Good rule of thumb in my area these days, as follows, if the shard is just obviously large, think this looks bigger than back when crank first turned to crystal in most places years ago, if your answer is yes, continue, next can you rather easily crumble crush etc , between ya finger and thumb with minimal, sometimes little to no pressure? then 9 out of 10 times what you have is shit. Most likely ISO, if your IV'ing it, the initial rush, can quite often feel rather nice (stimulant-ish rush in nature) that's all ya getting though & its over quickly, now you get to enjoy the effects of having IV'd a non-energy producing, non-euphoric, but completely full of all the shitty effects of a bad stimulant on your cardiovascular system, for while to be honest. Recommended that if this seems to describe some of yall's experiences, now would be the right time to start benzodiazepine dosages of any sort, its your safest way back.
MSM can be quiet easily removed for the older more "educated in the arts" user. Remember that shit acetone ya'll probably bought from a hardware store has H2O in it and some Epsom salt will be needed to help pull the moisture out, most already know this and if ya wonder how long to leave it before ya acetone is as good as ya need, well you (meaning, anyone in general) obviously have never done this AT ALL. Here's a tip, leave it alone for days, just trust me. (I realize there's a much quicker way).
This however is for the "newbie cleaner" I'm dumbing it down, of course assuming most will already have been up a few days when they get on this site and start wondering why the shit they have doesn't seem to be as good as it was on day one, never realizing until much (more often...MUCH) later in their drug use careers that you can not keep doing it day in & out. You can, we all did, but not eating or sleeping, maybe drinking water, probably energy drinks or some shit, they dont realize you can NEVER expect anything to provide the day one enjoyment no matter how much you waste trying.
It's during this time they'll find this site, and think, "That's what's up, I found the answer...lol..I just gotta clean it. Despite not realizing it was obviously good enough to keep ya up for days giving ya body no food or sleep, and that's when they'll take that bag sitting beside them, head to the store....wait for it...that's right, and lose all their junk. (I'm not laughing...much, lol, I just remember way back how all of us sort of progress more or less the same way through all the various degrees of usage...until we either die, learn the best ways of how to care for yourself correctly if you are going to do it, or become completely shot out to the point you can no longer care for yourself (that outcome sadly can be combined with being behind bars for a long time, mainly because you never learn that sometimes you just don't need to be out in public after being in the woods for 8 nights, then walking in Walmart at 3am with ya flashlight LED still strapped to ya head, standing there looking at all the cans of spray paint...
Crazy that a security or law enforcement officer would ever want walk up and see what on god's good earth is this delightful young person up to? All this is just to drive home the point, stay where it's cool, once your no longer cool, and while i realize in their early days of usage this invisible line is basically non existent, most of us that's been around know pretty much exactly when that point is, yes we can all still slip, but being older with no probation or warrants or cases hanging over you and a good job, maybe ya woman, etc, we don't even want to be put in those (while funny to talk about) but stupid ass unnecessary situations AT ALL ANYMORE...Peace to all of you out there just trying to enjoy the day...its all ya got.
