The raloxifene I ordered from RUI came as a powder in a container just like their others, only larger. It had directions for reconstitution, and stated that it needed to be refrigerated after reconstitution, and would keep for something like 60 days.
I'm not sure I'd feel 100% optimistic about the stuff you've got. The fact that it didn't have any information for you about it is a little disconcerting.
For the record, I had a lump a little bigger than a dime in diameter in my left nipple from test use without pushing an Aromatase inhibitor (AI) through the whole cycle (this is what you get for trying to take word-of-mouth advice rather than rely on science). I've been on rui's ralox for about 3 weeks now and that thing is fuckin' gone. Balls feel pretty much back to normal already, and sex drive is a little off-and-on, but I've got cialis/levitra/viagra for that
