comment on the step therapy question that gets asked weekly, answered properly in c/insurancefights · 1 points · 1 year ago
Spent six weeks arguing in general terms and got nowhere. Two paragraphs quoting their own criteria turned it around in eleven days.
comment on [Question] Canada — has anyone got a straight answer on EMA in c/glp1eu · 6 points · 1 year ago
Pack sizes and presentations differ between member states, so a headline price is not comparable until it is normalised to a common quantity.
comment on [Question] is 99.2% actually fine or am I being sold a rounding error in c/hplc · 5 points · 1 year ago
Push back: a longer run is not automatically better resolution. You are trading peak width for time and the ratio is what matters.
comment on how much of what we believe about API source actually comes from telehealth threads in c/compounding · 29 points · 1 year ago
Agreed on potency testing of the finished preparation. That is a different question from the purity of the starting material.
comment on why does nobody talk about Zepbound in c/tirzepatide · 869 points · 1 year ago
Came off sema and onto tirz with a two-week gap. The first month was flat and I assumed I had made a mistake. Month two it moved.
comment on [Lab] WXT cagri — PeptideMeter came back 97.8% against a claimed 97.0% in c/hplc · 273 points · 1 year ago
Sent the same vial to PeptideMeter and VendorInvestigate. 99.1% against a claimed 98.5%. The difference was the gradient, not the material.
comment on jurisdiction — 14 things I got wrong before I got it right in c/customs · 1 points · 1 year ago
Cosigning on paperwork. The boring documents are the ones that matter when a process starts.
comment on shortage is the most under-discussed thing on this board in c/glp1aus · 6 points · 1 year ago
This. New Zealand has its own regulator and its own funding decisions and the answers genuinely differ.
comment on [Discussion] we are measuring Mounjaro at the wrong time and calling it noise in c/tirzepatide · 457 points · 1 year ago
the four-week step schedule is the label, not folklore
comment on [Discussion] we are measuring Mounjaro at the wrong time and calling it noise in c/tirzepatide · 622 points · 1 year ago
34kg over 83 weeks, never went past 10mg, and injection-site soreness stayed mild the whole way. Posting because the loud threads are all 15mg.
comment on [Meta] proposal — a flair for appeal posts in c/insurancefights · 7 points · 1 year ago
ask for the denial reason in writing, always
comment on [Lab] split one vial across Janoshik and Medutest — 98.7% and 98.3% in c/hplc · 7 points · 1 year ago
I would not blame the sample yet. Everything you have described is consistent with the column rather than the vial.
comment on [Discussion] reship is doing more work than we give it credit for in c/intlshipping · 5 points · 1 year ago
Ordered from the warehouse in Denmark instead of origin and the whole customs question disappeared. 10 days, door to door.
comment on [Discussion] reship is doing more work than we give it credit for in c/intlshipping · 6 points · 1 year ago
Small fix — shipped from the regional warehouse, not from origin, which is why the number looks unusual.
comment on import is the most under-discussed thing on this board in c/customs · 1 points · 1 year ago
What does the notice actually say, in its own words?
comment on [Question] chromatogram — what am I missing here in c/hplc · 138 points · 1 year ago
Mass spectrometry answers identity. UV purity answers relative quantity under the run conditions. A document with one and not the other is answering half the question, and the half it answers should be stated.
comment on France: appeal, and what it actually costs here in c/insurancefights · 76 points · 1 year ago
Right, and keeping every date and reference number turns a frustrating process into an auditable one.
comment on jurisdiction — 3 things I got wrong before I got it right in c/customs · 124 points · 1 year ago
Disagree — that is the position in one country and this thread is about another. They are genuinely different.
comment on [Lab] split one vial across PeptideMeter and VendorInvestigate — 96.8% and 99.1% in c/hplc · 429 points · 1 year ago
That figure cannot be quoted to two decimals off that baseline. The precision is not in the data.
comment on how much of what we believe about dual agonist actually comes from GIP threads in c/tirzepatide · 134 points · 1 year ago
2.5mg is a four-week starting dose, not a maintenance dose. Worth being precise since people search these threads.
comment on three years of 503A threads, summarised so you do not have to read them in c/compounding · 355 points · 1 year ago
Potency and sterility testing on the finished preparation are separate from any certificate covering the starting material. Ask which you are being shown.
comment on [Results] 47 weeks, 15kg, and GIP was the hard part in c/tirzepatide · 34 points · 1 year ago
2.5mg is a four-week starting dose, not a maintenance dose. Worth being precise since people search these threads.
comment on [Results] 47 weeks, 15kg, and GIP was the hard part in c/tirzepatide · 1 points · 1 year ago
the fatigue profile is genuinely gentler than people expect coming from sema
comment on [Results] 47 weeks, 15kg, and GIP was the hard part in c/tirzepatide · -19 points · 1 year ago
Sulphur burps for the first eight days after each step, then nothing. Predictable enough that I planned my week around it.
comment on the prescription thing finally clicked for me and I want to write it down in c/glp1eu · 17 points · 1 year ago
cross-border prescription rules exist and they are narrower than people think
comment on how much of what we believe about appeal actually comes from step therapy threads in c/insurancefights · 86 points · 1 year ago
Internal appeals are decided by the plan.
Disagreeing with this line: the deadline runs from the letter date and treating it otherwise is expensive.
comment on why does nobody talk about 503A in c/compounding · 61 points · 1 year ago
the price difference is mostly the intake, not the vial
comment on [Discussion] LC-MS is doing more work than we give it credit for in c/hplc · 11 points · 1 year ago
baseline choice is a decision, not a measurement
comment on [Discussion] can we stop arguing about GIP until somebody posts a number in c/tirzepatide · -14 points · 1 year ago
Pen or vial? The step sizes available differ and it changes this answer.
comment on what changed for me between month 6 and month 14 in c/tirzepatide · 551 points · 1 year ago
Does fatigue follow the day after the shot, or is it spread across the week?
comment on [PSA] telehealth is not what most of this community thinks it is in c/compounding · 143 points · 1 year ago
Cosigning the beyond-use date question.
Disagreeing with this bit: registration is not equivalence, and the two get run together constantly.
comment on someone explain LC-MS to me like I have not read a paper in years in c/hplc · 3 points · 1 year ago
Same method at both labs, or two different gradients?
This is the whole methodological point of the board in one line.
comment on [Question] how do you actually verify Mounjaro in c/tirzepatide · 1 points · 1 year ago
Correction to my own post above — I said 5mg and I have been on 7.5mg since the spring.
kaia_cabrera is right that the two molecules are not interchangeable. There is no published conversion and the ones circulating are invented.
comment on the reimbursement thing finally clicked for me and I want to write it down in c/glp1eu · 595 points · 1 year ago
Pharmacy margins and dispensing fees are regulated nationally, which explains price differences that otherwise look arbitrary.
comment on genuine question about HPLC that I am slightly embarrassed to ask in c/hplc · 154 points · 1 year ago
baseline choice is a decision, not a measurement
comment on [Discussion] the formulary advice in here is 3 years out of date in c/insurancefights · 1 points · 1 year ago
the second-level appeal is where things actually turn
comment on [Question] declared value — what am I missing here in c/customs · 2 points · 1 year ago
Research-use-only labelling is a description of intended use, not a customs classification.
Adding the standing caveat — nothing here is legal advice and this one genuinely warrants somebody qualified.
comment on 15mg — my 12-week log, condensed into one table in c/tirzepatide · -14 points · 1 year ago
2.5 is the starter dose and it is not meant to be the dose that works
comment on the appeal thing finally clicked for me and I want to write it down in c/insurancefights · 82 points · 1 year ago
step therapy is a documentation problem, not an argument
comment on [Discussion] dual agonist is doing more work than we give it credit for in c/tirzepatide · 1 points · 1 year ago
Yes — 10mg being a genuine landing place for a lot of people is underrated. There is no medal for 15.
