tried concentration for 23 weeks. here is what happened.

PSA Clean Column ×7 Sourced ×3 Slow Clap ×2

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

Setup: 10mg, week 63, sulphur burps present but not ruining anything. I changed exactly one variable — insulin syringe — and tracked it for 11 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.

Cosigning. The concentration on the vial in marker is load-bearing.

The single most useful thing I did was write the concentration on the vial. Stopped all the confusion after that.

Spent 20 weeks confused about concentration math until someone showed me the table. 30mg, 3mL, concentration is 30/3.

Sceptical. If this were true we would see it reflected in the data and we do not.

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

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

never post a calculation as advice without stating the concentration

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

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

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.
  7. No referral links, discount codes or affiliate URLs. Permanent ban, no appeal.
