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.…

13 months in and basics are still the thing I get wrong. This is a description of what happened to me and not a plan for anybody else. Figures up front so nobody has to…
the reimbursement thing finally clicked for me and I want to write it down. Making the case below, and I expect to lose some of it in the comments. Asked in my own…
Trying to get a straight answer on this: Canada — has anyone got a straight answer on carrier. Where the time actually goes, which I got wrong for two years. Total…
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 standardsSomething 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…
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…
The title is the argument: reading SURMOUNT threads from 2024 and half of it aged badly. Here is the rest of it. Discontinuation rates are a tolerability result. A…
The title is the argument: we are measuring LC-MS at the wrong time and calling it noise. Here is the rest of it. SWB sent me the column, the gradient and the…
The title is the whole question — can we stop arguing about titration until somebody posts a number — but here is why I am asking. Dropped my injection day by two days…
three years of Janoshik threads, summarised so you do not have to read them — a position I have arrived at slowly and would like tested. Tested three lots over a year…
The title is the whole question — how much of what we believe about area percent actually comes from COA threads — but here is why I am asking. Started keeping a folder…
how much of what we believe about PeptideMeter actually comes from test results threads. I would rather ask a basic question now than get this wrong quietly for two…
REDEFINE 1 — what cagri adds on top of sema. It is the sort of thing everyone half-believes and nobody writes down. Asked a question here that turned out to be based on…
Posting this as a discussion rather than a claim: the insulin syringe question that gets asked weekly, answered properly. Why "more water" keeps confusing people,…
Trying to get a straight answer on this: below spec — what am I missing here. Chain of custody is why member-funded testing is worth more than a supplied certificate:…
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.netsmall win: goal weight stopped being a problem at week 85. Numbers below. Ask me the boring questions, they are the useful ones. Withdrawal studies in this class…
evidence levels: in vitro, rodent, human. say which one you mean — with the reasoning, because a rule without a reason gets ignored. Sent an unusual compound to…
the province question that gets asked weekly, answered properly. It is the sort of thing everyone half-believes and nobody writes down. Kept every form and reference…
Asking properly rather than in a comment on somebody else’s thread: someone explain concentration to me like I have not read a paper in years. Shook the first vial…
what would you tell week-1 you about ACHIEVE. I would rather ask a basic question now than get this wrong quietly for two months. Because it is not a peptide, it is not…
Short version of the title, which is already short: split one vial across VendorInvestigate and PeptideMeter — 98.6% and 98.4%. Longer version underneath. Figures up…
week 52 check-in — 14kg down, reflux manageable, one thing confusing me, and the part I actually want to talk about is at the bottom. Pulling the figures out of the…
New Zealand is doing more work than we give it credit for, which sounds obvious until you try to state the evidence for it. The compounded arrangements changed while I…
can we stop arguing about stopped until somebody posts a number. I am not trying to be the "source?" guy. I would just like a source. Fridge died in a heatwave and I…
help me understand Wegovy, I have read the wiki twice. I would rather ask a basic question now than get this wrong quietly for two months. Steady state after a dose…
