Reconstitution

From a vial label to a syringe reading: the calculator, the cross-compound chart, the worked examples and the terminology guide. Concentration is vial amount divided by water volume; everything on this page is that division and its consequences. Research use only.

Tools

Calculator
Peptide Reconstitution Calculator
Vial amount and water volume in; mg/mL, micrograms per unit and the U-100 syringe reading out — with the math shown.
Calculator
Peptide Blend Calculator
For pre-mixed vials: each component worked from its own split, because a blend's total cannot be used for any single peptide.
Tool
Peptide Tracker
Records vial size, water volume and units drawn so every entry is reconstructable; weekly grid and calendar export. Nothing uploaded.

Reference pages

Peptide Reconstitution Chart
What every common vial size gives at 1, 2 and 3 mL, the reverse lookup from concentration to units, and the syringe scales.
Peptide Reconstitution Calculator Guide
The plain-English companion to the calculator's fields, the unit wording and the mistakes the arithmetic is prone to.
Reconstitution Math Examples
Worked examples from label to syringe, step by step, in the same arithmetic the calculators run.
How the math works
The three formulas every page here uses, the constants they rest on, and the sources for them.
