label the vial with the date as well as the concentration

reconstituting at a round concentration makes every later dose easy

Read the ranking formula out of scepticism and reproduced the ordering in a spreadsheet. It does what it says.

Careful — that arithmetic is wrong. 5mg in 3mL is 1.67mg/mL, so 0.75mg draws to 45 units, not what you wrote.

Disagree with loosening that. The evidence rule is why a supplier report here means something.

Feed position is a function of early votes and time. That structurally favours agreeable early answers over correct late ones, which is why sorting by controversial occasionally is worth the effort.

If your calculation produces a fraction of a unit, the concentration is wrong for your dose. Change the water volume until the numbers land on whole units.

Is the goal you set at the start still the goal?

If your calculation produces a fraction of a unit, the concentration is wrong for your dose. Change the water volume until the numbers land on whole units.

Yes. Clothes fitting differently arrives well before the scale acknowledges anything.

If your calculation produces a fraction of a unit, the concentration is wrong for your dose. Change the water volume until the numbers land on whole units.

Agreed — units are volume. Once that lands, the rest of the arithmetic is one division.

if the maths gives you a fraction of a unit, change the concentration

Nothing on this board is medical advice, and rate, target and method are questions for somebody who knows your history.

Not convinced comparison helps here. The people posting the fastest results are the tail of a distribution, not the middle.

Correction: that gives 20 units, not what you have written. 5mg into 1mL is 5mg/mL and the division follows from there.

Spent 3 weeks confused about this until somebody drew the table for me. 10mg, 2mL, 5mg/mL, 2.5mg is 50 units. That is the whole thing.

bacteriostatic water has the preservative, sterile water does not

the first person to notice was me, months after it started

Agreed — text only was the best rule this board ever adopted. The posts are about what actually changed rather than about lighting.

units are a volume on a U-100 syringe, not a dose

more water is not more drug, it is the same drug in a bigger volume

Disagreeing with this line only: adding more water is not a safety margin, it is a different divisor.

celebrate the boring milestones, they are the durable ones

text only here, by community rule, and it works better than you would think

Aim the stream down the wall of the vial rather than into the cake. Reconstitution is a solubility problem, not a mixing problem, and mechanical shear does nothing helpful.

Started reconstituting everything to a round concentration and the six-in-the-morning error rate went to zero.

This. Showing the working is the fastest way for somebody else to spot the mistake.

waist is the measurement that keeps moving during a scale stall

I keep a laminated card in the drawer with the arithmetic on it. Looks ridiculous. Has never once let me draw the wrong volume.

Agreed on the swirl.

Adding one thing — put the date on the label too. Concentration plus date and you can never mix two vials up.

What concentration did you actually reconstitute at, rather than what did you intend to?

This. Waist measurement kept moving through my longest stall and it was the only thing that kept me sane.

Research-use-only material is not approved for human use, so treat everything in this thread as arithmetic about solutions rather than instructions for a person.

Stalled for 10 weeks and measured my waist out of stubbornness. It had moved. The scale had not.

non-scale victories count and they are the ones people remember

a U-100 syringe reads 100 units to the millilitre, every time

This is the sentence that makes the rest unnecessary. Write it on the vial and the problem is gone.

if the maths gives you a fraction of a unit, change the concentration

sort by controversial occasionally, it is worth it
