FIRST, make sure you haven't taken any other opiates in the last 24 hours(heroin,oxycodone,morphine,etc..) The each 1mg inected equals 4mg under the tounge. So really there is no need to do over 2mg at a time. You will notice if you do it this way you will have to redose after 12 hours or a little more. Use 60-70 units of water( I use kinda hot water, which is probly a no no, but it makes the strip dissolve in 5 mins or so, and kinda shake it around in the spoon, it helps it break down quicker) Get cotton draw up. If it looks cloudy draw up again..this has always been my method and I have never have any problems when i was doing it this way. Best to have a micron filter for sure, but a lot of us do not. Now when I say hot water I don't mean boilin or a lighter under the spoon(big no no). Just turn the hot part of the fosset on, and use the hot water from there, though it's probly better to use cold water, but I'm inpatient. After it dissovles just draw up through cotton once or twice, there ya go. But Definately no reason to go over 2mg, I rarely go over 1mg when done this way, usually a little less than 1mg..Bupe is 32x stronger than morphine, though it may not feel like it.
