Storing - Mephedrone Degradation

[jaredfelix]

Hello everyone, this is my first post. I have been reading alot of information on mephedrone on this site and I think I am starting to like this forum more then hipforums or even bluelight, both of which I am an active user.
I just have a couple of questions which i hope can be answered, but if not i understand, it is a new substance, well relatively anyway.

Ok, SWIM plans on making an order of 25 grams of mephedrone and i am curious as to how long it will last not being frozen, just room temperature, and out of the sunlight. Will potency decease significantly at all? How long will it keep its potency? What do you recommend?

And for a starting dose, it will be my first time with this substance, I plan on taking it orally and am curious to a good, feel good, dose.

--Thank you all
