Independent testing, order records and receipts. Claims need evidence.
Six orders from JEEP over about fourteen months. Guangzhou to Manchester every time. Nothing has gone wrong. Not one thing. Which is genuinely making me nervous,…
1,100-odd COAs in my folder structure. Sorted by vendor, then compound, then batch. I do this instead of having hobbies. Here is a pattern I did not expect: water…
Package went missing between Zhuhai and here. Tracking died in a transit hub and stayed dead for eleven days. Sent one email with a screenshot of the dead tracking page…
Xi'an, five orders, roughly a year. Two things are true simultaneously and I have stopped trying to reconcile them. The material: fine every time. Two independent…
Vendor-level purity averages over time, built from independent results rather than vendor claims. Transparent methodology, open dataset.
Browse resultsThat is the entire event. They said eighteen days. It took seventeen. I want to talk about why this feels remarkable, because it should not. Eleven of twelve member…
Genuine methodology question rather than a vendor post, so flairing it Discussion. My rule has been three independent results, from at least two different members,…
Writing this up properly: KP reship policy actually honoured — receipts inside. I keep a table for exactly this reason. Paradigm Peptide came up in three threads the…
same batch number showing up at two unrelated vendors. that is not a coincidence — a position I have arrived at slowly and would like tested. Started buying small…
WXT order #4 — 8 days Wuxi to UK, cold pack still solid. Posting it because I searched for this exact thing before ordering and found nothing useful. 8 days — those are…
Trying to get a straight answer on this: how many independent tests before you trust a vendor. my number is three. Inter-lab variance on this assay runs a point or two…
a vendor-supplied COA is a marketing document until someone else agrees with it. It comes up every few weeks and the answer has not changed. Inter-lab variance on this…
Writing this up properly: BCH — twelve certificates, twelve with batch, date, method and water content. I keep a table for exactly this reason. What "documentation"…
Posting this as a discussion rather than a claim: the "our facility" photo on half these sites reverse-searches to a stock library. Started buying small deliberately,…
we should require batch numbers in every vendor post title. Change my mind, genuinely — I have no stake in being right about this. What "documentation" actually means,…
Title is the summary — JEEP six orders in, zero problems, and i am suspicious of my own luck — and the detail is below in the order it happened. Started buying small…
Reference standards, analytical reagents and system-suitability material. If you are running your own method, start with a known.
Reference standardsdomain registered eleven days ago, 400 five-star reviews. sure. It is the sort of thing everyone half-believes and nobody writes down. Kept a spreadsheet of quoted…
Adding to the record: CPC — 2001 establishment date checks out against the company registry. It matches what the source page already shows, for whatever that is worth.…
why do vendor accounts always have the same three typos. If this has been answered properly somewhere, link me and I will delete. Core Peptides came up in three threads…
Short report. TFC quoted 11 days to Eastern Canada and hit it four times running. Dates and lane below. Figures up front so nobody has to dig: 11 days. The wider-market…
Writing this up properly: the QST batch dispute — vendor retested, numbers matched, my error. I keep a table for exactly this reason. The wider-market rows in the…
MKM — five tests, four compounds, nothing outside the band. If anybody has the same lane and a different experience I would genuinely like to see it next to mine. A…
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…
"lab tested" with no lab named is not a claim. Change my mind, genuinely — I have no stake in being right about this. Core Peptides came up in three threads the week I…
Adding to the record: SGN is a real company with real catalogue chemistry and people still doubt it. It matches what the source page already shows, for whatever that is…
group buy organiser vanished with 3.4k. here is the timeline. It is the sort of thing everyone half-believes and nobody writes down. Kept a spreadsheet of quoted versus…
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.
Independent HPLC and mass spec. The number you get is the number they found.
janoshik.comSponsoredCustom peptides and amino acids direct from the manufacturer since 1998. ISO 9001 / cGMP. Batch COA every order.
