my ALT moved and I cannot work out whether Janoshik is why

Discussion Clean Column ×1

Long-ish post, sorry. tl;dr at the bottom.

I have been tracking PeptideMeter against eGFR for 35 weeks because I could not find anyone who had. The correlation is weaker than I expected, which is itself mildly interesting given how confidently people link the two in here.

Caveats up front: one person, one lab, one assay, no control, and I changed my training in the middle of it, which was stupid.

tl;dr: probably real, definitely smaller than the threads imply, and not worth reorganising your week around.

independent test or vendor COA, which is it

No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

Reship, credit, or they ghosted you? That matters.

the PeptideMeter result being close to the claim is the signal, not the absolute number

receipts or nothing, sorry but that is the rule

SWB order #15, New Zealand, no drama, receipts inside

How many orders from SWB is that a sample of? One reship is noise, five is a pattern.

Crossposting this to c/maintenancephase because the people who need it are not reading this community.

Reship experience: SGN asked for photos, processed it in 21 days, sent a replacement no questions. That is the template.

The Janoshik and Medutest numbers on the same vial from KP came back 98.9% and 99.0%. Both are right, inter-lab variance is real.

Did you test the vial you received or are we going off the vendor COA?

The PeptideMeter and Medutest numbers on the same vial from Homopeptide came back 96.2% and 95.1%. Both are right, inter-lab variance is real.

About c/vendorvetting

The community due-diligence desk. Vendor experiences, independent third-party test results, shipping and reship records, and the boring paperwork that separates a supplier from a story. Every substantive claim is expected to carry a receipt: an order id, a dated screenshot, or a test report from Janoshik, Medutest, PeptideMeter or VendorInvestigate.
