How Long Can I Store Powders?

[nydj66]

What's the best way to store raw hormone powders like test enanthate? Refrigerator?

And, how long can I expect them to keep their potency?

Speaking in general from handling medication and chemicals..they should be stored in a cool dry, non reactive container..free from heat, light, and moisture. and airtight as much as possible.

I have no evidence to base my answer on how long test esters will stay good for

i heard after one year they start to lose potency but will still be effective

This is an excellent question and I have been looking for a solid, scientific answer yet I am still looking. I do know it depends on the specific substance but I do not know specific times / potency % decrease over time etc.

There has to be a chemistry major on the board...
