I completely advise you use a micron filter if you are going to shoot suboxone
strip/pill (or any pill) ! If not I'll explain a method to help you get most the particles out and leave you with a clear solution that is safer than nothing.
Take one of the insulin syringes and break the needle off. Take the plunger out of the back of the syringe & fill the syringe up to about 30ml's with cotton. Pack it down there good with the plunger. Ive also found adding layers of coffee
filters between the cotton helps as well. Sit this syringe aside for later use. Now break up the suboxone (never more than 2mg at once!!! Even for heavy users because remember IV gives you 100% bioavailability) and place it in a spoon you've cleaned good with alcohol
wipes. Keep everything sterile! Do not heat suboxone you will only make the shot weaker and get more fillers into the solution. Add ~80cc of cold water to the suboxone in the spoon. Let it sit for 10-15 min. mix with tooth pick to make sure it is all dissolved. Drop in a ball of cotton and suck the liquid through it into the unused insulin syringe.
Take the plunger out of the insulin syringe you packed with cotton and back load the suboxone solution from the other insulin syringe into this one. Now in the clean unused spoon push the plunger through the filtering syringe and watch the liquid slowly push through the cotton into the clean spoon. It should be a more clear solution by now. Now drop another cotton ball into this spoon & suck up the solution into a clean syringe. Now you should have almost a 100% clear solution in a clean and sterile syringe ready for injection. This isn't 100% safe and particle free but it should get out a lot of the dangerous particles from shooting strips. Shooting is NEVER safe, but this is as close as I can get from household items without getting a micron filter. It's better then just filtering with a cotton and shooting. You should get back about 70 units of water out of the 80 units you strated with.
Tie off, find a vein, swab your arm with alcohol, register, & shoot off. Make sure you loosen your tourniquet before injecting to avoid leakage. You should experience a bit of a rush or at least be free of WD symptoms. I just wish the buzz lasted longer.
I found this to be the best way to shoot sub strips or any pill in general. Remember do not over use the same vein too often because some fillers can get through and your veins will harden and become severely damaged. Best of luck!
