Reconstitution Calculator
Enter your vial size, the volume of bacteriostatic water used, and your target dose. The calculator returns the exact draw on a 100-unit insulin syringe, the resulting concentration, and how many doses a single vial yields.
Units are based on a standard 1 ml (100 unit) insulin syringe. Figures are for in-vitro laboratory reference only — Apex Peps does not provide medical or dosing advice.
How reconstitution works
Lyophilised peptide is a dry powder. Adding bacteriostatic water dissolves it into a solution with a known concentration in mg per ml. Less water means a more concentrated solution and a smaller draw; more water means an easier, more precise measurement on the syringe. Direct the stream against the inner glass wall rather than onto the powder, and swirl — never shake.
Storage after mixing
Keep reconstituted vials refrigerated at 2–8 °C and protected from light. Unreconstituted lyophilised powder is stable long term at −20 °C. Every Apex Peps batch ships with HPLC purity and mass-spectrometry identity data.
