Built by someone who actually runs peptides. Unlimited protocols, the calculator, and the full cited library — free. Pro is a one-time $44.99, no subscription.
What it does
The calculator is the hero. The library is the source of truth. And Pro tracks the whole protocol — on the App Store and Google Play.
Forward and reverse modes. Vial + water + dose → draw on a U-100 syringe (100, 50, or 30 IU). Long-press any result to copy it to your clipboard. Works for any peptide — semaglutide, retatrutide, BPC-157, your stack of three. The math doesn't care.
90+ peptide entries with primary-source citations — PubMed DOIs, ClinicalTrials.gov NCTs, FDA labels. Reconstitution tables are calculator-rendered, never hand-typed. Open the reconstitution calculator straight from the library to run the math yourself.
Pro turns the calculator into a tracker: a dose log and history, a body map for site rotation, a journal, a weekly recap, vial inventory with days of supply, and one-tap PDF export. It records what you logged — it never tells you what to take.
Why we exist
Most peptide apps were built by people who don't actually run peptides. So they ship glossy dashboards, push affiliate links to sketchy vendors, and dress up basic math with AI buzzwords.
Vialwise is built by someone who runs them — and got tired of doing reconstitution math in a Notes app while squinting at a u-100 syringe at 6am.
No vendor partnerships. No hidden upsells. No medical claims. Just a calculator that's right, tracking that's honest, and a price that doesn't insult you.

The advanced suite: dose history, body map, journal, vial inventory, PDF export, the blend/titration/cost calculators, shared-vial, and the live half-life view. One payment, no subscription.
Founder price — locked in now. It goes up as more features ship.
Coming to Pro
Pro is a one-time purchase, unlocked inside the app. Everyone gets unlimited protocols, the full calculator, and the peptide library, free, today.
What we don’t do
We don’t say peptides ‘optimize’ or ‘heal’ or ‘improve’ anything. That’s a doctor’s job, not an app’s.
We will never partner with a peptide source for affiliate fees. The day we do, we deserve to be uninstalled.
We use AI for one thing: a friendly weekly recap (opt-in). Not a personality, not a coach, not a buzzword.
Health data stays on your device. Nothing aggregated for sale. Nothing sold to insurers. Period.
If a feature doesn’t make the calculator more useful or your protocol easier to run, it doesn’t ship.
Pro is one-time, not a subscription. Buy it once and keep it — no recurring billing, nothing to cancel, no ‘are you sure?’ theater.
Questions
No. Vialwise is a calculator and a tracker. It doesn't tell you which peptide to take, what dose to run, or whether peptides are right for you. Talk to a doctor for that. We help you do the math correctly once you've already decided.
No, and we never will. There's a real conflict of interest in being both 'the app that tells you you need more' and 'the app that gets paid when you buy more.' We picked a side.
Any peptide you can reconstitute. Semaglutide, tirzepatide, BPC-157, TB-500, ipamorelin, CJC-1295, retatrutide, MOTS-c — the calculator doesn't care about brand names. It cares about mg per vial, mL of BAC water, and dose target.
Yes. Everything you enter — peptides, doses, protocols, and your dose log — stays on your device. The app collects no personal data and transmits nothing to a server; Apple's App Privacy label reads "Data Not Collected," and the app ships no analytics, ads, or trackers on either platform. We never see your data.
Yes. VialWise is on the App Store for iPhone and on Google Play for Android. The forward and reverse calculator and 90+ cited peptides are free; Pro adds the full tracking suite as a one-time purchase.
Free gives you unlimited saved protocols, basic dose logging, the full forward and reverse calculator, the complete 90+ cited library, basic dose reminders, and the single-dose half-life chart. Pro is a one-time $44.99 purchase, not a subscription, that adds the advanced tracking suite (dose history and back-logging, body map for site rotation, live doses-remaining and vial inventory, the journal, PDF export, and weekly recap), the advanced calculators (blend, titration, and cost-per-dose), shared-vial support, the live half-life view, and advanced catch-up and expiry reminders. Free stays free, forever, even after you buy Pro.
No — one-time. Pro is a single $44.99 purchase in the app (App Store or Google Play). You buy it once and keep it: no recurring billing, no auto-renew, nothing to cancel.
Yes. VialWise is now available on Google Play, and on the App Store for iPhone. Because the app is built on React Native, both platforms run the same calculator and cited library.
