Mislabeled TR60/TR10 vials and syringe versus pen unit math disputes

Sure that's right. The single-use injector I rely on came loaded with twenty milligrams of Tirz mixed into two milliliters of Bac Water. After five separate two-milligram doses the reading shows one hundred twenty units. Work out the math. These suit me since three such devices cover everything.

Great job slimming down... Yet the facts posted here contain errors a beginner might follow into bad choices and this could really count.

Have a look at the injector featured below. Loading a two ml cartridge makes the dial show two hundred forty units. Where did my math go off?

???

I wonder if that pen came from Belgium or if it was filled by hand. It looks nothing like the ones we have around here.

These arrived from overseas too. They are meant to match the original brand. They lock firmly once loaded up. I picked up several reusable versions early on but they measured wrong so tossed the whole set.

I'm having trouble figuring out why someone would think that this pen shows 60 units as half a milliliter. Please don't get upset, but I believe there's an inconsistency in that idea. Usually these devices follow a standard where each unit represents one hundredth of a milliliter, meaning half a milliliter should correspond to fifty units instead. Can you tell me what amount gets selected on the dial for delivering two milligrams when the strength is ten milligrams per milliliter, as I recall you mentioned?

what he said

The packaging claimed the item was TR-60 while also listing 10mg for every container. Those details didn't line up. It really was TR-60 and the packaging simply had a mistake.

Two hundred forty divided by ten. Two hundred forty units equals two milliliters equals twenty milligrams.

I'm wondering about all the comments claiming each unit equals 0.01 milliliters, so half a milliliter would come to fifty. You're still certain your device marks that volume as sixty instead, even after searching online or consulting an AI yourself. That kind of rock-solid assurance against everything out there really stands out to me. In my case I'd probably start wondering if I'd messed up the measurement or if the device itself had a problem. I second-guess myself constantly and wish I could match that kind of certainty. Is this device actually intended for animals? Even those versions treat half a milliliter as twenty units.

I've noticed that the fifty-unit versions tend to hold just half a milliliter yet measure doses identically to the hundred-unit kind. Some folks end up choosing tuberculin types when working with pharmacy-mixed substances since those get included with the peptides and the amounts get listed in milliliters rather than units.

I agree that's correct, however it has nothing to do with the post I responded to. Moreover the diagram shared indicates that the syringe used for tuberculin has markings every 0.01mL/0.1cc, and that seems wrong since milliliters match cubic centimeters exactly.

I guess the picture is showing those extra lines that are on the back side of the syringe.

You can spot those 0.01 milliliter lines right on the picture. The mix-up seems to come from the way it labels the scale as 0.01ml over 0.1 cc, and that part checks out, yet the text ought to explain the lines themselves go from 0.01ml up to 0.1ml.

This part leaves me uncertain about the claim that the dosage ratio counts as accurate, since I can't tell exactly which detail is supposed to be right. It comes across as suggesting those two units match up when they clearly don't. I wonder if extra lines appear on the tool itself. The suggested angle for the shot also seems off because the image looks more slanted without pointing out much variation in the method shown. The whole diagram has me puzzled. Just to be upfront I'm not looking to debate anything and only want to sort out the confusion here.

Never complain about getting eighty three percent less than you paid for?? What?!

Your truth is still inaccurate. One unit isn’t zero point zero two milliliters. One unit is zero point zero one milliliters.

I believe the left syringe displays 0.01 milliliter marks on the visible face, numbering every tenth, while the hidden back has matching increments possibly without extras but marked in cubic centimeters. This matches the description in that list item. Similar to how a cooking measure jug shows various volume units side by side on its edge. Simple math works it out yet most folks don't grasp it readily.

IM is ninety degrees. SubQ is forty five degrees. If the graphic you reference shows otherwise, it is incorrect.

That's my point.

I wonder if you get how rhetorical questions work. Pretending to be puzzled helps me avoid sounding argumentative. That tends to make others clarify their views without turning guarded. You look defensive at the moment. My apologies for stirring you up.

From what I gather the plan is for the fine lines to stay blank while the bigger steps get the numbers shown. What gets me is how the smallest ones get called milliliters yet the next size over switches to cubic centimeters. Keeping everything in one unit the whole way would clear up the mix.

It looks to me like neither goes into muscle tissue. The first sits beneath the skin while the second stays in the skin layer just above that spot. That explains why a tilted needle works fine for each.

I can see some logic there. It looks like they prioritized brevity over making things clear. What's amusing is how this misses the main point I brought up earlier about that syringe with fifty markings where each was said to equal an IU. Seems like most replies in this discussion overlooked that key detail.

I didn't mention intramuscular injections at all. Someone else brought that up. The diagram aims to contrast injections into the skin layers versus under the skin. It'd be better if folks actually looked at my original comments instead of assuming things I didn't say.

Yeah, that checks out. What they mentioned only held if other factors applied, keeping the whole thing right.

Yeah it looks like they're totally mixed up on measurements and stuff and won't listen to other opinions at all. I think they also claimed their injector treats half a milliliter as sixty units.

I wanted to clarify the sequence of events in this discussion to avoid any mix-up. One person showed a syringe of one milliliter capacity marked with fifty divisions and stated that each division represented a unit. My response was that this division actually equals zero point zero two milliliters and cannot be considered an international unit. Following that, another participant shared an explanatory image which only created more uncertainty. I highlighted a pair of inaccuracies in that image. A third user then agreed with my points on those inaccuracies, apparently viewing it as an opportunity to surprise me.

Instead of guessing, perhaps examine the image directly. My intent is not to start an argument, yet many answers appear to address my statements separately without grasping the entire exchange.

That's exactly the topic I meant to discuss before.

This points to the pen being off on its measurements. Sixty clicks producing half a milliliter has no importance whatsoever.
