How many units is that, exactly?
Every protocol starts with the same awkward arithmetic: milligrams in the vial, millilitres of bacteriostatic water, micrograms per dose. VialPal does that maths, shows its working, and remembers what you actually took.

Vial strength, bacteriostatic water, target dose. Out comes the number of units to draw — plus the concentration and volume, so you can check it against your own arithmetic. Free, no sign-up.

Keep this vial. VialPal holds the concentration, counts down the doses left in it, and logs the ones you actually took.
VialPal does the arithmetic — it does not tell you what to take. Dose decisions belong between you and a qualified clinician.
More than just a reminder.
Most apps just tell you when to inject. VialPal handles the mixing maths, tracks what is left in the vial, and shows how the compound actually behaves in your body.
Reconstitution Calculator
Enter vial strength, diluent volume and target dose; get units, concentration and volume. When a dose is too small to measure or too big for the syringe, VialPal says so instead of showing a number you can't act on.
23 Peptides Supported
Healing, growth hormone, metabolic, immune, cognitive, longevity and sexual health compounds — each with half-life, vial sizes, storage and regulatory status. Custom compounds supported.
Concentration Over Time
For peptides with a characterised half-life, see estimated levels between doses. Half-lives here run from twenty minutes to a week, which changes what a sensible schedule looks like.
Vial Inventory & Expiry
Track which vials are open, when each was reconstituted and how many doses remain. Reconstituted peptides have a shelf life — VialPal counts it down so you're not guessing at the back of the fridge.
Smart Reminders
Visual countdown rings for your next injection. Never miss a dose or double-dose by accident.
Side Effect Monitoring
Log injection-site reactions, fatigue, headaches or anything else. Identify patterns over time to discuss with a clinician.
Cycles, Stacks & Schedules
Most protocols run on and off across weeks and combine several compounds. Set a cycle once and VialPal tracks where you are in it.
Injection Site Rotation
Interactive body map to log injection sites and get rotation suggestions, so you're not repeatedly hitting the same spot.
23 peptides, with the status stated plainly.
Half-life, typical vial sizes, storage, and whether a compound is actually approved for human use — which, for most of this list, it is not.
Science made simple.
Mix your vial
Tell VialPal the vial strength and how much bacteriostatic water you added. It works out the concentration and exactly how many units each dose is.
Log every dose
Takes 10 seconds. Record the injection, the site, and anything you noticed afterwards — sleep, soreness, appetite.
Discover insights
See how your body responds as concentration rises and falls, how much is left in the vial, and where you are in the cycle.
