[Discussion] the PeptideMeter advice in here is 8 years out of date
Trying to settle this properly because the thread from last year went in circles.
The claim: PeptideMeter matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 18 months without either producing anything.
What would actually settle it is 13 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.
best — the order this archive was captured in
the Janoshik result being close to the claim is the signal, not the absolute number
GGPeps took 18 days to answer an email and the material was flawless. Both of those things are true.
Is that a PeptideMeter result or are you quoting the vendor COA?
The evidence standard in c/vendorvetting gets called too strict about once a month, and every time, the thread ends with the complainant agreeing.
Flair changed to match the content. Read the sidebar before posting next time and we are square.
Cosigning the evidence standard. Receipts make the community.
Did you test the vial you received or are we going off the vendor COA?
the batch number or it did not happen
This order history matches mine almost exactly. Same vendor, same timeframe, same result.

Yes, exactly this, and it is the bit that took me 84 weeks to accept.
How many orders from FGP is that a sample of? One reship is noise, five is a pattern.
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

did they reship, credit, or ghost you?
How many orders from FGP is that a sample of?
Disagree on that part. 98.7% and 98.3% on the same vial is normal.
Went through three vendors to find one that actually ships on-time and tests clean. The answer was WWB.
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
Disagree but this is the good kind of wrong — it is specific enough to be checked.
vendor staff must self-identify, full stop

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