Why storage temperature matters

You protect your factor because your factor protects you. If a treatment becomes too hot or too cold, it could affect how it works. The high temperature stability of Esperoct® (from 36°F to 104°F) keeps you more prepared for life’s adventures or unexpected moments.

This gives you more flexibility with how you transport your factor when you leave the house or go on vacation.
