How can we help?
Need a hand? Email support@peptune.app — include your iPhone model and iOS version, and we'll get back to you, usually within a couple of days.
A note first: Peptune is an educational logging tool, not a source of medical advice. We can help with how the app works, but we can't advise on your protocol or dosing — that's a conversation for a qualified healthcare professional.
How does the reconstitution calculator work?
Enter your vial strength, the amount of BAC water you're adding, and your target dose. Peptune does the arithmetic and shows the draw line on a live syringe. It's math only — it converts the numbers you type and does not recommend a dose. Always verify the result yourself before relying on it.
Does my data leave my phone?
No. Everything you log — compounds, doses, sites, and vials — is stored on your device. It's never uploaded to us or shared with anyone. See our Privacy Policy for the full details.
Do I need an account?
No. Peptune has no accounts and no sign-in. You open the app and start logging. Because your data is stored on the device, keeping your iPhone backed up (for example, through iCloud) is the way to preserve it.
What's free, and what's Peptune Pro?
Peptune is free to start, with the compound library and reconstitution calculator available at no cost. Peptune Pro unlocks the full toolkit — injection-site rotation, vial inventory with supply and expiry alerts, and unlimited protocol tracking. Pro is available as an annual plan with a 3-day free trial, or a monthly plan.
How do I manage or cancel my subscription?
Subscriptions are handled by Apple. On your iPhone, open Settings → [your name] → Subscriptions → Peptune to change or cancel your plan. If you cancel, your Pro access continues until the end of the current billing period.
How do I restore a purchase?
If you've bought Pro and it isn't showing, open the Peptune Pro screen and tap Restore Purchases. Make sure you're signed in with the same Apple Account you used to buy.
How do I request a refund?
Refunds for App Store purchases are handled by Apple. Visit reportaproblem.apple.com, sign in, and choose the Peptune purchase to request a refund.
Still stuck?
Email support@peptune.app with a short description of what happened, your iPhone model, and your iOS version. Screenshots help. We read every message.
