Brassinolide shelf life

[shaggyballs]

Anyone know how long you can keep Brassinolide once it is mixed with a liquid?

I heard not long, unless you freeze it.

But I would like to know the shelf life once mixed accurately .

I heard the powder will last years kept cool and dry.

What do you plant to use the brass for veg or flower? Not sure on the shelf life but would definitely like to hear how you plant to use it and at what dose.
