Injectable Peptide Dosage Calculator & Reconstitution Guide
Calculate peptide reconstitution volumes, mcg-to-mL syringe settings, and dosage schedules for research compounds.
Peptide Reconstitution and Syringe Dosage
Peptide reconstitution is the process of mixing sterile bacteriostatic water with lyophilized (freeze-dried) peptide powder to prepare it for laboratory research or clinical administration.
Calculating dosage requires understanding liquid volume, peptide weight in milligrams, and syringe markings (typically in units or milliliters). Precision is essential to avoid underdosing or overdosing compounds.
This calculator simplifies peptide math. Enter the vial size, amount of diluent water, and your target dose to find the exact syringe markings needed for your protocol.

Frequently Asked Questions
Q: What is peptide reconstitution?
It is the process of adding sterile bacteriostatic water to freeze-dried peptide powder to dissolve it into a liquid solution.
Q: How do you calculate units on a syringe?
This depends on the concentration. For example, a 10mg vial reconstituted with 2mL of water gives a concentration of 5mg/mL. A 500mcg dose would equal 10 units on a standard U-100 syringe.
