anyone else notice units kicking in around week 4
Posting this because I searched for it and got nothing useful.
Setup: 1.7mg, week 32, injection-site soreness present but not ruining anything. I changed exactly one variable — dead space — and tracked it for 20 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
I love that this community will spend 40 comments on a detail. That pedantry is why the numbers here matter.
Sceptical. If this were true we would see it reflected in the data and we do not.
Disagree. What you are describing is consistent with reconstitution, not with what you concluded.
the concentration on the vial in marker is the most important step
This is correct. 2mL versus 23mL is the common mistake.
dosing errors come from people reconstituting two vials differently and forgetting which is which
dead space is real and the syringe matters
never post a calculation as advice without stating the concentration
more water means more units for the same dose, which means finer resolution
stopper coring on the 15th draw because you keep using the same entry point. rotate.
Tracking number removed. It identifies both ends of a shipment.

Cored the stopper on my 18th draw because I kept using the same entry point. Rotate the puncture site.
Show the arithmetic. Where did the units come from?
more water means more units for the same dose, which means finer resolution
This is correct. 1mL versus 21mL is the common mistake.
Slight fix: the number was 98.4, not 98.3. Decimal point, but a fairly consequential one.

Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
Cosigning. The concentration on the vial in marker is load-bearing.
u-100 syringe, not u-40, or your math is off by factor of 23

Yes, exactly this, and it is the bit that took me 29 weeks to accept.
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

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
