switched from 0.25mg to 15mg and the injection-site soreness got better, not worse
Posting this because I searched for it and got nothing useful.
Setup: 1.0mg, week 49, sulphur burps present but not ruining anything. I changed exactly one variable — insulin syringe — and tracked it for 3 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.
best — the order this archive was captured in
dosing errors come from people reconstituting two vials differently and forgetting which is which
This is correct. 2mL versus 22mL is the common mistake.
stopper coring on the 19th draw because you keep using the same entry point. rotate.
swirl, do not shake, or you are courting oxidation
Are you using a u-100 or u-40 syringe? That changes everything.
Are you using a u-100 or u-40 syringe?
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

Removed a chain here. The rule is one line long and it is not negotiable.
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
30mg vial, 2mL water, concentration is 30/2 — write it on the vial afterwards
dead space is real and the syringe matters
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
bacteriostatic and sterile water are not interchangeable, do not use them that way
Spent 3 weeks confused about concentration math until someone showed me the table. 10mg, 1mL, concentration is 10/1.
Dead space ate 22 units on a low-volume draw. Tiny impact at 15mg, massive impact at 0.5mg.
Is that 30mg vial or 26mg?

15mg vial, 2mL water, concentration is 15/2 — write it on the vial afterwards
u-100 syringe, not u-40, or your math is off by factor of 14
more water means more units for the same dose, which means finer resolution
Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.
