Injecting - Problems preparing injectable subutex solution

[Swing]

Since subutex can't be cooked swim crushes up the pill in a spoon and adds water and mixes it up for around 2 subs. Now he has to add plenty of extra water cuz when you add cotton you'll only suck up some of the water you put in. Swim has also tried it on 1 pill per spoon x 3 and combined them for 24mg of bupe but when injected he didn't get high (it might have been cuz he used heroin in the morning but he did the bupe in the evening). Another method swim uses is to crush and mix the pills and pour it into a syringe with cotton to filter out a pure clean water to shoot. Swim is really wondering if there is something he can do better to get the most out of these pills because he knows if he had the same mg in an ampule he'd probably totally quit doing H.
