[Discussion] we are measuring Janoshik at the wrong time and calling it noise

Discussion Well Actually ×4 Receipts ×3 The Quiet One ×2

I have had 10 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 8 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.

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

positive and negative reports both need the same evidence standard

Sceptical.

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

The VendorInvestigate and Janoshik numbers on the same vial from TFC came back 97.4% and 96.2%. Both are right, inter-lab variance is real.

Is that a PeptideMeter result or are you quoting the vendor COA?

You have restated the marketing copy. What is the actual substance here.

u/zaid_eriksen476 points·4 months ago

order date, product, and what was tested. that is the template.

This order history matches mine almost exactly. Same vendor, same timeframe, same result.

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

Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.

one vendor per post, multi-vendor goes in the monthly thread

First order from BCH was great, second one had a different batch and tested lower. The vendor retested and credited me. Logged it here.

Not convinced. The evidence does not support that reading.

Respectfully this is a sample of one presented as a finding.

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.
