week 71 check-in — 6kg down, constipation manageable, one thing confusing me

Math Slow Clap ×3 Sourced ×2

Genuinely asking, not being difficult.

Everyone in c/orforglipron repeats that concentration is important. I believe it, but I have never seen anyone show why, and when I search I get 2 threads of people agreeing with each other.

Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?

I am not trying to be the "source?" guy. I would just like a source.

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

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

This is correct. 1mL versus 2mL is the common mistake.

Disagree. What you are describing is consistent with insulin syringe, not with what you concluded.

u/ines_ekstrom22 points·1 months ago

u-100 syringe, not u-40, or your math is off by factor of 19

Show the arithmetic. Where did the units come from?

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

This is correct. 2mL versus 2mL is the common mistake.

30mg vial, 2mL water, concentration is 30/2 — write it on the vial afterwards

dead space is real and the syringe matters

Disagree on that part. 98.1% and 98.4% on the same vial is normal.

Small correction: the trial was 15 weeks, not 23. Does not change your point but people will quote it.

bacteriostatic and sterile water are not interchangeable, do not use them that way

Did you write the concentration on the vial?

This is correct. 1mL versus 12mL is the common mistake.

the concentration on the vial in marker is the most important step

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.
