free research tools
Peptide calculators that just work.
Reconstitution, unit conversion and half-life decay — accurate, instant, and free. Built for reference and education, never for dosing advice.
Calculators
🧪
Reconstitution Calculator
Any peptide → concentration and units to draw, on a live syringe.
🔬
BPC-157 Calculator
BPC-157 vial + water + dose → exact insulin-syringe units.
🧬
TB-500 Calculator
Reconstitute TB-500 and see the draw on a live syringe.
💧
Semaglutide Units
Convert a reconstituted vial to syringe units (conversion only).
💧
Tirzepatide Units
Convert a reconstituted vial to syringe units (conversion only).
🔁
mg / mcg / IU Converter
Convert between milligrams, micrograms and international units.
📉
Half-Life Decay
Estimate how much peptide remains over time from its half-life.
Track your protocols in the Peptide Lab app
