I?ve tried searching and am having trouble locating the answers that I?m looking for. I?m brand new to injection of heroin(done it twice). Both times I used a full syringe worth of water to dissolve the H but going through a cotton filter I only managed to draw about half of that back into the rig. My question is is it normal to lose that amount of liquid due to absorption or is that an excessive amount and I?m just not doing it correct? Secondly I didn?t use citric either time and it didn?t seem to be an issue as far as dissolving the gear. Are there other benefits that I am missing by not using Citric or am I alright to continue to use without it? Any other advice or tips are just as appreciated as well so I welcome all responses. Thank you.
