Frequently Asked Questions

How do I calculate a reconstitution?

Open PepSync, enter your peptide amount (in mg), add your BAC water volume (in mL), and the app instantly calculates the concentration. Enter your desired dose and the syringe fill indicator shows exactly how much to draw.

Where is my data stored?

All data is stored locally on your device. PepSync has no cloud, no accounts, and makes no network requests. Your data never leaves your phone.

Can I add custom peptides?

Yes. In addition to the 32+ pre-loaded peptides, you can enter any custom peptide amount manually for your calculations.

Will I lose my data if I update the app?

No. App updates preserve your saved protocols and injection logs. However, uninstalling the app will permanently delete all local data.

I found a bug. How do I report it?

Email support@pepsync.app with a description of the issue and your device model / OS version. We'll get back to you promptly.
