Reconstituted at 3mL when I meant to use a different volume. Caught it because the units looked wrong on the barrel. Now I write 1.67mg/mL on the glass before I put the cap back.

Yes — the withdrawal literature is consistent and it is a pharmacological finding, not a moral one.

What is the one column you added late and wish you had from the start?

That reads as a warning about a documented supplier and the events you describe are about a shop nobody has any record of.

Push back: that is a taper schedule aimed at another member and this board does not host those.

Yes.

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

Where a supplier has no independent testing on file, that is a statement about the evidence and not about their conduct. Saying it the second way is how this board would stop being useful.

Bacteriostatic water contains benzyl alcohol as a preservative, which is what makes repeated entry into the same vial reasonable. Plain sterile water has no preservative.

How long were you at the dose you are coming off?

Left up.

spreadsheet_gremlin is right about blanks. Silent gaps make the series lie.

The arithmetic in full: concentration is mass over volume, so 20mg into 2mL gives 10mg/mL. A U-100 syringe is graduated at 100 units per millilitre, so 5mg is 5 divided by 10 millilitres, which is 50 units.

interval stretching is the most commonly described approach here

Stretched from seven days to ten to twelve over four months. Appetite told me where the limit was each time.

bacteriostatic water has the preservative, sterile water does not

Cosigning the round-number approach.

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

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.

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

That is sterile water, not bacteriostatic. Same appearance, different product, and it matters for a multi-draw vial.

Small fix — a U-100 syringe is 100 units per mL. If yours is marked differently it is not U-100 and the whole calculation changes.

Correcting myself above: I wrote the concentration the wrong way up. Mass over volume, not volume over mass.
