Glad you decided to start with a smaller shot and that you're alright
tentram's advice is spot-on. Vacuum method FTW
use the "vacuum" registering method. simply pull back the plunger a little as you first insert the needle to create a vacuum seal, so as soon as you enter the vein it will flag/register and have blood flow into the syringe meaning you've successfully entered the vein. enter it as parallel/small as angle as possible. depending on what vein you use will determine how far in the tip will be.
Just to be clear, you have to insert the needle a little before pulling back on the plunger, to make sure it has a seal and so will actually be creating a vacuum and not just letting air in. Keep inserting it and as soon as some blood enters the syringe, stop moving the needle and then pull back on the plunger a little more to make sure more blood enters showing it's still in the vein. Then start injecting slowly. Also insert the needle at a shallow angle and with the bevel on the needle facing up.
It's best to hold the syringe in such a way that you can insert, register and inject without removing your hand from the syringe. Here's one example of how to hold it, but you can play around and see what feels best for you:
And the rigs I was able to get are .5ml (half cc)/28 gage. I tried to get 1cc but they didn't have them. The half cc doesn't seem like it can hold too much. (1cc is like a bigger/wider barrel than a half cc, correct?) How much tar do you think I would be able to fit into one of these half cc rigs? And how many units of water should i be using for every .1 of tar?
A 1CC or 1ml syringe holds 1CC/1ml of liquid, whereas a 1/2CC/.5ml syringe holds 1/2CC/.5ml of liquid (up to the lines). But in reality you wouldn't want to put that much liquid in because you need to have space to be able to pull back and register. If you fill it too full, it makes registering difficult. As to whether the barrel on a 1CC is wider, I think it depends on the brand, it is usually a little wider plus longer, here's a pic:
Anyway, 1CCs aren't necessary with heroin, and they often come with thicker/longer needles, so that's something to keep in mind/check. But with a 1CC you don't have to be as worried about putting in too much water. You can measure the water you're going to be adding in the syringe first, then squirt it into your spoon, so you have a rough idea of how much liquid there will be in the final solution (it may change very slightly because if you're heating it some water might evaporate or some cuts might get dissolved that add to the volume of water). You should be able to fit a
lot of heroin in a very small volume of water. How much water you use is really up to you, as long as you don't use so much that it can't fit in the syringe or fills it up.
And one more question: What would you all suggest the best way to prepare/cook this stuff is? I just dissolved it with water in a spoon and heated it up some with a lighter under it, then threw in a small piece of cotton from a q-tip to filter. From there I just withdrew from the cotton and pushed the air out and went at it. Am I doing everything right for the most part? Would you change anything?
I would use a micron filter if at all possible, or at least a Sterifilt or something. I would also try to avoid heating it if possible and just try stirring it. The actual heroin
should be able to dissolve without heat and any cuts that don't dissolve you wouldn't want to dissolve anyway. This is a matter of controversy on here, with most people saying it's best to not heat it at all so that the cuts that aren't soluble in room temp water don't dissolve, but some people saying tar needs heat to dissolve and/or that you should heat it because heat might kill off some bacteria/viruses if present (although if you're using sterile syringes/filters/cookers there shouldn't be much bacteria/viruses and heating for a short time does not sterilize it, only kills
some things). I would clean your spoon with alcohol before each prep, or use a sterile cooker (which should also be cleaned before each use). And use sterile water. I guess it's hard to get this stuff if you live in Texas
I also had a little trouble getting all of the little teeny tiny air bubbles out. Is it a problem/big deal if there are just a few of those tiny bubbles left in there?
No, it actually takes a
lot of air to cause problems, like a lot more than you could fit in a 1/2CC or 1CC syringe. But it's still best to get as much of the air out as possible. Turn the syringe upside-down (needle pointing up), then flick the barrel with your fingernail to get the air to all go to the top, then slowly push up on the plunger to eject all the air without ejecting any of your liquid.
Other tips:
Never re-use syringes. This is horrible for your veins and makes it harder to register. Even if you just are having trouble registering and haven't actually injected with that syringe yet, switch the liquid into a fresh syringe and start again.
