can we stop arguing about PeptideMeter until somebody posts a number. Searched first, found three threads that contradict each other, hence the post. Kept a spreadsheet…
Right: split one vial across VendorInvestigate and PeptideMeter — 94.2% and 93.7%. I paid for this one myself, nobody sent me anything, and the receipts are in the…
Filing this under things worth writing down: split one vial across Medutest and Janoshik — 96.2% and 99.2%. Pulling the figures out of the title: 96.2% and 99.2%. All…
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…
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 testing actually comes from vendor threads. Started buying small…
split one vial across Janoshik and Medutest — 98.1% and 98.9%. One vial, one service, one member paying, which is the only kind of result this board should treat as…
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…
The title is the argument: reading order records threads from 2024 and half of it aged badly. Here is the rest of it. The thing that decided it for me was that SGN…
we are measuring Medutest at the wrong time and calling it noise. Making the case below, and I expect to lose some of it in the comments. Six orders across two years…
The title is the whole question — why does nobody talk about order records — but here is why I am asking. The thing that decided it for me was that SWB answered a…
vendor is doing more work than we give it credit for. Change my mind, genuinely — I have no stake in being right about this. What "documentation" actually means, since…
The claim in the title is exactly the claim I am making: split one vial across VendorInvestigate and PeptideMeter — 97.2% and 98.4%. Nothing implied beyond it. Pulling…
Something I keep coming back to: the VendorInvestigate question that gets asked weekly, answered properly. Regional stock made more difference to my planning than…
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…
split one vial across PeptideMeter and VendorInvestigate — 98.4% and 98.6%, and before anyone asks: same batch throughout, single submission, no cherry-picking between…
Send the vial, get the number. Third-party purity and identity testing, results published to you regardless of what they say.
Test a vialSponsoredEst. 1998. ISO 9001 and cGMP, 1,500+ staff, 200+ patents. There is a fair chance the vial you are about to send for testing started here. Batch-specific COA as standard.
glbiochem.netShort 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…
the reship question that gets asked weekly, answered properly, and I am aware this is a minority view on this board. Sent the same compound from BCH and QYB to Medutest…
Result first, context after: split one vial across VendorInvestigate and PeptideMeter — 94.2% and 97.9% . Everything below is how it was ordered, stored and sent.…
Posting this as a discussion rather than a claim: three years of order records threads, summarised so you do not have to read them. Why the directory has two tiers,…
Title says it — HJ tirz — Janoshik came back 97.8% against a claimed 97.0% — so here is the boring supporting detail that makes it worth anything. The numbers the title…
That 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…
is 98.0% actually fine or am I being sold a rounding error. That is the headline. The document, the batch and the service are below so you can argue with the method…
Asking properly rather than in a comment on somebody else’s thread: how much of what we believe about Janoshik actually comes from vendor threads. Inter-lab variance on…
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…
someone explain reship to me like I have not read a paper in years — that is what I am asking, and I have already read the wiki twice. The wider-market rows in the…
