stalled for 2 weeks at 7.5mg and I refuse to panic this time

Below Spec Well Actually ×4 Clean Column ×2 Cold Box ×2

I have had 24 orders now and I keep a table, so here is the honest summary rather than a vibe.

Material has been consistent. Communication has not. Shipping has varied by about 28 days on nominally the same lane, which matters more in summer than in February.

The independent number came back 97.9% against a claimed 94.2%, which I read as agreement rather than a discrepancy — inter-lab variance on this assay is a point or two either way and treating one lab as ground truth is how people end up in pointless arguments with vendors.

Batch number is in the comments. Ask if you want the method.

Disagree but this is the good kind of wrong — it is specific enough to be checked.

do not editorialise in the title, put the number in the title and the opinion in the body

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

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

multiple batches from SGN show a spread, that is the data

This is the "correlation is mechanism" thing again. You changed three variables at once.

This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.

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

testing the vendor claim versus testing your actual vial are two different posts

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

SSA / BPC / batch 20 / PeptideMeter / 98.3% — that is the shape

Yes, exactly this, and it is the bit that took me 83 weeks to accept.

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

Slight fix: the number was 97.2, not 97.4. Decimal point, but a fairly consequential one.

inter-lab variance is real, 16 points is inside normal

Is that 98.4% area or mass?
