^yeah please look at that thread.
Also, as others have said, you need a 'lure lock' syringe. It's a hypodermic with a detaching needle. I don't know what state you are in, and whether they can sell syringes without a prescription like here in NY, but basically, unless you order them online, ask the pharmacist for a 10ml syringe (they also come in 3mL and 5ml-I think). If you ar using them for IM,,as for a 1" tip (although that's what they usually give me unless I ask for smaller).
What you do is, detach the needle from the barrel and draw up a couple of mL of water. Then, screw the micron back on and push the water through it. Once you can't seem to get anymore water through the micron, take it off, and pull the plunger back so that its filled with 10mL (or however many mL the lure lock you get holds) and screw the micron once again on and push the air through the filter. The pressure will spray out the rest of the water stuck in the filter.
When it comes to microning actual drugs, I basically do the same thing.
1.Draw up the unfiltered dissolved drug into the lure lock.
2.screw the micron on to the barrel.
3.push slowly down on the plunger and get as much of the solution through the filter (and into a sterile cooer or ampoule).
4.take off the micron and draw back the plunger, filling it with air, and reconnect the micron.
5.Push the plunger down again, the pressure of the air will force the rest of your solution to be released.
(NOTE: when you do the last step (pushing the air through the micron) your drug MIT at first come out all foamy (or at least with East Coast Heroin it does.) Dont Freak out, the foam returns to a regular looking liquid with some stirring.
Anyways, I'm gonna close this thread. For any additional questions refer to the link my man Mr.Scagnattie posted above.
