Dose - I have a few questions

[Ronin]

Swim is used to having a 'friend' providing her with speed, preparing it for injection, and helping her shoot up; basically taking care of everything for her. The thing is that her 'friend' is going clean now, and swim, despite having witnessed it multiple times, don't know much about for example dosage, quality, storing etc. She is used to everything being taken care of, so she never really bothered to learn much about it tbh. Swim can't ask her 'friend' for advice on the matter since she doesn't know where the hell he's gone (he left town or something), and all in all she never really trusted him much either. Swim's 'friend' has always been her only inside contact when it comes to drugs. Swim prefers to keep a low profile when it comes to this, so she doesn't want just anyone to know she's into it.


Swim thinks the speed where she lives is very dirty and hasn't had any good stuff for a long time, so this is all swim can get these days. How does swim estimate the dose with stuff of poor quality?
Obviously, swim's guessing that she'll have to use more mg of this stuff to get the high she's after compared to if what she had was of "good"/normal quality. Is there a simple rule or tip for how much more of the low quality swim must use to achieve a somewhat similar effect as when using good quality?


Would it have any effect if swim filters it twice, will it make it any 'cleaner'/'purer' at all?


What would be considered a 'normal', low, and high dose (mg) amongst users? And is there a vast difference between the amount one would use when snorting as opposed to when one injects, or is it pretty much the same dose?


For how long will speed dissolved in water stay good? As in how long can you store an already prepared shot before it affects the quality of the shot?


Any advice on how speed of good quality should look? Colour, smell, consistency? Anything that is typical for low quality then? Anything swim should avoid?


Swim's been thinking a bit lately about whether there's a certain tactic swim ought to follow when swim is going on a speed binge that will maximize the effect? Should swim start with a big shot, then decrease the dose for each shot following it? Should she use the same dose with every shot? Or start with a small one and work herself up to a big one? Or does it really matter? And how long do you guys usually wait before taking a new shot? What let's you know that now is the time for å new hit? Do you get the new one before the last high is over?


Is it dangerous for swim to inject soon after injecting if the first hit didn't give swim much effect? What could the effects be?

Sorry for making it such a long post. But I would really appreciate your advice and opinions.
