comment on [Private Rx] the online consultation asked me nothing. that is not safe. in c/glp1uk · 6 points · 3 days ago

the price difference between pharmacies this month is genuinely large

comment on ApoB over LDL-C and i will keep saying it in c/bloodwork · 23 points · 3 days ago

My fasting insulin moved and I spent a fortnight convinced I knew why. The repeat six weeks later was back in range and I had changed nothing.

comment on [Country] SE/NO/DK — Norway is the outlier and not in a good way in c/glp1eu · 2 points · 9 days ago

Kept the prescription and the receipt for a claim, purely because a thread here told me to. Both were requested.

comment on [Pricing] £129 to £189 for the same thing across four pharmacies this month in c/glp1uk · 6 points · 9 days ago

Four pharmacies, four prices, same product, same month. The spread was larger than I expected and none of them were the headline offer.

Assumed a prescription would be honoured across the border. It was not, and the rules are clear once you actually read them.

comment on [Data] my fridge is 2.1°C at the back and 7.8°C in the door. same fridge. in c/coldchain · 9 points · 12 days ago

Agreed. The dry powder is the robust state; it is the solution that needs the care.

comment on [Explainer] which labs are worth repeating quarterly and which are theatre in c/bloodwork · 4 points · 22 days ago

one measurement is a point, two is a line, three is a trend

comment on [Explainer] excursion tables, and why "it got warm" is not a data point in c/coldchain · 1 points · 22 days ago

Ordered from the warehouse in Sweden instead of origin and the transit went from a fortnight to 10 days. Entirely different proposition in August.

comment on how much of what we believe about reimbursement actually comes from EMA threads in c/glp1eu · 13 points · 1 months ago

What pack size is that price for?

comment on [Discussion] the formulary advice in here is 2 years out of date in c/glp1canada · 3 points · 1 months ago

the exception drug status route exists in several provinces

comment on [Discussion] cold chain is doing more work than we give it credit for in c/coldchain · 63 points · 1 months ago

Kept a vial at room temperature for eleven days by accident. Tested it out of guilt. It was fine.

permalink

comment on the ApoB question that gets asked weekly, answered properly in c/bloodwork · 1 points · 1 months ago

Time of day, fasting state, hydration and recent exercise all move common markers.

Adding the obvious one — take it to whoever ordered the panel. This board cannot read it for you.

comment on [Discussion] we are measuring A1c at the wrong time and calling it noise in c/bloodwork · 9 points · 1 months ago

assay method matters, especially between different labs

permalink

comment on Canada is the most under-discussed thing on this board in c/glp1canada · 10 points · 1 months ago

I would not read one pharmacy’s cash price as the going rate. The spread is real.

permalink

comment on stalled for 15 weeks at 2.5mg and I refuse to panic this time in c/glp1women · 1 points · 2 months ago

hair shedding follows the rate of loss, not the compound

permalink

comment on [Discussion] can we stop arguing about NHS until somebody posts a number in c/glp1uk · 10 points · 2 months ago

the MHRA supply notices are published, read them before the panic threads

permalink

comment on someone explain insulin resistance to me like I have not read a paper in years in c/glp1women · -25 points · 2 months ago

I would not read one person’s cycle-linked experience as a general pattern. The variation here is enormous.

permalink

comment on [PSA] cold chain is not what most of this community thinks it is in c/coldchain · 51 points · 2 months ago

Small fix — refrigerated, not frozen, once it is in solution.

permalink

comment on [Discussion] the pricing advice in here is 2 years out of date in c/glp1uk · 71 points · 2 months ago

Cosigning on discharge at goal. It catches people who have done everything right and did not know it was coming.

permalink

comment on my triglycerides moved and I cannot work out whether cycle is why in c/glp1women · 8 points · 3 months ago

symptom patterns can track the cycle rather than the dose

permalink

comment on [Meta] the ALT rule is doing its job and people should stop complaining in c/bloodwork · 12 points · 3 months ago

draw at the same point in the week if you want comparability

permalink

comment on [Question] Canada — what am I missing here in c/glp1canada · 10 points · 3 months ago

Correction: that is regulatory approval, not coverage. They are separate decisions by separate bodies.

permalink

comment on someone explain baseline labs to me like I have not read a paper in years in c/bloodwork · 71 points · 3 months ago

Have you taken this to whoever ordered it?

permalink

comment on does pricing actually matter or is it forum lore at this point in c/glp1uk · 21 points · 3 months ago

Small fix — that is the Scottish pathway. The post is asking about England and the answer is different.

permalink

comment on [Discussion] we are measuring PCOS at the wrong time and calling it noise in c/glp1women · 0 points · 4 months ago

That trial did not enrol the population you are asking about, so it cannot answer this.

permalink

comment on [Results] 86 weeks on 10mg, full numbers, ask me anything boring in c/bloodwork · -29 points · 4 months ago

nothing on this board interprets your results for you

permalink

comment on how much of what we believe about eGFR actually comes from ferritin threads in c/bloodwork · 134 points · 5 months ago

Nobody here can interpret your panel and this comment is not doing so. What a board can usefully do is help you ask better questions of somebody who can.

permalink

comment on why does nobody talk about pharmacy in c/glp1eu · 15 points · 5 months ago

Correction: that is the authorisation position, and the question was about reimbursement. Different bodies, different answers.

permalink

comment on three years of MHRA threads, summarised so you do not have to read them in c/glp1uk · 50 points · 5 months ago

ask the pharmacy for the price list, not the headline offer

permalink

comment on reading excursion threads from 2024 and half of it aged badly in c/coldchain · 6 points · 5 months ago

Ordered from the warehouse in France instead of origin and the transit went from a fortnight to 8 days. Entirely different proposition in August.

permalink

comment on [Discussion] we are measuring NHS at the wrong time and calling it noise in c/glp1uk · 10 points · 6 months ago

Same. My ICB threshold was different from the neighbouring one and nobody could tell me why.

permalink

comment on my TSH moved and I cannot work out whether ferritin is why in c/bloodwork · 55 points · 6 months ago

fasting state and time of day change more than people expect

permalink

comment on [Question] France — has anyone got a straight answer on EU in c/glp1eu · 1 points · 6 months ago

That shortage notice was national and does not apply where the question is coming from.

permalink

comment on genuine question about ApoB that I am slightly embarrassed to ask in c/bloodwork · 47 points · 7 months ago

Careful — that is a question for whoever ordered the panel, and nobody in this thread can answer it responsibly.

permalink

comment on [Question] how do you actually verify province in c/glp1canada · 1 points · 7 months ago

Yes. Cash prices vary and comparing them before assuming coverage is the only route is worth doing.

permalink

comment on [Question] how do you actually verify province in c/glp1canada · -7 points · 7 months ago

Nothing here is medical or legal advice. The pharmacist and the prescriber are the people who can act, and both are faster than a forum.

permalink

comment on genuine question about ALT that I am slightly embarrassed to ask in c/bloodwork · 8 points · 8 months ago

Yes. Repeat before you react. Almost every alarming single value I have posted here regressed on the repeat.

permalink

comment on [Discussion] ApoB is doing more work than we give it credit for in c/bloodwork · 3 points · 8 months ago

Substantial weight loss independently moves lipids, liver enzymes and several other markers. Attributing a change to a compound while losing weight is confounded by design.

the Irish scheme cap is the single most useful fact in this board

comment on how much of what we believe about MHRA actually comes from pharmacy threads in c/glp1uk · 73 points · 9 months ago

Concentrations can differ between products and between pharmacies. Switching mid-titration means redoing the arithmetic rather than carrying the old unit count across.
