A peptide reconstitution calculator inside your dose tracker.
Enter the values from your own vial and plan, and Peptide Protocol converts concentration and target amount into volume and the matching mark on U-100, U-50 or U-30 insulin syringes. The result can be saved with the protocol instead of recalculated every time.
Download Peptide Protocol — FreeWhat is peptide reconstitution calculator app?
A peptide reconstitution calculator converts three user-provided values: vial amount, diluent volume and target dose. Peptide Protocol calculates concentration, draw volume, syringe units and estimated doses per vial, then keeps those values beside the schedule and inventory on iPhone.
What Peptide Protocol tracks
| Inputs | Use the vial mass, liquid volume and target amount you already have; the app does not select them for you. |
|---|---|
| Outputs | See concentration, mL to draw, syringe units and an estimated number of doses in the vial. |
| Syringe support | Switch between U-100, U-50, U-30 and standard mL displays without re-entering the calculation. |
| Protocol context | Store the arithmetic with the routine so logging, inventory and future reminders use one consistent setup. |
| Share card | Export a clean calculation summary containing the inputs and mathematical result for review. |

How to use it
- 1
Enter vial amount
Copy the mass printed on the container, using the same unit shown by the product or pharmacy.
- 2
Enter liquid volume
Record the amount of diluent actually added; approved pens and ready-to-use solutions do not require this workflow.
- 3
Enter your target dose
Use the amount already provided by your clinician or protocol; Peptide Protocol never chooses it.
- 4
Read and verify the result
Review concentration, mL and syringe units together before saving or sharing the calculation.

Peptide reconstitution calculator app — common questions
Which insulin syringe sizes does the calculator support?
Peptide Protocol supports U-100, U-50 and U-30 insulin-syringe scales, plus mL. Changing the display scale recalculates the mark from the same draw volume; it does not change the amount of compound.
Does the app tell me how much peptide to take?
No. You provide the vial amount, liquid volume and target dose. Peptide Protocol performs arithmetic on those entries but does not recommend, prescribe or adjust any medication or research-compound dose.
Is there a free browser version of the calculator?
Yes. The companion site at peptide-calc.app offers a free reconstitution calculator with shareable URL inputs and no signup. The iPhone app adds schedules, dose history, site rotation and inventory around the same type of arithmetic.
