Peptide Dosage Calculator
Use this peptide dosage calculator when concentration is already known. Enter mg/ml and the desired peptide dose in mcg to get dose volume in ml, insulin syringe units, and the mcg value per unit without redoing the conversion manually.
Known concentration input
Designed for cases where the vial is already mixed and mg/ml is confirmed.
Final draw amount
Converts a target mcg dose directly into ml volume and U-100 syringe units.
Transparent conversions
Shows the same assumptions used across the site so users can verify the numbers quickly.
Reference scenario
2.5 mg/ml concentration + 250 mcg target dose
Dose (mg)
0.25 mg
Dose volume
0.10 ml
Syringe units
10 units
mcg per unit
25 mcg
Use the known mix concentration
Target amount for one administration
Primary output
10 units
Draw this amount on a U-100 insulin syringe.

25 mcg
Best for known concentration
This mode is useful when the vial is already mixed and you only need to convert a target mcg dose into ml volume and syringe units.
Enter concentration
Use the known vial concentration in mg/ml after reconstitution or from an existing label.
Set target dose
Enter the desired peptide dose in mcg and the calculator converts it into mg and ml.
Read the units
Use the final output to translate ml volume into U-100 syringe units for easier interpretation.
Dose conversion
desired_dose_mcg / 1000
Dose volume
dose_mg / concentration_mg_per_ml
Insulin syringe units
volume_ml * 100
mcg per unit
(concentration_mg_per_ml * 1000) / 100
Need concentration first?
If you do not yet know mg/ml, use the reconstitution calculator first. This page assumes concentration is already established.
Dose in mg
Useful when users think in mcg but need to understand the equivalent milligram amount.
Dose volume in ml
Shows the liquid volume required to reach the desired peptide dose at the known concentration.
Insulin syringe units
Converts the final volume into U-100 units so the draw amount is easier to read on a syringe.
mcg per unit
Helpful for quick repeat dosing because it shows how much peptide each syringe unit represents.
Peptide Reconstitution Calculator
Use this first if you still need to derive concentration from vial strength and water volume.
