Trying to figure out at home how many units is 250 mcg, how to mix peptides correctly, or how to calculate your exact dose in mL? You’re not alone — peptide dosing can be confusing, especially when you’re preparing injections yourself. Our Peptide Reconstitution Calculator helps you quickly convert mg to mcg, calculate peptide concentration per mL, and determine insulin syringe units based on your vial strength and dilution. Whether you’re using Sermorelin, Tesamorelin, CJC-1295, Ipamorelin, GLOW Mix, or NAD+, this tool makes at-home peptide dosing simpler, clearer, and more accurate in seconds.

Common question patients ask when starting peptide therapy:
The number of units for 250 mcg depends on your peptide concentration after mixing.
Always use a calculator or follow your provider’s instructions, as unit measurements change based on dilution.
Below are common examples based on typical reconstitution ratios. Actual dosing may vary depending on your prescription.
| Vial Strength | Diluent (mL) | Dose | Units (U-100) |
|---|---|---|---|
| 5 mg | 2 mL | 250 mcg | 10 units |
| 5 mg | 3 mL | 250 mcg | 15 units |
| 5 mg | 5 mL | 250 mcg | 25 units |
| 10 mg | 2 mL | 500 mcg | 10 units |
| 10 mg | 5 mL | 500 mcg | 25 units |
Note: These are general examples. Always follow your provider’s instructions and prescription label.
🟢 Peptide dosing depends on both the amount in the vial and the total diluent added.
🟢 This calculator estimates concentration, dose volume in mL, syringe measurements, and estimated doses per vial.
🟢 The same peptide dose can equal different syringe amounts if the vial strength or reconstitution amount changes.
🟢 Always verify the product label and provider instructions before injecting.
Follow these simple steps to calculate your peptide dose, syringe units, and reconstitution ratio accurately.
Choose the peptide you are using, such as Tesamorelin, CJC-1295, Ipamorelin, GLOW Mix, or NAD+. Each option adjusts default dosing ranges and units.
Input the total amount of peptide in the vial. This tells the calculator how much active compound is available before reconstitution.
Enter how many mL of bacteriostatic water or other diluent you added. This determines the final concentration of the solution.
Input your target dose per injection. The calculator converts this into volume and syringe measurement.
Select insulin, tuberculin, or standard syringe. The calculator adjusts the output based on the syringe style you use.
Check the estimated concentration, mL per dose, syringe measurement, and doses per vial. This helps confirm whether your settings look correct before proceeding.
Always compare the calculator result with your prescription label, pharmacy instructions, and provider guidance. This tool is for educational use only.
