[Question] Janoshik — what am I missing here
Trying to settle this properly because the thread from last year went in circles.
The claim: Medutest matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 5 months without either producing anything.
What would actually settle it is 31 people measuring the same thing the same way. I have started; my numbers are below. They lean one way but not strongly enough for me to declare victory.
If you have data, post the data. If you have an opinion, flair it as an opinion.

Is that 98.4% area or mass?
Strongly agree. Below-spec results matter as much as good ones.
the VendorInvestigate and PeptideMeter results differ by 13 points, both inside inter-lab variance
multiple batches from JEEP show a spread, that is the data
the 98.1% result confirmed the vendor claim, that is the signal
Not to be pedantic but Janoshik and PeptideMeter are being used interchangeably and they are not interchangeable in real life.

Disagree on that part. 95.1% and 93.7% on the same vial is normal.
Was that the vendor COA or your own test?

Yeah, the PeptideMeter number matching the claim is the actual signal.
inter-lab variance is real, 10 points is inside normal
Homopeptide / BPC / batch 9 / Medutest / 99.0% — that is the shape
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.
This result fits the template perfectly. Logged.
Removed a chain here. The rule is one line long and it is not negotiable.
Homopeptide / BPC / batch 5 / PeptideMeter / 99.0% — that is the shape

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

Sceptical. If this were true we would see it reflected in the data and we do not.
