Several embodiments include methods of storing injectable substances, inhalers, pharmaceuticals, or drugs. In some embodiments, the storage system includes an outer case; a vacuum flask located inside the outer case; and/or a thermal bank located inside the vacuum flask. Some embodiments include isolating the injectable substance from fluids located outside of the injection device.<br>In some embodiments, the first phase change material can have a first melting temperature greater than 40 degrees Fahrenheit and less than 74 degrees Fahrenheit. The second phase change material can have a second melting temperature greater than 74 degrees Fahrenheit and less than 100 degrees Fahrenheit. The first melting temperature can be at least four degrees Fahrenheit less than the second melting temperature. For example, 74 degrees Fahrenheit can be approximately equal to a typical room temperature (although room temperatures commonly range from 67 degrees Fahrenheit to 80 degrees Fahrenheit in rooms having temperature controlled environments enabled by heating and/or air conditioning).
