the Medutest rule is doing its job and people should stop complaining. This affects how posts get sorted and removed, so it belongs in the open. Inter-lab variance on…
Medutest — 16 things I got wrong before I got it right — a position I have arrived at slowly and would like tested. Chain of custody is why member-funded testing is…
split one vial across Medutest and Janoshik — 97.6% and 95.1%. That is the headline. The document, the batch and the service are below so you can argue with the method…
Something I keep coming back to: we need a standard template or these posts are unsearchable. Kept every report as a PDF with the batch in the filename. Two years in,…
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.
Browse resultsTitle says it — WWB sema 10mg — 98.6%, batch and method inside — so here is the boring supporting detail that makes it worth anything. 10mg and 98.6%. Those are…
test results — 21 things I got wrong before I got it right. Change my mind, genuinely — I have no stake in being right about this. Date of analysis anchors the result…
Genuine question, and the title is the question: how much of what we believe about purity actually comes from below spec threads. A series across separate lots…
Question in the title, detail here: help me understand below spec, I have read the wiki twice. The template is vendor, compound, batch, service, claim, result, and who…
Right: four vendors, same compound, same week, one test each. I paid for this one myself, nobody sent me anything, and the receipts are in the comments. QSC BPC, batch…
Posting this because it is the worst result in my log and hiding it would be pointless. Field Value Vendor not naming yet — see below Product semaglutide 10mg Service…
Short version of the title, which is already short: WXT BPC — PeptideMeter came back 97.2% against a claimed 97.0%. Longer version underneath. Numbers, in the order…
FGP vs SWB on the same compound, same month — both cleared 99.0%. I will put the method line and the batch identifier up front because that is what makes this…
why does nobody talk about Medutest. If this has been answered properly somewhere, link me and I will delete. Date of analysis anchors the result to a manufacturing…
Housekeeping: proposal — a flair for PeptideMeter posts. How to build a series that means something, if you are going to spend money on testing anyway. Three tests on…
does Medutest actually matter or is it forum lore at this point, and I want the answer with the reasoning attached rather than just the conclusion. Area percent and net…
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.
Reference standardsAsking properly rather than in a comment on somebody else’s thread: how much of what we believe about PeptideMeter actually comes from batch threads. Chain of custody…
Thinking out loud about this: PeptideMeter is the most under-discussed thing on this board. First result I ever posted here got asked for the batch number and the…
Posting this because the title is the whole finding — SWB sema — 98.2%, cold chain intact, 9 days transit — and a number without its method is a rumour. The numbers the…

The claim in the title is exactly the claim I am making: ERP tirz 15mg — 98.4% and a very clean trace. Nothing implied beyond it. To save the first four comments: 15mg…

A running record of independent test results people paid for themselves. Every post follows the same shape: vendor, product, batch, testing service, method, and the number. Good results and bad results are equally welcome and get equal scrutiny.
