Is Peptide IA a medical device or medical advice?

No. Peptide IA is an educational and research-tracking tool. It does not diagnose, treat, or provide medical advice. Always consult a licensed physician about your protocol.

Where is my data stored?

Everything stays on your device by default. No accounts required. You can export your data anytime or wipe it with a single tap.

Does the reconstitution calculator support any vial size?

Yes. Enter peptide weight, bacteriostatic water volume, and target dose — get exact units on a standard insulin syringe.

Which peptides are in the library?

BPC-157, TB-500, GHK-Cu, semaglutide, tirzepatide, tesamorelin, ipamorelin, CJC-1295, sermorelin, MOTS-c, AOD-9604, HGH fragment 176-191, Melanotan II, PT-141, Epitalon, DSIP, Selank, Semax, and more — each with typical reported doses, half-life, and storage notes.

Do I need an internet connection?

No. Peptide IA works fully offline. Optional iCloud/Google Drive backup is available if you want it.

How much does Peptide IA cost?

Peptide IA is €7.99 per week (with a 3-day free trial) or €79.99 per year (no trial — yearly saves about 81% vs paying weekly). Both plans include every feature. Subscriptions renew automatically and can be cancelled anytime in your App Store, Google Play, or Stripe account.
