Something I keep coming back to: the VendorInvestigate question that gets asked weekly, answered properly. Regional stock made more difference to my planning than…
Medutest
Every GLP Research Hub submission tagged to Medutest, ranked by score. Discussed in 2 communities.
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…
Title says it — FGP cagrilintide — first independent number i have seen for it — so here is the boring supporting detail that makes it worth anything. GL Biochem BPC,…
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…
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 standardspurity — 7 things I got wrong before I got it right. It is the sort of thing everyone half-believes and nobody writes down. Inter-lab variance on this assay runs…
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…
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…
The title is the argument: Janoshik — 19 things I got wrong before I got it right. Here is the rest of it. If the report gives a mass spectrum as well as UV purity, say…
someone explain PeptideMeter to me like I have not read a paper in years. Searched first, found three threads that contradict each other, hence the post. Sent a vial in…
QYB orfo — Medutest came back 99.2% against a claimed 99.0%. One vial, one service, one member paying, which is the only kind of result this board should treat as…
18th independent test on GL Biochem — 99.5% on a claimed 99.0%, and the trend is the interesting part, and before anyone asks: same batch throughout, single submission,…
Right: split one vial across Janoshik and Medutest — 99.2% and 98.9%. I paid for this one myself, nobody sent me anything, and the receipts are in the comments. Hard…
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…
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.netFiling this under things worth writing down: split one vial across Medutest and Janoshik — 99.3% and 98.7%. To save the first four comments: 99.3% and 98.7%.…
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…
Short version of the title, which is already short: 88% is not "basically fine" and i am tired of that reply. Longer version underneath. Figures up front so nobody has…
batch — 12 things I got wrong before I got it right. Not a hot take, just something I have not seen said plainly here. Sent a vial in specifically to check a supplier’s…
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…
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…
the vendor rule is doing its job and people should stop complaining. Nothing about this affects the ranking maths, before anyone asks. What "documentation" actually…
