Here's what I do.
1. Start with 1 4mg pill. Take pill and put it into your spoon. Use the bottom of your lighter to crush it up. Doesn't need to be a fine powder, chunky is fine.
2. Take your rig and fill it with 50 or 60 units of cold water. Squirt it into your spoon on top of the now broken up pill. Take the end of your rig(plunger) and stir it around making sure you use pressure to break the chunks so the dissolve in the water.
3. Once your pill has been dissolved in the water take a nice size piece of cotton from a qtip or cig filter, about the size of a pea. Wet the ball of cotton and drop it in the middle of the solution. Start drawing back until all the solution is in your rig. You shouldn't lose much if any solution. If your solution doesn't look clear in the rig feel free to refilled until it's as clear as you feel it should be
4. Now, find a nice vein. Use a tournequit if you have to. Usually the vein in the crook of your arm is a good one to start with. Insert your needle at a 45 degree angle into the vein. Once the needle pierces the skin pull back on the plunger which will create a vacuum. Now keep pushing it into your vein until you see a nice dark red ploom of blood enter the rig. Once you've registered you're good to go. Loosen the tournequit, and start injecting. If at anytime you feel it stinging or pressure, stop, and really regeister. If it stings you're more than likely out of the vein and missing which is not good especially with pills. Once you've successfully injected the solution, pull the needle out, and take a piece of tissue and apply pressure. You should start feeling the rush not long after you've pulled the rig out.
5. Profit and enjoy the beautiful rush that dilauded gives. If you don't feel anything, try using 2 pills next time. But give it a little while before you attempt 2 pills, you don't want to overdose.
That's how I do it when I bang pills or anything for that matter. Alot of people will say to use wheel filters, but if you don't have any just filter multiple times until the solution is as clear as can be. Enjoy and be safe bub. Feel free to ask any questions and let us know how it goes
