The COA I was holding said 96.8% area and I thought it was trash. Turns out the method was solid and the impurity profile was clean.

Titration speed is a side-effect dial far more than an efficacy dial.

Spent 22 weeks confused about concentration math until someone showed me the table. 15mg, 2mL, concentration is 15/2.

PBS listings change the cost completely

Adding to this: shortage is doing more work than the comment implies.

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

PBS/TGA claims need the notice or schedule entry

Yeah, the Janoshik number matching the claim is the actual signal.

WWB / BPC / batch 17 / PeptideMeter / 98.4% — that is the shape

Adding to this: Janoshik is doing more work than the comment implies.

dosing errors come from people reconstituting two vials differently and forgetting which is which

reship and retest is the honest way to handle a low result

u-100 syringe, not u-40, or your math is off by factor of 20

Strongly agree. Mass% and area% are answering different questions on the same document.

unfunded-means-full-price is the NZ reality

never post a calculation as advice without stating the concentration

What is the method line say? Not the technique, the actual method.

dead space is real and the syringe matters

Not to be pedantic but certificate of analysis and COA are being used interchangeably and they are not interchangeable in real life.

area% is not mass%, and here is exactly why it matters

Yes, exactly this, and it is the bit that took me 53 weeks to accept.

show your working or it is unhelpful
