i keep a spreadsheet of every vendor claim and whether it survived contact with a lab
i keep a spreadsheet of every vendor claim and whether it survived contact with a lab — a position I have arrived at slowly and would like tested. Why the directory has two tiers, since the question comes up whenever somebody new finds it. Twenty suppliers have enough independent results, over enough separate lots,…
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.
the lot on the vial has to match the lot on the certificate, every time

Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.
Minimum order and lead time — did they quote both up front?
Kept a spreadsheet of quoted versus actual lead time across 24 orders. The quoted number held.
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.
Paradigm Peptide came up in three threads the week I was ordering and I could not find a single independent result for them anywhere. Went with a documented supplier instead.
How many separate lots is that across? One lot tested twice is one data point.
Careful. "Nobody has tested Peptidology" is a statement about this board, not about the supplier. Say the first thing, not the second.
How many separate lots is that across?
