is it normal to get nausea at week 19

Question Receipts ×5 Long Haul ×3

Something I noticed reading old threads that I have not seen said out loud.

The advice on insulin syringe in this community changed substantially around the start of last year, and nobody went back and updated the older posts. So depending on which thread the search engine hands you, you get two contradictory answers with the same confidence.

I have listed what I think the current consensus is below. Correct me — that is the point of posting it.

Mechanistically the bit that matters is reconstitution. It explains most of the early profile and a decent chunk of the outcome.

Retitled to remove editorialising. Put the evidence in the body.

swirl, do not shake, or you are courting oxidation

Not convinced. The evidence does not support that reading.

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

The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.

Is that 15mg vial or 16mg?

dead space is real and the syringe matters

stopper coring on the 23th draw because you keep using the same entry point. rotate.

Spent 5 weeks confused about concentration math until someone showed me the table. 20mg, 2mL, concentration is 20/2.

Small correction: the trial was 11 weeks, not 3. Does not change your point but people will quote it.

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.

  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.
