^^^How many pills/milligrams do you shoot at once? What is it compared to as far as street H, like how many bags would equal 60mgs of MS Contin, etc.?
I would shoot a 60mg when my tolerance was reasonably low, so maybe you should start off from there (I'm assuming you shoot H, so aren't new to IV opiates) and just work your way up. Since I live in Australia, our "bags" would be completely different... but you could work it out on the weight/purity of your bags, 10mg diamorphine (heroin) = 30mg morphine.
After it's filtered, does it really boil down thin or is it thick and syrupy? I would think the binders are attached to the actual morphine and not just on the outside, making it more difficult.
First of all, don't heat/boil it... it may look like more of the pill is dissolving (well it is), but morphine is actually being "trapped" inside the wax (Flexi knows a lot about this sort of stuff). It comes out quite thin, since you have to use a fair amount of water (1.5 - 2ml per pill, makes micron filtering more effecient).
Micron filters are no-brainers to use... just dissolve your pill in the spoon, attach a needle (I use 3ml BD's with 26G tips) and draw up through a cotton filter (I use rollie cigarette filters)...
Detach the needle, attach a micron filter to the barrel, attach another needle onto the micron filter... expell the solution (already part filtered through cotton) through the micron filter into the back of a fresh syringe and shoot away.
I've written more detail explanations, but like you say, it's hard to find them
though using micron filters are extremely simple... you just need 2 piece syringes (3ml barrels at least) so you can attach them... also you wet the micron filter before you use it, so you don't lose as much water in it.
Safe shooting :D If you got any specific questions, just ask away.
