Formula used

Potency after storage (%) = 100 × e^(−ln 2 × Days ÷ Class half-life)
Final potency (%) = Potency after storage × (1 − Freeze-thaw loss) ^ Cycles
Class half-lives range from 1.5 days (sensitive, room temperature) to 365 days (stable, frozen); freeze-thaw loss is 5%, 8% or 12% per cycle by class.
