Peptide Reconstitution Chart
Enter your vial size and target dose to generate concentration and syringe-unit tables across common bacteriostatic water volumes. Your entered volume is highlighted, and units that exceed your syringe are flagged.
All insulin syringes read 100 units per mL — the size just sets the capacity. If a draw exceeds it, split the dose or add more water.

What this chart is
Reconstitution means dissolving lyophilized (freeze-dried) peptide powder into a liquid you can measure and inject. Bacteriostatic water is the usual diluent — it contains a small amount of benzyl alcohol that limits bacterial growth so a mixed vial keeps for weeks in the fridge.
How to read it
More water means a lower concentration and a larger, easier-to-measure draw. Less water means a smaller draw but tighter tolerances. Pick a volume where your target dose lands on a clean, readable number of units within your syringe’s capacity.
