Dose peptides safely and actually understand them. Precise reconstitution math, a real harm-reduction safety hub, and plain-English guides to 40+ compounds.
Vialo is built for people who take peptides seriously and need to get it right. It pairs a precise dosing calculator with a real safety and education library, so you know both the exact amount to draw and the reasoning behind it.
SAFETY FIRST, NOT AS AN AFTERTHOUGHT
The Safety Hub covers what actually keeps you safe: sterile handling and infection control, injection technique, rotating your sites, storage and stability, and how to recognize a bad product. You get clear guidance on which side effects are normal and which ones mean you should stop and seek care right away.
LEARN EVERY COMPOUND
Evidence-based, plain-English breakdowns of how each peptide works, typical dosing ranges, and how to handle it. More than 40 peptides are covered, including blends like GLOW and KLOW. No forum guesswork, no hype.
ACCURATE RECONSTITUTION AND DOSING
Enter your vial strength, the bacteriostatic water you added, and your target dose. Vialo shows the exact number of units to draw on an insulin syringe, with a clear "draw to this mark" indicator, plus concentration, doses per vial, and a warning when a dose is too large or too small to measure accurately. Tap any result to see how it was calculated.
PROTOCOLS AND REMINDERS
Save any dose as a protocol, set how often you take it, and check it off each day. Optional reminders stay on your device and keep you consistent without the clutter.
FIND THE RESEARCH
Search PubMed, Google Scholar, ClinicalTrials.gov, and preprint servers for studies on any peptide, without leaving the app.
PRIVATE BY DEFAULT
No account, no login, no tracking. Everything you enter stays on your device.
Vialo is an educational and harm-reduction reference tool. It is not medical advice and does not replace a licensed healthcare professional. Always verify your calculations and use sterile technique.
Honestly this app has been such a game changer for me. As someone just getting started, I was constantly double checking (and sometimes second guessing) myself trying to keep track of dosing across a handful of different peptides. It’s easy to lose track of what you took, when and how much. Especially when you’re juggling more than one at a time.This app takes all that mental struggle and worry out of it. Everything’s laid out clearly so I always know exactly where I’m at, and I don’t have that nagging “wait, did I already take this?” feeling anymore. It’s made me feel so much more confident and consistent with my routine.If you’re a beginner like me and feel overwhelmed trying to keep everything straight, I can’t recommend this enough!

You can feel confident in what products to use with instant access to proper research, and stay on track with safe dosage. Ui is very responsive and smooth.
Simple and straightforward
Beccccccck
This simplified such a confusing process for me. I have been using peptides for just under a year and have notes in my phone to help me track my symptoms or side effects (as applicable) and to also help me remember how much of each I take and when. This was suggested to me by a friend and it’s worth the $4… I don’t have to sift through my notes apps. I can track when I need to throw things away vs use them and it taught me about why I should stop injecting into the same spot every time (oops). I highly recommend for the info it teaches you alone - the tracking on top of that is a huge plus for me.
