Refrigerate Powder/Gear

Is it better to refrigerate or keep in a cool,dry location?
I have both brewed gear and raw powder should either or both be put in the fridge?
I’ve read from some pharmaceutical sites that refrigerating powder is a MUST.
Any help will be appreciated, Tim

No reason not to refrigerate powder. T and T esters are very stable in any case. But if there were some bacterial in the powder, cold or freezing would have some effects.

Don’t chill esters in oil as this makes loading and shooting sssslllllooooowwwww. A proper product will have around 1% benzyl alcohol to prevent bacterial problems.
