Peptide Calculator - Dose Tool

Dose Tool is a peptide dosage calculator and dose log in one simple app. Enter the amount in your vial, the bacteriostatic water you mixed in and the dose you want. It shows the exact mark to draw to on your insulin syringe, then keeps a record of every dose and every vial.

PEPTIDE DOSAGE CALCULATOR
• Syringe units for any vial, water volume and dose
• Vial in mg or mcg, water in ml or in syringe units, dose in mcg or mg
• 0.3 ml, 0.5 ml and 1 ml syringes (30, 50 and 100 units), U-100 and U-40 scales
• A drawn syringe shows exactly where to stop
• Concentration (mg/ml), injection volume, doses per vial and cost per dose
• Warns when a dose will not fit your syringe, and catches the classic mg/mcg mix-up

PEPTIDE RECONSTITUTION CALCULATOR
• Not sure how much water to add? It suggests a water volume that lands your dose on a round, easy-to-read mark
• Change the water and the units update straight away

The maths is the same as the free peptide dose calculator on peptidedosetool.com, checked against hand-worked examples.

DOSE LOG IN TWO TAPS
• Log a dose straight from the calculator, or repeat a recent one with one tap
• Compound, amount, syringe units, injection site, date, time and a note
• A calendar of what you actually did, day by day
• Injection site history: every site with the last time you used it, longest ago first
• Export your whole log as a CSV file

VIAL TRACKER
• Save a vial when you mix it: amount, water, concentration and mixed date
• See roughly how much is left, from the doses you logged
• See how many days it has been mixed, with your own "use within" day count

SIMPLE AND PRIVATE
• Works offline
• No account and no sign-up
• Your log stays on your phone — it is never uploaded to us
• No ads and no tracking

WHAT IT IS NOT
Dose Tool is arithmetic on the numbers you enter and a record of what you logged. It never suggests what or how much to take. It is not medical advice and not a medical device, and it does not diagnose, treat, cure or prevent any condition. Check every result against your vial and your syringe.

SUBSCRIPTION
Dose Tool requires a subscription, with a free trial on the yearly plan. Prices are shown in the app before you subscribe. Subscriptions renew automatically until cancelled; cancel any time in Google Play → Subscriptions. The peptide calculator on peptidedosetool.com stays free.
