[Janoshik] WWB sema 10mg — 98.6%, batch and method inside

Janoshik Long Haul ×2

I have had 8 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 10 days on nominally the same lane, which matters more in summer than in February.

The independent number came back 93.7% against a claimed 98.6%, 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.

Strongly agree. Below-spec results matter as much as good ones.

inter-lab variance is real, 20 points is inside normal

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

Tested 18 batches from TFC over 54 weeks. Spread was 98.3% to 98.1, mostly 98.3. Consistent vendor.

the VendorInvestigate and Medutest results differ by 7 points, both inside inter-lab variance

Every time this gets posted it hits the front page and every time someone has to re-explain it.

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

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