FAQ
Frequently asked questions
Quick answers about concentration math, mcg-to-mL conversion, blends, tracking preparations, offline use, privacy, reminders, backups, exports, and support.
Is this medical advice?
No. PepCalc Pro is an informational and organizational tool only.
Does the app work offline?
Yes. All calculations and records are stored locally on your device.

How do I convert mcg to mL?
mcg (mass) and mL (volume) are different units; you need your vial’s concentration (e.g. mcg/mL) to convert between them.
Learn more: How to convert mcg to mL without guesswork.
How does concentration (mcg/mL) work?
Concentration is mass per unit volume (e.g. 5 mg in 1 mL = 5000 mcg/mL). The app uses this to compute doses and volumes consistently.
Learn more: Understanding concentration math.
Why do different peptide calculators give different results?
Differences usually come from rounding, unit choices, or how concentration is entered. Using one consistent method and checking the math avoids confusion.

How do I track multiple preparations without mixing them up?
Keep each preparation separate (vial, concentration, schedule). The app lets you name and track preparations so you always know which one you’re dosing from.

Can I calculate for a blend with more than one component?
Yes, from version 1.2. Switch the Calculator to Blend, choose the number of components (2 to 6), and enter the amount of each one from your label. The result shows the units to measure and how much of each component that measurement contains. The app does not supply names, amounts, or ratios. If your label only gives a total, use Single mode with the total amount.

Why is offline-only important for peptide calculations?
Offline-only keeps calculations and schedules on your device, with no servers or accounts. That reduces mix-ups and keeps the app a simple utility, not a platform.

Do you collect user data?
No. PepCalc Pro does not collect analytics or track users.
How do reminders work?
Reminders use local notifications on your device. No remote servers are involved. The app schedules upcoming reminders each time you open it, so open it from time to time.
How do I back up or restore my data?
Your data is stored only on your phone. From version 1.2, go to Settings → Backup & restore and tap Create backup to save everything to one file, then keep that file outside the app (Files or iCloud Drive). Restore from backup loads it again, for example on a new phone. Restoring replaces what is in the app. Without a backup file, deleting the app removes your data.

Can I export my records?
Yes. Logs can be exported as CSV or PDF.
How do I delete a record I added by mistake?
From version 1.2, open the record from the Records tab and tap Delete Record at the bottom. If it had deducted from a vial, the amount is returned to the vial.
How do I report a bug or request a feature?
Use the Support page or the Enhancement request form.
