Built by someone who actually runs peptides. Full library, free. Pro for multiple active protocols.
Research and educational only
Today
Look up a peptide, or calculate a dose.
What it does
The calculator is the hero. The library is the source of truth. The today view is the only place you check in. That’s v1.
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.
64 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.
Today's protocols at a glance. Tap the circle to mark today's dose checked. “All set for today” when you've cleared the list. Clean, simple, and exactly what you need to stay consistent.
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.

Pro unlocks unlimited protocols. Everyone gets full access to the library. No trials that auto-bill, no surprise tier changes, no "7-day money back" runaround.
The calculator, plus tracking for your first peptide.
Unlimited peptides, reminders, and the full toolkit.
Pro is coming soon. Everyone gets 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, post-launch). 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.
One subscription tier. Cancel in two taps. No friction, 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. v1 stores everything locally on your device. v2 (with Pro) syncs encrypted to your account. Health data from Apple Health stays on-device — we never see your raw weight, body fat, or biometrics. We're transparent about every byte.
Yes. VialWise v1 is now available on the App Store for iPhone — free, with the full reconstitution calculator and the peptide library. Android is on the way.
Free gives you the full calculator, the full library, and tracking for one protocol. Pro ($39.99/yr) unlocks unlimited protocols, scheduled reminders, inventory tracking, half-life decay charts, and Apple Health imports. Free stays free, forever, even after Pro launches.
Yes. iOS ships first, Android follows. The goal is to have both available close to launch — the app is built on React Native so the lift is smaller than a full rebuild.
