[Math] someone check my arithmetic before i draw this up

Mathbranch of 10 comments

Posting this because I searched for it and got nothing useful. Setup: 0.5mg, week 2, sulphur burps present but not ruining anything. I changed exactly one variable — mg/mL — and tracked it for 9 weeks. Result: a difference, but a small one, and well inside what I would call noise if someone else posted it. So I am…

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

more water means more units for the same dose, which means finer resolution

Adding to this: dead space is doing more work than the comment implies.

Show the arithmetic. Where did the units come from?

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

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

Is that 5mg vial or 21mg?

Two vials, two different concentrations, forgot which was which, almost made a 3 times error. Now I label everything.

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.
