Peptide calculator
Step through your vial setup, target dose, and schedule to see syringe marks, approximate doses per vial, and how long a vial might last at a given frequency. For research and educational use only.
Step 1 · Vial
Tell the calculator how much powder is in the vial and how much liquid it's mixed with after reconstitution.
Step 2 · Dose & schedule
Choose a target dose and how often you plan to use it. This drives the syringe line and the "how long will this vial last" estimate.
How to use this calculator
This tool turns the numbers on your vial and syringe into a simple "draw to here" reference, plus a rough sense of how many doses a vial might cover. Hover labels and values to see quick explanations.
- Step 1: Match the vial label (amount and reconstitution volume).
- Step 2: Enter a target dose, how often you plan to research it, and your syringe size/scale.
- Step 3: Read off the syringe units, the approximate vial duration, and use the visuals as a sanity check.
Numbers here are approximate and don't incorporate stability, losses, or any clinical decision-making. Always cross-check against source material and professional guidance.
Step 3 · Dose, syringe mark & vial duration
- Concentration: 2.500 mg/mL (2500 mcg/mL)
- Volume for dose: 0.100 mL
- Syringe units to draw: 10.0 (on a 100-unit scale)
- Approx. doses per vial: 20.0
- Vial duration at 3 /week: 6.7 weeks (47 days)
- Quick duration bands:~6.7 weeks~1.7 months
These calculations are simplified and assume even distribution after reconstitution. They do not account for stability, injection technique, or any clinical decision-making. Always cross-check against primary research and professional guidance.
