the reship thing finally clicked for me and I want to write it down. It is the sort of thing everyone half-believes and nobody writes down. Asked ERP for the batch…
Janoshik
Every GLP Research Hub submission tagged to Janoshik, ranked by score. Discussed in 2 communities.
The claim in the title is exactly the claim I am making: TFC BPC — Janoshik came back 98.3% against a claimed 98.0%. Nothing implied beyond it. Since the title puts…
reship — 11 things I got wrong before I got it right. Not a hot take, just something I have not seen said plainly here. Kept a spreadsheet of quoted versus actual lead…
The title is the whole question — do order records actually matter or is it forum lore at this point — but here is why I am asking. The thing that decided it for me was…
Sigma-Aldrich — certified reference materials
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 do you actually verify test results. On inter-lab disagreement, which generates more heat here…
Title says it — 5th independent test on HJ — 99.2% on a claimed 99.0%, and the trend is the interesting part — so here is the boring supporting detail that makes it…
order records are doing more work than we give it credit for. Making the case below, and I expect to lose some of it in the comments. Regional stock made more…
unpopular opinion: most of what gets said here about VendorInvestigate is guesswork — a position I have arrived at slowly and would like tested. Why the directory has…
The title is the whole question — can we stop arguing about Medutest until somebody posts a number — but here is why I am asking. What a batch record should carry: the…
help me understand Medutest, I have read the wiki twice. Searched first, found three threads that contradict each other, hence the post. A certificate with a purity…
split one vial across Janoshik and Medutest — 95.1% and 99.3%. I will put the method line and the batch identifier up front because that is what makes this checkable.…
Posting this as a discussion rather than a claim: the vendor advice in here is 3 years out of date. To save the first four comments: 3 years. The order I actually check…
Short version of the title, which is already short: split one vial across Janoshik and Medutest — 98.7% and 98.3%. Longer version underneath. Since the title puts…
proposal — a flair for Janoshik posts. Disagreement welcome, but bring a concrete alternative wording. Lead time and minimum quantity are the two facts people forget to…
Medutest results are area% by default and people keep forgetting. Two minutes of reading now saves an argument later. Independent testing is worth more than a supplied…
Janoshik Analytical — independent HPLC & mass spec
Send the vial, get the number. Third-party purity and identity testing, results published to you regardless of what they say.
Test a vialSponsoredGL Biochem (Shanghai) Ltd. — the synthesis house
Est. 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.netThe claim in the title is exactly the claim I am making: SSA BPC — Medutest came back 98.1% against a claimed 97.5%. Nothing implied beyond it. To save the first four…
The title is the whole question — how much of what we believe about purity actually comes from batch threads — but here is why I am asking. The template is vendor,…
The title is the whole question — why does nobody talk about purity — but here is why I am asking. If the report gives a mass spectrum as well as UV purity, say so.…
help me understand Janoshik, I have read the wiki twice — that is what I am asking, and I have already read the wiki twice. What "documentation" actually means, since…
the purity advice in here is 2 years out of date. Making the case below, and I expect to lose some of it in the comments. Pulling the figures out of the title: 2 years.…
SGN vs ERP on the same compound, same month — both cleared 97.0%. I will put the method line and the batch identifier up front because that is what makes this…
Thinking out loud about this: reading testing threads from 2024 and half of it aged badly. The wider-market rows in the directory carry a band and a report count and…
Right: SSA tirz — Medutest came back 98.2% against a claimed 97.5%. I paid for this one myself, nobody sent me anything, and the receipts are in the comments. The…
CPC cagri — Janoshik came back 98.1% against a claimed 97.5%. One vial, one service, one member paying, which is the only kind of result this board should treat as…
batch is the most under-discussed thing on this board — a position I have arrived at slowly and would like tested. Tested three lots over a year rather than three vials…
