Definitely tablets. For gear, it would most likely depend on solubility of the compound. The active may crash out (precipitate out), which may require some moderate heat to resolubilize. In my line of work, I have worked with some IV drugs that were kept at -20 C to compare to samples at 5 C and room temp. No issues were seen with frozen samples after they converted back to liquids. In fact, degradation was inihibited or rate severly limited. Although my experience is limited to specific compounds, if I had gear, I would throw it in freezer for long term storage. IF any drug recyrstallized, heat would most likely get the drug back into solution.
