Questions

Does Pro work in the iPhone and Android apps too?

Yes. Pro belongs to your Peptide Library account. Sign in to the app with the same email and Pro unlocks automatically, wherever you bought it.

I already subscribe in the app. Do I need to buy again?

No. Sign in on the web with the same account and Pro is already on. Buying again would charge you twice, so the website shows your existing plan instead.

How do I cancel?

Web purchases: open Account → Subscription and choose Manage subscription. App Store and Google Play subscriptions are cancelled in the store’s subscription settings. Pro stays on until the end of the period you paid for.

Will I be charged automatically?

Monthly and Yearly renew automatically at the price shown until you cancel. Lifetime is a one-time payment and never renews.

Can I get a refund?

You can ask for a full refund within 14 days of your first payment for a web purchase. See the refund policy for details. App Store and Google Play purchases are refunded by Apple and Google.

Which payment methods can I use?

Credit and debit cards, and Apple Pay or Google Pay when your device and browser support them.

Is Peptide Library medical advice?

No. Peptide Library is a research and tracking tool. It does not diagnose, treat or recommend anything; talk to a qualified professional about your health.
