Horse steroid shit? You mean MSM? First of all, it's not a steroid. It's a growth hormone to help them with making stronger healthier joints. Secondly, it's not just for horses. It's also used heavily in traditional chinese or japanese cooking(I'm not sure which, maybe both), as well as many other animals.
Another thing, the reason it tastes nasty in the pipe. Is because it's still dirty.
Oh yeah about that burning off any impurities or cut or whatever you said its called cutting or something thats not realistic G.
I never said it would burn off impurites. I said that's what I was told. I know it doesn't burn anything off. Here, this is a direct quote of what I said. 'Supposedly ment to burn off cuts and impurities, however this is bullshit. Most cuts and practically all impurities melt right down and recrystalize in with the meth. Burning off while you smoke, and going into your lungs. Don't worry, this stuff is good for you. It'll grow some hair on your chest. Although "cutting" doesn't burn off any impurities or cuts, it does seem to make the bowl last longer.'
Oh, and don't call me G... ok dawg?
One last thing, and I'm not trying to be a prick here... but try using paragraphs next time. It makes things a hell of a lot easier to read.
EDIT- Fixed the bold tags.
