6 months in and insulin syringe is still the thing I get wrong

Correction Receipts ×6 Sourced ×1 Well Actually ×1

Posting this because I searched for it and got nothing useful.

Setup: 12.5mg, week 39, constipation present but not ruining anything. I changed exactly one variable — bacteriostatic water — and tracked it for 4 weeks.

Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am putting it here rather than presenting it as a finding. If two or three other people have done the same thing we might actually learn something.

Not medical advice, obviously. This is one person with a spreadsheet.

Reconstituted at 3mL when I meant 12mL. Caught it because the units looked wrong. Write the concentration.

Disagree but this is the good kind of wrong — it is specific enough to be checked.

dosing errors come from people reconstituting two vials differently and forgetting which is which

dead space is real and the syringe matters

What was the vial size and how much bac water?

Removed a chain here. The rule is one line long and it is not negotiable.

Yeah, showing the arithmetic is the fastest way for someone to spot the error.

About c/reconstitution

The arithmetic and the technique. Bacteriostatic versus sterile water, reconstitution volume as a concentration choice, converting mg/mL into insulin-syringe units, dead space, swirl-not-shake, stopper coring, and how long a reconstituted vial is actually good for. Math errors get corrected fast and politely.

c/reconstitution rules
  1. Show your numbers. "How many units?" with no mg and no mL cannot be answered.
  2. Never post a calculation as advice without stating the concentration it assumes.
  3. No sterile-compounding-for-others discussion. Personal handling only.
  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
  5. Not medical advice. Describe what you did; never prescribe to a stranger.
  6. Claims need evidence. Batch numbers, dated screenshots, independent test reports, or a citation.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
  8. No contact handles, wallet addresses or tracking numbers — they identify people.
  9. Be recognisably decent. Disagree hard, insult nobody.
