Okay, I'll write a guide since I doubt youll be persuades, you might as well do it right.
1.poor you're smack into a spoon
2.draw up about 20 units of water, I often used bottled water (Poland spring, it just seems fresher)
3.spray the water you drew up with you're syringe onto the dope. Pull the plunger out of the syringe and stir the solution until its well dissolved. It the plunger back in the syringe.
4. Take a q-tip, and pull off a small piece, about the size of 1/4 of a pea. Roll it into a tight little ball and throw it into the spoon on top of the heroin solution. The cotton should swell.
5.stick the point of you're syringe into the cotton, and pull up on the plunger. You should be able to draw back up 20units. If you came back with 15, or less you used too big of a cotton.
6. If you use a tourniquet, put it above the crook of your arm, not too high up. Flex your muscle, your big vein should pop up.
7.insert the syringe beveled edge up at a very shallow angle into the vein. Once you pierce the skin pull up. This will create a vacuum so that when you hit the vein, the blood will just flood up the barrel, and you won't have to worry about slipping out of the vein while registering (drawing up you're blood).you might have to push in a bit deeper or adjust the angle of the syringe to hit the vein. This is not ideal, so you should try to visualize the needle in relation to the vein so you don't go through it. However once you hit the vein and the blood shoots up your syringe, loosen the tourniquet.
8.with steady hands draw back a bit more so that you know you're still in the vein, as it might have slipped out while loosening the tourniquet. IMO tourniquets or more of a hindrance than a help when your basilic vein still works, for this reason. If you're not using a tourniquet you can just inject once the blood runs up the barrel, otherwise you better register a little bit more to make sure you didn't slip out.
This technique of creating a vacuum really helped me out when I first started injecting, as the main problem I always had was keeping the syringe in the vein while registering. IMO, as I said above, tourniquets really aren't necessary unless you have very small veins, or have a lot of meat on your arms. Hopefully this helps.
