Use your prescription, medication label, and guidance from a licensed clinician or pharmacist when deciding what and how much to take.
Add your first pen or vial
Keep the original packaging nearby. ShotNest organizes what you enter; it does not authenticate a product or check your prescription.
- Open Supply and tap the + button.
- Choose label scanning or manual entry. If scanning, photograph the relevant label clearly; you can review the result before saving.
- Check the medication, container form, quantity, strength or concentration, source, and label dates against the actual packaging. Fields vary by product.
- Correct missing or misread details. If a label is unclear, ask your pharmacist before entering a value.
- Save, then open the supply record to review its details. Add the other containers you want to track.


Source label photos stay on the iPhone where you added them. Read how label photos are handled.
Connect recorded shots to their supply
In Log Shot, review the Supply source along with the medication, dose, date, time, and injection site. Use Change if the selected source is not the container you actually used. Save only after the record reflects what happened.
Then check Supply to see the recorded amount remaining. If you add an older shot or edit history, read any supply-adjustment prompt carefully: a historical record and a change to current inventory are not always the same thing.
Keep label details and dates with each container so similar-looking pens or vials do not have to be identified from memory. For a full recording walkthrough, see the shot tracking guide.
A simple supply example
Imagine you record four unopened single-dose pens from your own prescription. After you log two shots, each linked to one of those pens, the inventory should reflect two unused pens remaining, assuming the original entries and links are correct.
If one pen is damaged or discarded without a shot, a shot log alone cannot explain that difference. Review the container record and reconcile what is actually on hand. Never log a shot you did not take just to change inventory.
This is an inventory example, not a recommendation for medication, strength, or frequency. The refill projection also depends on your saved plan and can change when that plan changes.
How estimates can help
An estimate can help you notice when it may be time to plan a refill. The actual amount can differ because of the container, measurement, waste, device use, or a prescription change.
Check the container and official label. Never use an estimate to improvise a dose or decide whether medication is safe to use.
Review every label detail
ShotNest can scan a label on your iPhone to help fill in selected details. Compare every detail with the original label before saving it. Label photos stay on the iPhone where you added them.

If the remaining supply looks wrong
- Check the starting record: quantity, form, strength, and concentration must describe the actual container. Milligrams and milliliters are not interchangeable.
- Check shot history: look for missing or duplicate records and a shot linked to the wrong supply source.
- Check what happened outside the app: lost, damaged, or discarded medication may not be represented by a shot record.
- Check dates separately: having medication remaining does not establish that it is within its expiry or permitted use period.
If you still cannot reconcile the record, contact support about the app. Ask your pharmacist about unclear label information; support cannot decide whether medication is safe to use.
Medication safety comes first
Products and instructions can differ. Follow the packaging and directions from your prescriber and pharmacy. Contact a licensed clinician or pharmacist if the label, concentration, amount, storage, appearance, source, or schedule is unclear.
The FDA advises patients to obtain semaglutide and tirzepatide with a prescription from a licensed clinician and fill it at a state-licensed pharmacy. The FDA also describes added concerns with unapproved versions of these medications.
