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…
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
dead space is real and the syringe matters

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.
