RE: powder steroids snorted?
Also if I could add to what my bro Power said there...
The idea makes no sense really.
Absorption of steroids through the nasal membranes is poor.
Steroids are fat soluble, not water soluble. Things that pass through the nasal membranes easily are things that are water soluble (coke, etc). Fat soluble stuff just doesn't get absorbed well.
So not only is snorting steroids a bad idea with regards the health of your nose, it's also not an effective way to get much of the steroid into your bloodstream.
The only results you would get from this would be the drip, going down into your stomach and being absorbed that way. So eat the powders if you really must, it will give the same results as snorting, but with a little less pain on the nose.
