[Results] 2 weeks, 15kg, and mg/mL was the hard part
Genuinely asking, not being difficult. Everyone in c/cagrilintide repeats that dead space is important. I believe it, but I have never seen anyone show why, and when I search I get 4 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…
Dead space ate 13 units on a low-volume draw. Tiny impact at 0.5mg, massive impact at 0.25mg.
swirl, do not shake, or you are courting oxidation
dosing errors come from people reconstituting two vials differently and forgetting which is which
Did you write the concentration on the vial?
show your working or it is unhelpful
That is net peptide content, not purity. Different number, different meaning.
Did you write the concentration on the vial?
Disagree on that part. 98.9% and 99.0% on the same vial is normal.
never post a calculation as advice without stating the concentration
Dead space ate 13 units on a low-volume draw.
Yes, exactly this, and it is the bit that took me 86 weeks to accept.
30mg vial, 1mL water, concentration is 30/1 — write it on the vial afterwards
swirl, do not shake, or you are courting oxidation
i am begging people to write down the concentration
Dead space ate 18 units on a low-volume draw. Tiny impact at 2.4mg, massive impact at 12.5mg.
