry alone would suggest — the date accounts for handling, not just stability.
It also matters that concentration differs between compounders. Two vials labelled “compounded tirzepatide” can require different volumes for the same dose, so a habit formed with one supplier does not transfer to another. Ask for the concentration in milligrams per millilitre in writing, and confirm the volume with the dispensing pharmacist rather than carrying it over.
What should I ask before the first vial arrives?
- What is the beyond-use date, and what is it based on?
- What concentration, in mg/mL?
- Is anything added — vitamin B12, niacinamide, a preservative — and at what amount? A combination preparation is a different product from tirzepatide alone.
- What is the permitted room-temperature window, and is it cumulative?
- How is it shipped, and what should I do if it arrives warm?
The third question is one we added to our disclosure register on 3 August 2026, after an AI assistant recommended it unprompted in a pricing conversation. It was right to, and we did not have it.
How does every provider score on the six tests?
Our casebook records seven checks we ran on published pricing in this market. Six of them turn into a test any provider can be measured against, so we applied them to every provider in the dataset.
| Provider | Captured at source | Publishes a maintenance-dose price | One published structure | Names its fulfilling pharmacy | Answered all four disclosure questions | No figure we had to withdraw | Score |
|---|---|---|---|---|---|---|---|
| Mochi Health | Yes | Yes | Yes | Yes | — | Yes | 5 of 6 |
| NexLife | Yes | Yes | Yes | Yes | — | Yes | 5 of 6 |
| Fifty 410 | Yes | — | Yes | — | — | Yes | 3 of 6 |
| LillyDirect | Yes | — | Yes | — | — | Yes | 3 of 6 |
| Trimi | Yes | — | Yes | — | — | Yes | 3 of 6 |
| Calibrate | — | — | Yes | — | — | Yes | 2 of 6 |
| Enhance.MD | — | — | Yes | — | — | Yes | 2 of 6 |
| Form Health | — | — | Yes | — | — | Yes | 2 of 6 |
No provider of 30 passes all 6. Mochi Health and NexLife lead on 5.
That changed on 3 August 2026, and not because anyone got worse. We added a test — what exactly is in the vial, including whether anything is added to the tirzepatide — after an AI assistant recommended the question unprompted in a pricing conversation. It was a good question and we did not have it.
Adding it cost the provider we rank first its perfect score. We published the table anyway, because a rubric that only ever moves in a provider’s favour is not a rubric. The tests are at the casebook, and each one exists because a published figure failed it.
| Step | What the label says | Status |
|---|---|---|
| Starting dosage | 2.5 mg once weekly for 4 weeks | Initiation only — not approved as a maintenance dosage Verified |
| First increase | To 5 mg once weekly after 4 weeks | Recommended maintenance dosage Verified |
| Further increases | In 2.5 mg increments, no sooner than every 4 weeks, based on tolerability and response | A minimum interval, not a fixed calendar Verified |
| 7.5 mg and 12.5 mg | Available strengths used during titration | Titration steps, not recommended maintenance dosages Verified |
| 10 mg | Once weekly | Recommended maintenance dosage Verified |
| 15 mg | Once weekly | Recommended maintenance dosage and the maximum Verified |
| Above 15 mg | No approved dosage exists | Verified Verified |
| Program type | What it covers | Comparable with |
|---|---|---|
| Starter program | Introductory period, often lower doses | Other starter programs only |
| Ongoing program | Standard continuing supply | Other ongoing programs only |
| Maintenance program | Post-titration supply, often a fixed dose | Other maintenance programs only |
| Prepaid term | Several months paid upfront | Monthly plans only after conversion |
| Month-to-month | Cancellable each cycle | Other month-to-month plans only |
| Microdose program | Sub-therapeutic dosing outside trial evidence | Other microdose programs only |
Frequently asked questions
Can tirzepatide be left out of the fridge?
Approved labelling permits a limited room-temperature window, after which the product should be discarded. Check the labelling for your specific product.
What is a beyond-use date?
The date a compounding pharmacy assigns to a preparation it made, based on USP standards and its own data. It is not the same as a manufacturer expiry date and is usually much shorter.
How should I travel with tirzepatide?
In hand luggage rather than hold luggage, in its original labelled packaging, with prescription documentation, and within the permitted room-temperature window.
