PeptideMeter

below spec is doing more work than we give it credit for. Change my mind, genuinely — I have no stake in being right about this. First result I ever posted here got…

Asking properly rather than in a comment on somebody else’s thread: why does nobody talk about test results. Tested three lots over a year rather than three vials from…

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…

Something I keep coming back to: we are measuring test results at the wrong time and calling it noise. Split one vial between Janoshik and VendorInvestigate. The two…

we are measuring below spec at the wrong time and calling it noise — a position I have arrived at slowly and would like tested. On inter-lab disagreement, which…

Asking properly rather than in a comment on somebody else’s thread: how much of what we believe about Medutest actually comes from batch threads. Tested three lots over…

Janoshik results are area% by default and people keep forgetting — with the reasoning, because a rule without a reason gets ignored. Eternal Peptides came up in three…

Asking properly rather than in a comment on somebody else’s thread: can we stop arguing about below spec until somebody posts a number. On inter-lab disagreement, which…

the Janoshik rule is doing its job and people should stop complaining — posting the reasoning in public because a policy you cannot inspect is just a preference. Tested…

Janoshik is the most under-discussed thing on this board, which sounds obvious until you try to state the evidence for it. What a batch record should carry: the lot…

the PeptideMeter rule is doing its job and people should stop complaining. Nothing about this affects the ranking maths, before anyone asks. Core Peptides came up in…

how much of what we believe about Janoshik actually comes from PeptideMeter threads — that is what I am asking, and I have already read the wiki twice. What…

help me understand reship, I have read the wiki twice — that is what I am asking, and I have already read the wiki twice. Hangzhou Meite Bio came up in three threads…

the PeptideMeter advice in here is 2 years out of date. Making the case below, and I expect to lose some of it in the comments. To save the first four comments: 2…

we are measuring batch at the wrong time and calling it noise — a position I have arrived at slowly and would like tested. On inter-lab disagreement, which generates…

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.…

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…

Proposal, not a decision: proposal — a flair for Medutest posts. If the report gives a mass spectrum as well as UV purity, say so. Identity and relative quantity are…

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…

Right: Homopeptide vs QSC on the same compound, same month — both cleared 98.0%. I paid for this one myself, nobody sent me anything, and the receipts are in the…

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…

Asking 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…
