special authorization is the most under-discussed thing on this board. I have gone back and forth on this for months. Quantity limits restrict how much may be dispensed…

comment on [Method] the gradient everyone uses for sema and why it under-resolves the des-amido in c/hplc · 1 points · 3 days ago
Agreed.
Adding one practical thing — run the blank. It answers this before anyone has to argue about it.
comment on [Delay] two weeks in a transit hub, then delivered fine in c/intlshipping · 29 points · 3 days ago
Disagree. That is a customs hold, not a carrier delay, and lumping them together makes the lane table wrong.
comment on [Lab] SSA tirz 10mg — Janoshik 99.1%, third batch in a row in c/tirzepatide · 2 points · 4 days ago
Cosigning the four-week thing. It is a minimum interval, and treating it as a schedule to keep up with is how people end up miserable at 12.5.
comment on [Question] does anyone have the special authorisation criteria in writing in c/glp1canada · 9 points · 6 days ago
Formulary criteria are revised, and plan renewal is a natural point at which a previously refused request may succeed without anything about the applicant changing.
comment on [Explainer] integration decisions change your number more than the sample does in c/hplc · 11 points · 7 days ago
Disagree. Inter-lab spread of a point or two on this assay is ordinary and calling it a discrepancy misleads people.
comment on GIP agonism explained like i am five, please in c/tirzepatide · 5 points · 10 days ago
This matches mine. Milder nausea than I expected, and what there was settled inside a fortnight of each step.
comment on help me understand Canada, I have read the wiki twice in c/glp1canada · 1 points · 11 days ago
say the province or the answers will be wrong
comment on [Data] packaging quality by vendor, scored on five things, 60 shipments in c/intlshipping · 2 points · 21 days ago
Correction: that was clearance time, not carrier time.
Disagreeing with this bit: a single slow shipment does not move a lane, it joins the distribution.
comment on compounded tirz pricing has doubled in my area in four months in c/tirzepatide · 89 points · 23 days ago
Appetite effect for me is flat across seven days. On sema it was a wave. Same person, different molecule.
comment on [Discussion] we are measuring tirzepatide at the wrong time and calling it noise in c/tirzepatide · 49 points · 1 months ago
The distribution matters more than the mean. In the trial population the interquartile spread was wide enough that two honest people can have completely different runs on the same arm.
comment on why does nobody talk about SURPASS in c/tirzepatide · 188 points · 1 months ago
the appetite effect is blunter than sema, in a good way, most weeks
comment on reading LC-MS threads from 2024 and half of it aged badly in c/hplc · 1 points · 1 months ago
Same view — reporting the gradient is what makes a result checkable rather than merely stated.
comment on Canada is the most under-discussed thing on this board in c/glp1canada · 44 points · 1 months ago
the exception drug status route exists in several provinces
comment on [PSA] chromatogram is not what most of this community thinks it is in c/hplc · 69 points · 2 months ago
area percent is relative to what the detector saw and nothing else
comment on [Question] France — has anyone got a straight answer on shipping in c/intlshipping · 7 points · 2 months ago
Right, and the last mile is where my variance has always come from, not the international leg.
comment on [Discussion] we are measuring Zepbound at the wrong time and calling it noise in c/tirzepatide · 1 points · 2 months ago
The 21% figure is a 72-week mean on the highest arm. Quoting it as what someone should expect by week 7 is not a fair reading.
comment on small win: Mounjaro stopped being a problem at week 45 in c/tirzepatide · 10 points · 2 months ago
The distribution matters more than the mean. In the trial population the interquartile spread was wide enough that two honest people can have completely different runs on the same arm.
comment on help me understand packaging, I have read the wiki twice in c/intlshipping · 107 points · 3 months ago
origin, destination, carrier, month — post all four or the report is noise
comment on [Meta] the LC-MS rule is doing its job and people should stop complaining in c/hplc · 4 points · 3 months ago
Started reporting my own integrations with the baseline choice stated. Arguments in my threads dropped by about half.
comment on [Results] 45 weeks, 14kg, and tirzepatide was the hard part in c/tirzepatide · 58 points · 3 months ago
Push back: "gentler than sema" is a population statement. Plenty of people on this board have the opposite experience and they are not doing it wrong.
comment on how much of what we believe about private plan actually comes from Canada threads in c/glp1canada · 95 points · 4 months ago
A rejected claim at the pharmacy counter and a denied authorization are different events with different remedies.
Disagreeing with this line: that is an employer plan process and the provincial one differs.
comment on [Results] 26 weeks, 9kg, and dual agonist was the hard part in c/tirzepatide · 148 points · 4 months ago
Yes. I stepped to 12.5 because the calendar said so, not because anything needed fixing, and I regretted it for a fortnight.
comment on Canada: Canada, and what it actually costs here in c/glp1canada · 2 points · 5 months ago
employer plans have their own criteria and their own appeals
comment on Canada: Canada, and what it actually costs here in c/glp1canada · 6 points · 5 months ago
Employer-sponsored plans have their own criteria and appeal processes, independent of the provincial formulary. Which one applies determines everything about the route.
comment on [Meta] proposal — a flair for HPLC posts in c/hplc · 19 points · 6 months ago
Agreed, and it is why Homopeptide printing the column and gradient on the certificate is genuinely useful rather than decorative.
comment on [Meta] proposal — a flair for 15mg posts in c/tirzepatide · 13 points · 6 months ago
Does fatigue follow the day after the shot, or is it spread across the week?
comment on [Meta] the Zepbound rule is doing its job and people should stop complaining in c/tirzepatide · 19 points · 7 months ago
the trials titrated on a calendar, real people titrate on symptoms
comment on tirzepatide — 9 things I got wrong before I got it right in c/tirzepatide · 20 points · 7 months ago
Small fix: SURMOUNT is the obesity programme, SURPASS is the type-2 programme. They are different endpoints and the numbers do not transfer.
comment on [Discussion] we are measuring SURPASS at the wrong time and calling it noise in c/tirzepatide · 3 points · 8 months ago
The step schedule question, answered properly, because it comes up weekly.
This. The step interval is a floor, and reading it as a timetable is the most expensive mistake in the thread.
comment on [Question] is 99.3% actually fine or am I being sold a rounding error in c/tirzepatide · -16 points · 9 months ago
the trials titrated on a calendar, real people titrate on symptoms
comment on [Results] 74 weeks, 23kg, and GIP was the hard part in c/tirzepatide · 1 points · 10 months ago
Have you held a step for longer than the four-week minimum at any point?
comment on special authorization is the most under-discussed thing on this board in c/glp1canada · 24 points · 11 months ago
Those criteria were revised at renewal, so the version quoted upthread is out of date.
comment on special authorization is the most under-discussed thing on this board in c/glp1canada · 61 points · 11 months ago
Small fix — that formulary position is another province’s and does not apply here.
comment on special authorization is the most under-discussed thing on this board in c/glp1canada · 1 points · 11 months ago
Which province?
comment on [PSA] special authorization is not what most of this community thinks it is in c/glp1canada · 2 points · 11 months ago
Spent three weeks on what turned out to be a quantity limit rather than a coverage question.
comment on reading purity threads from 2024 and half of it aged badly in c/hplc · 102 points · 1 year ago
System suitability — repeat injections, tailing factor, plate count, RSD on area — is what tells you the instrument was fit for the measurement that day. Without it, the purity figure is unanchored.
comment on someone explain HPLC to me like I have not read a paper in years in c/hplc · 163 points · 1 year ago
Ran a blank after a high-concentration injection and found the carryover I had been calling an impurity.
comment on [Question] how do you actually verify shipping in c/intlshipping · 151 points · 1 year ago
Careful — the supplier does not control the last mile and most of your variance is in it.
comment on integration — 22 things I got wrong before I got it right in c/hplc · 656 points · 1 year ago
Yes. Retention time is a hypothesis about identity. Mass is the answer.
