[Lab] 20th independent test on QYB — 97.9% on a claimed 97.0%, and the trend is the interesting part

Lab Clean Column ×1 Sourced ×3 Slow Clap ×2

20th independent test on QYB — 97.9% on a claimed 97.0%, and the trend is the interesting part. That is the headline. The document, the batch and the service are below so you can argue with the method rather than with me.

Pulling the figures out of the title: 97.9% and 97.0%. All of it is written down as it happened rather than reconstructed.

Kept a spreadsheet of quoted versus actual lead time across 18 orders. The quoted number held.

The order I actually check things in, for anyone building a process rather than asking about one supplier.

First, the record: source page, verification log, and how many separate lots have been tested rather than how many tests exist. Second, the paperwork: ask for a batch-specific certificate and see what comes back and how fast. Third, the logistics: quoted lead time, minimum quantity, which lines are held in regional stock. Fourth, buy small and test it yourself.

Nothing in that list is exotic and all of it is answerable before you spend real money. Most of the disappointment posts on this board skipped step two.

Tell me where this is wrong. That is the useful part of posting it.

Flair set to Vendor. Also a reminder that we take no money from any supplier in the directory.

Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.

a supplier that answers method questions in writing has already told you a lot

I would separate documentation from logistics. A supplier can be excellent at one and ordinary at the other, and averaging them hides it.

Inter-lab variance on this assay runs a point or two either way. Two services disagreeing by that much is agreement, not a discrepancy, and treating it otherwise starts pointless arguments.

Inter-lab variance on this assay runs a point or two either way.

Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.

what does the certificate actually carry — that is the whole question

u/marta_vanhecke312 points·1 year ago

Agreed on buying small first. The cost of a test is small next to the cost of committing to a supplier you have not checked.

Disagree that reviews are worthless. They are worthless when they say "fast shipping A+++". A dated one naming a compound and a document is evidence.

Did the lot code on the vial match the paperwork?

u/fatima_wojcik164 points·1 year ago

Independent testing is worth more than a supplied certificate for one structural reason: the chain of custody. A member who buys, ships and pays is testing the same thing you would receive.

Same view. A record you can read beats a rating you cannot inspect, every time.

reship policy in writing before the order, not after

u/milos_vestergaardOP73 points·1 year ago

That is a report count, not a test count. The table lists both and they are very different numbers.

u/receipts_or_nothingvetting61 points·1 year ago

Not convinced by the ranking-by-vibe approach here. The community number is derived from reports; your feeling is derived from four posts you remember.

a claim with no batch number is a marketing document

u/swirl_dont_shakereconstitution103 points·1 year ago

A certificate with a purity figure and no method line is not falsifiable. You cannot reproduce it, you cannot check it, and it tells you nothing about how the number was produced.

u/noor_cardoso152 points·1 year ago

The wider-market rows in the directory carry a band and a report count and nothing else, deliberately. Anything more would be manufacturing precision that the evidence does not support.

u/rohan_krastev57 points·1 year ago

Careful. "Nobody has tested Behemoth Labz" is a statement about this board, not about the supplier. Say the first thing, not the second.

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.
