The problem

Most people track peptides in the worst way possible.

Tracking a peptide protocol shouldn’t feel like running a research lab. Peptid AI removes the guesswork so you can focus on results, not logistics.

Without Peptid AI

  • Scribbled doses in a notes app you forget to open
  • Reconstitution math redone every single vial
  • No idea which cycle day you’re on this week
  • Spreadsheets that fall apart on your phone

With Peptid AI

  • Tap to log — your protocol fills in the rest
  • Built-in reconstitution and dosage calculators
  • Cycle day, next dose, and adherence at a glance
  • Works offline, on phone and tablet
How it works

FAQ

Questions, answered.

Is Peptid AI a medical device or medical advice?
No. Peptid AI is an educational and research-tracking tool. It does not diagnose, treat, or provide medical advice. It does not source, supply, or recommend any substance. Always consult a licensed physician before starting, changing, or stopping any protocol.
Does Peptid AI tell me what dose to use?
No. Peptid AI never prescribes a dose. The peptide library shows typical ranges reported in research literature for context, but every dose you log is one you and your physician set together. The app is a clean log — not a coach.
Where is my data stored?
Peptid AI works offline-first, then syncs your data to your private, EU-hosted account (Supabase) so it is safe across devices. No manual sign-up is needed to start — an anonymous account is created for you, and you can sign in with Apple or Google to keep your data if you switch devices. Export your full log as TXT or JSON anytime, or delete everything with a single tap.
Do you sell my data or use tracking?
No. We do not sell, rent, or share your personal data, and we run no advertising SDKs or ad-tech analytics. The third parties that process data are our EU cloud host (Supabase) for storage and sync, Apple/Google for app distribution and payments, and — only when you use the optional AI assistant — the AI provider that powers it. See the Privacy Policy for the full list.
Does the reconstitution calculator support any vial size?
Yes. Enter peptide weight (mg), bacteriostatic water volume (ml), and target dose (mcg or mg) — the calculator returns exact units on a standard 100-unit insulin syringe. Presets exist for BPC-157, TB-500, GHK-Cu, ipamorelin and others.
Which peptides are in the library?
159 entries spanning recovery (BPC-157, TB-500, MGF, PEG-MGF, KPV, LL-37), growth hormone (sermorelin, CJC-1295, ipamorelin, GHRP-2/6, hexarelin, tesamorelin, somatropin, AOD-9604, HGH Fragment 176-191), GLP-1 / metabolic (semaglutide, tirzepatide, retatrutide, liraglutide, dulaglutide, exenatide, cagrilintide), skin & tan (GHK-Cu, AHK-Cu, melanotan I and II), cognitive (selank, semax, noopept, DSIP), longevity (epitalon, NMN, NR, NAD+, NADH, MOTS-c, SS-31, glutathione), hormones (HCG, gonadorelin, kisspeptin, oxytocin, PT-141) and more. Each entry shows typical doses, route, half-life and cautions.
Can I track stacks and multiple cycles?
Yes. The stack manager runs multiple peptides in parallel with independent schedules. Cycle history is preserved across years — your fifth BPC-157 cycle stays visually linked to the first four for comparison.
Can I export my data to share with a doctor?
Yes. The Doctor export tool builds a report from the sections you choose — protocols, doses, estimated serum levels, sleep, mood, journal and more — to copy or share. Settings also exports everything as TXT or JSON.
Do I need an internet connection?
Not to use it day to day. Peptid AI works offline-first — the library, calculator, and logging all work without a connection — and your data syncs to your private, EU-hosted account when you are back online so nothing is lost.
Will my data sync across iPhone, iPad, and Android?
Yes. Your data syncs through your private, EU-hosted account (Supabase), so it stays in sync across iPhone, iPad, and Android. Sign in with Apple or Google to link your devices; you can also export TXT/JSON anytime.
How is this different from a spreadsheet or notes app?
Spreadsheets do not nag you, do not own the reconstitution math, do not show you trends without manual chart work, and become unreadable by week 4. Peptid AI owns the schema so you spend time running your protocol — not maintaining a tab full of colour-coded cells.
How much does Peptid AI cost? Is there a free trial?
Weekly with a 3-day free trial for new subscribers, or yearly with no trial — yearly works out to roughly a fifth of the weekly price and saves about 81%. Both unlock Premium: unlimited protocols and vials, and the AI Coach. Without one the app stays free, with 1 active protocol at a time and up to 3 vials. Cancel anytime in your App Store or Google Play account. The trial converts to a paid Weekly subscription unless cancelled at least 24 hours before it ends. Prices are shown in your local currency on the pricing section above.
