Essential guides
New to peptides? These cover the fundamentals every researcher needs.
Beginner's guide to peptides
What peptides are, how they work, the main categories, handling and how to use this site.
How to reconstitute peptides
The reconstitution process step by step, bac water, concentration math and worked examples.
Syringe & measurement guide
How to read U-100, U-50 and U-20 syringes. IU vs mg vs mcg vs syringe units explained.
From vial to dose, in three steps
The workflow every reference here follows, and what the calculator below handles for you.
1. Reconstitute
Add bacteriostatic water to the freeze dried vial to make a solution.
2. Set the concentration
Water volume fixes the strength. 10 mg in 2 mL is 5 mg per mL.
3. Read the numbers
The calculator converts an amount to its concentration and equivalent volume.
Reconstitution calculator
Enter a vial size, a water amount and a target amount. Read back the concentration and the equivalent volume in mL and U-100 units.
On a U-100 syringe, 100 units is 1 mL. This is reconstitution math for research reference only. It is not a dosing recommendation or instructions for measuring or administering any compound.
