This. A quoted lead time that holds is worth more than a fast one that does not.

the shortage listing has an expected resolution date on it

Have now spent more on testing than on some of the orders. No regrets — the log is the reason I can buy without agonising.

Spent 11 weeks confused about this until somebody drew the table for me. 10mg, 1mL, 10mg/mL, 2mg is 20 units. That is the whole thing.

Different laboratories use different assay platforms with different calibration. Comparing across labs adds a systematic offset that is invisible on the report.

If the report gives a mass spectrum as well as UV purity, say so. Identity and relative quantity are separate claims and the log tracks both.

ApoB counts atherogenic particles rather than the cholesterol they carry, which is why it can diverge from LDL-C and why it is the addition most worth making.

daily dosing changes adherence in both directions

GGPeps BPC, batch matched the paperwork, VendorInvestigate came back 99.6% against a claimed 99.0%. Paid for it myself, posting it because the log is only worth anything if people do.

Yes. Writing 5mg/mL on the vial takes four seconds and removes the entire class of error this board exists to fix.

Tested three lots over a year rather than three vials from one lot. Cost the same and told me something completely different.

Cosigning the seasonality point. February and August on the same lane are different animals.

if the maths gives you a fraction of a unit, change the concentration

Reconstituted at 2mL when I meant to use a different volume. Caught it because the units looked wrong on the barrel. Now I write 10mg/mL on the glass before I put the cap back.

Careful with the trend claim. Four results over two years is a very sparse series to draw a line through.
