I cook it up, pull it through the filter, so I have my syringe ready. (Altought I'm still a lil unsure about the amount but I'm slowly getting there) but the bigger problem I have is, even though I have very good veins, very visible, palpable and all that, when I puncture it and try to pull the plunger back (which is harder than you might think) I almost never draw blood, even though I'm 100% sure I'm inside a vein, so I can't shoot up. And that frustrates me to no end. I have such craving and everything's ready and then I try like 7 different spots and none of them work. What am i doing wrong? How to properly do this? I lost and I would love to shoot up without my arms and the bathroom looking like a crime scene afterwards. Maybe someone has some tips? Would be greatly appreciated, thanks guys
