OVERVIEW
What is EML?
Estimated Medication Level (EML) is a number, in milligrams (mg), that estimates how much GLP-1 medication is currently active in your body. It's calculated from your logged doses and your weight, and it moves the way your medication actually moves — climbing after a dose, then gradually tapering until your next one.
EML applies a mathematical model to approximate GLP-1 medication levels in the bloodstream, drawing on published pharmacokinetic research on tirzepatide, semaglutide, and dulaglutide. These estimates describe how the medication typically behaves over time across a population.
EML is available to all Signos members logging their GLP-1 medications in the Signos app. It's built to help you understand your medication's rhythm — it isn't a lab measurement, and it isn't used to guide dosing decisions.

GLP-1 PROGRAM
EML number
Your current estimated medication level, shown in mg on your home screen.
|
GLP-1 PROGRAM
Phase indicator
A simple word and arrow showing whether your level is rising, peaking, tapering, or clearing.
|
| ℹ |
EML is an estimate, not a measurement.
It's modeled from your dose history and weight, so it gives
you a helpful picture of your medication's rhythm — not an
exact clinical reading.

HOW-TO
How to view your EML
Once EML is available on your account, you'll find it right on your home screen. Here's how to make the most of it.
From the Home screen
1 |
Find your EML card
Look for the EML card on your home screen. It shows your medication, dose, and current mg level at a glance.
|
2 |
Tap for more detail
Tap the card to open the info sheet, which explains what your current value means and walks through each phase of your cycle.
|
3 |
Scrub your glucose graph
Drag your finger across the glucose graph to see your EML at any past moment — it updates as you scrub and returns to today's value when you let go.
|
| * |
Log doses as soon as you take them.
Your EML recalculates every time you log, edit, or delete
a dose — so logging promptly keeps your number as accurate
as possible.
|
| ! |
EML doesn't replace guidance from your care team.
This feature is here to help you understand patterns in how
you feel — it isn't a diagnostic tool and shouldn't be used
to adjust your dose or schedule. Always follow your prescriber's
instructions.

HOW-TO
Understanding your phase indicator
Next to your EML number, you'll see a word and an arrow that describe where you are in your dose cycle. Together, they turn a single number into a story about your week.
Rising means your level is climbing after a recent dose. Peaking means you're near the highest point of your current cycle. Tapering means your level is gradually coming down. Clearing means you're approaching the end of your cycle, close to your next scheduled dose.
Your phase indicator updates automatically — there's nothing you need to log beyond your regular doses.
REFERENCE
Which medications support EML
EML is available for the most commonly logged GLP-1 medications. Support for additional medications may expand over time.
| Medication | Dosing schedule | EML supported |
|---|---|---|
| Tirzepatide | Weekly injection | Yes |
| Semaglutide (injection) | Weekly injection | Yes |
| Semaglutide (oral) | Daily | Yes |
| Dulaglutide | Weekly injection | Yes |
| Compounded or other GLP-1 medications | Varies | Not yet |
TROUBLESHOOTING
Troubleshooting & FAQs
| What's happening | What to try |
|---|---|
| I don't see an EML card on my home screen. | Confirm your GLP-1 program is turned on in Settings → Programs & Widgets, and that your logged medication is one of the supported types listed above. |
| I just started my medication and don't see a number yet. | This is expected. EML appears once you've logged your first dose, and it may take a few doses to reflect your full pattern. |
| My EML number doesn't look right. | Check that your recent doses are logged accurately in milligrams, and that your current weight is up to date — both feed directly into your estimate. (EML does not currently support doses logged in units.) |
| Why is my EML lower than my dose? |
Your dose and your EML measure two different things. Your dose is the full amount you take. After an injection, that medication diffuses throughout your body, into different tissues, while your body steadily clears some out. EML tracks just the amount in your bloodstream — because the blood level is the active part, the piece that drives how the medication works. That's why it reads lower than your dose: it's showing the active level in your blood, not everything spread across your body. The level rises after a dose and tapers before the next, so it shifts across the week. |
| My phase indicator hasn't changed in a while. | This can happen if a dose is overdue to be logged. Log any missed entries and your phase will update automatically. |

falling alongside your glucose over time — so you can see
the full shape of your cycle, not just today's number.
