How can we help?

No. Peptific works with no account and no sign-up. Your protocols, vials, and injection records are stored locally on your iPhone. Peptific does not upload your protocol contents to our servers.

It's pure arithmetic on the numbers you enter. Tell it your vial amount, the water you're adding, and your own target dose; Peptific computes concentration, volume, and syringe unit line from those inputs. It never determines or suggests a dose; the numbers are always yours.

No. Peptific is a logging and math tool. It does not provide medical advice, dosing recommendations, treatment guidance, or emergency support. Every value is entered by you, and you should talk to a licensed provider about your health.

The free core covers one protocol, logging, one reminder, and the first-vial calculator. Pro unlocks the stack — multiple compounds on one schedule, unlimited vials, CSV export, and advanced charts. Pro is $39.99/year or $9.99/month with a 7-day free trial.

Your logged history is never locked. If Pro ends, your data stays on your device and remains exportable — only the Pro-only features become unavailable. Cancel during the trial and you keep access until it ends.

Export your full history as a CSV from the app's Settings (Pro). You can delete your data from within the app at any time, and removing the app clears local data from your device.

Peptific is a native iPhone app built for current versions of iOS. The calculator on this website works in any modern browser.
