Vialwise - Peptide Calculator

I built VialWise because I run my own peptide protocols and the existing trackers either skip the math, get the citations wrong, or push me toward stacks I didn't ask about. This is the app I wished I had.

Start with what's free, and stays free:

The calculator goes both directions. Forward: vial size + BAC water + target dose, and you get the exact draw on a U-100 syringe with a visual syringe display. Reverse: enter what's already in the syringe and back-calculate the dose. As far as I can tell, no other peptide tracker does the reverse-calc.

The library is 90+ researched peptide entries: GLP-1s, healing peptides, GH secretagogues, TRT-adjuncts, and blends. Every one is built from primary literature — PubMed papers, FDA filings, manufacturer documentation — and now leads with a plain-language read on what the research has actually studied it for, then the findings, with dose ranges, side effects, evidence-quality framing, half-life decay charts, cited storage notes, and citations you can click through to verify. No "best stacks" listicles. No vendor recs. No promises about how anything will make you feel.

Save as many protocols as you want, free — every compound and schedule kept separately, with basic dose logging, dose reminders, and a half-life decay view included. Keep an optional lot or batch number, a COA date, and a note on each vial's record, stored exactly as you enter them.

And the whole app comes in light or dark — follow your system, or pick a side in Settings.

Then there's Pro, a one-time unlock, where VialWise becomes the home base for the protocols you actually run:

- Full dose history with back-logging and editing, so you can fill in a dose you forgot to record.
- Tag where you administered on a body map, with sub-sites and rotation.
- A live "doses remaining in this vial" counter, spare-vial inventory, and shared-vial tracking for a vial split across people.
- Multi-dose accumulation charts over your own logged doses.
- Advanced calculators: cost per dose and vial, a custom titration or taper schedule, and the blend (multi-peptide) calculator you can save as one protocol.
- A weekly recap, a private journal, once/twice/three-times-a-day schedules, expiry and catch-up reminders, and one-tap PDF export of any protocol and its history.
- Optional Apple Health export for the weight you log, and private iCloud sync that keeps your protocols, log, and journal in step across your devices — end-to-end through your own iCloud, so VialWise never sees your data.

Pro is a one-time unlock. Buy it once and get every advanced feature, including the ones still shipping, with no subscription, ever. The calculator, the cited library, unlimited protocols, and half-life charts always stay free.

Everything you log stays on your device — and if you turn on sync, only in your own private iCloud.

A few things VialWise is not:

Not a medical device. Not medical advice. It doesn't recommend specific peptides, doses, or protocols — that's between you and whoever you work with on this.

Not a marketplace. You can't buy peptides through it. No vendor links. No affiliate codes. No commerce of any kind.

Not a data harvester. Your peptide and protocol data stays on your device, or syncs only through your own private iCloud. I don't sell it. I don't share it. I don't track you across the web. Full details: getvialwise.com/privacy

If you find a bug, a wrong citation, or a missing peptide, email [email protected]. I read everything and reply to most of it.
