Reconstitution Tool

Peptide Calculator

Calculate peptide syringe dosing and reconstitution mixtures.

100% Free & Local
STEP 01

Input Vial Milligrams

Enter the total mass of peptide freeze-dried powder inside your vial (typically 2mg, 5mg, or 10mg).

STEP 02

Sterile Water Volume

Input the amount of bacteriostatic or sterile water (in mL) used to dissolve the peptide.

STEP 03

Syringe Scale

Choose your syringe capacity standard (typically a 100-unit U-100 or 50-unit insulin syringe).

STEP 04

Set Target Dose

Enter your desired dose in micrograms (mcg) and click Calculate to obtain drawing tick marks.

Help

Common Questions Answered

Support
Q1 What is peptide reconstitution?
Reconstitution is the process of adding sterile water to freeze-dried peptide powder to dissolve it back into a liquid state suitable for injection.
Q2 What is the conversion ratio between mg and mcg?
One milligram (mg) contains exactly 1,000 micrograms (mcg). E.g. a 5mg vial contains 5,000 mcg.
Q3 How many mL are in a 100-unit insulin syringe?
A standard U-100 insulin syringe holds exactly 1.0 mL of liquid, meaning each unit line represents 0.01 mL.
Q4 Why does water volume affect drawing units?
Adding more water dilutes the mixture, requiring you to draw more units of volume to achieve the same target microgram dose.
Q5 What is bacteriostatic water?
It is sterile water containing 0.9% benzyl alcohol, which inhibits bacterial growth, allowing reconstituted peptide vials to be stored safely in the refrigerator.
