Frequently asked

How does the reconstitution calculator work?
Enter the amount of peptide in the vial (mg), the volume of bacteriostatic water you added (mL), and your target dose. The app shows the exact volume and syringe units, concentration, and how many doses the vial holds.

Is the app free?
Yes — the reconstitution calculator is free to use. Peptide & Co. Pro, including the dose log, dosing schedules with reminders, and vial inventory, is available by subscription with a 3-day free trial.

How do I manage or cancel my subscription?
On your iPhone or iPad, open Settings → [your name] → Subscriptions, select Peptide & Co., and choose your plan or cancel. Cancel at least 24 hours before the end of the current period to avoid the next charge.

I already subscribed but a new device shows the paywall.
Open the paywall and tap Restore purchases while signed in with the same Apple ID you used to subscribe.

Where is my data stored?
Entirely on your device. We do not collect or transmit your calculations, log, schedules, or inventory. See our Privacy Policy.

Do reminders work when the app is closed?
Yes. When you create a dosing schedule and allow notifications, the app schedules local reminders on your device that fire at your set times.
