Stimulants Measuring out doses for IV methamphetamine?

[Royskopp]

I've smoked it several times and slammed it three times. However, I never slammed it myself (always had someone administer it.) This time I will be preparing and administering it myself. I'm relatively thin (maybe about 10 pounds underweight) also so I probably won't need as high of a dosage as someone of average/overweight weight.

I hear that .1 is a good dose to start slamming with (I assume .1 means .1 of a gram, so 1/10th gram?. But what does .1 look like? I know purity varies but for the sake of argument, let's say all meth was created equal. If I were to compare it to a match head how big is a .1 dose? Less? More?

Also would a 25 gauge needle be too much to IV meth? That's all I have access too and I'm not sure if it's the ideal size. Exact measurements on the syringe are:
3cc(ml)
25g x 1"
.50mm x 25mm

25 gauge is way too huge. Try 27, 29, or 31 gauge for IV shots.

Don't start injecting with 100mg (0.1g). That's way too much and will leave you tweaked to pieces. You cannot eyeball doses that low - don't even try. Meth is hygroscopic (absorbs water from the atmosphere) and can be powdered, crystalline, or mixed with cuts, so there's no telling just by a fast glance how much meth you have.

Get a good milligram scale (or at least one accurate to 10mg) and start with maybe 20mg (0.02g). Work your way up from there but don't rush it. Meth has a very long half life and you can get incredibly fucked up if you go chasing rushes or if you get greedy.
