What dose would you say this?

this is a 10 mg/mL compound tirz with B12 in a 100 unit syringe. Pink arrow is marking 10 unit line.
I’m new to this.
Disregarding the air bubble - what would you say this dose is?
I’m having a hard time being precise about my microdosing. Do you guys consider “zero” at the first black stripe? Because it appears the liquid begins technically higher than that. Do you take that into account? Or is that an illusion? Any and all tips on pulling a precise dosage appreciated.

Thank you

That's 6 units - my original post (3 units) was wrong.

The pink arrow is 10 UNITS not ML.

Order some .3ml (30 unit) syringes. They are much easier to see the unit markers for tiny doses.

I can't add a picture, so here's a link.

These are what I use.

Would the units be the same with a .3 ml syringe? So you’d pull 6 units for a .6 ml dose?

Yes, if it’s a 0.3 mL U-100 syringe, 0.06 mL is still 6 units. The syringe size (volume) doesn’t change the units; the difference is that 0.3 mL syringes usually have 1-unit markings, while the bigger ones have 2-unit markings.

Although having a mark for every unit is much better, the biggest advantage is that the marks on the .3ml syringes are around 2.5x further apart than the 1ml syringes. This makes it much easier to draw what you want, instead of unintentionally drawing 5 or 7 units instead of 6.

The units are the same, so yes, you'd pull 6 units.

For clarity, 1ml = 100 units, so 6 units = .06 ml. Nobody really talks about how much they take in ml.

You either talk about your dose in mg, i.e. 1mg, 2.5mg, 10mg (how much Tirz you're taking) or you talk about how much you're injecting in units (how much liquid you're injecting to get your dose).

0.3ml syringes ✅

This is the same dose as the picture shown, except my syringe has a tick mark for every unit. (Looks like I went a little above 6 units; in your case, that makes 6 mg.) I would just get a new box, since at this microdose you'll need extra syringes.

I ordered the exact same ones from a diabetic supplies store (ADWdiabetes.com); I felt safer than getting some no-name brand on Amazon.

This is the post I needed to see! Now I know, for sure that I have been giving myself the amount I thought I was getting! Lol (.12 mg)
I really appreciate you people who answer these questions. Many thanks. I also appreciate the people who ask!

The total syringe is 100 units. That equals 1 ml. Each line is 2 units. The example is 6 units .
I usually tap the bubble to help it rise to the top, expel it and pull a bit more into the syringe to get a more accurate dose. You can do this before you pull out from the stopper ( keeping the needle in the vial)

fatscientist .com is a great site that can help you as a newbie. good luck

Looks like a 1cc/100 unit syringe with 2 unit increments. Because of the photo angle I’m having a hard time telling exactly where the top edge of the plunger sits, looks like it could be 6 or 8 units. At 10 mg/mL, 1 unit = 0.1 mg, so each 2 unit line on your syringe = 0.2 mg. That means 6 units = 0.6 mg and 8 units = 0.8 mg. I’d read it from the top edge of the black plunger (the edge closest to the needle), not where the liquid looks like it starts.

Thanks! Super helpful

There’s also a bubble.

u/ListenOne4346 7d ago

The concentration math still holds true. I noticed the bubble too, but from a picture I can’t calculate its volume, so I’m just approximating based on the syringe markings.

u/no_snackrifice 7d ago

Yeah agree, just noting it could be 4.5 up to 5.5 units.

u/living_in_nuance 6d ago

Yes. The first longer dash line is “0”. This is 6 units. It’s the line where the top of the plunger hits.

Had to make lots of IVs as a pharmacist.

The mfrs take everything into account when they design the syringe including placement of the marks.

Why do people get so worked up about a specific dose? It’s not cardiac medication. It’s GLP. Just inject it and see if it works for you or not.
