[Explainer] why 1mL syringes cause overdoses and 0.3mL ones do not

Explainerbranch of 8 comments

Genuinely asking, not being difficult. Everyone in c/orforglipron repeats that dead space is important. I believe it, but I have never seen anyone show why, and when I search I get 17 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…

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

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

That is net peptide content, not purity. Different number, different meaning.

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

swirl, do not shake, or you are courting oxidation

This is correct. 1mL versus 15mL is the common mistake.

This is the "correlation is mechanism" thing again. You changed three variables at once.

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.
