comment on [Pricing] AU pharmacy pricing, six months, three states in c/glp1aus · 1 points · 3 days ago
This. New Zealand has its own regulator and its own funding decisions and the answers genuinely differ.
comment on [Pricing] AU pharmacy pricing, six months, three states in c/glp1aus · 1 points · 3 days ago
Read the published criteria for my indication rather than asking. Twenty minutes, and it answered everything I had been guessing at.
comment on [Pricing] AU pharmacy pricing, six months, three states in c/glp1aus · 1 points · 3 days ago
Pharmacy staff name removed; the pharmacy itself can stay in a pricing post.
This is the distinction that makes the rest of the board legible.
comment on [Pricing] AU pharmacy pricing, six months, three states in c/glp1aus · 1 points · 4 days ago
Is this about registration or about subsidy?
comment on what is a COA and how do i know if it is real in c/newbiequestions · 1 points · 8 days ago
What is the actual question underneath the question? Happy to answer both.
comment on is it normal to be this scared of the first injection in c/newbiequestions · 1 points · 9 days ago
research-use-only material is not approved for human use, and that belongs in every beginner thread
comment on is it normal to be this scared of the first injection in c/newbiequestions · -3 points · 9 days ago
week two with nothing happening is normal
comment on [Caution] not approved anywhere. keep posts descriptive. in c/cagrilintide · 5 points · 21 days ago
That result is preclinical. Worth flagging, since the thread has been reading it as human data.
comment on the shortage thing finally clicked for me and I want to write it down in c/glp1aus · 1 points · 23 days ago
Australia and New Zealand are separate systems and get conflated weekly
Disagreeing with this bit: that advice predates the change in compounded arrangements.
comment on genuine question about mg/mL that I am slightly embarrassed to ask in c/reconstitution · 9 points · 1 months ago
Agreed — units are volume. Once that lands, the rest of the arithmetic is one division.
comment on help me understand New Zealand, I have read the wiki twice in c/glp1aus · 5 points · 1 months ago
That is a pharmacy-level stock issue rather than a national supply issue. They feel identical and are not.
comment on [Discussion] can we stop arguing about dead space until somebody posts a number in c/reconstitution · 3 points · 2 months ago
Correction: that gives 30 units, not what you have written. 20mg into 3mL is 6.67mg/mL and the division follows from there.
comment on [Lab] SGN cagri — VendorInvestigate came back 97.4% against a claimed 97.0% in c/cagrilintide · 11 points · 2 months ago
Small fix — amylin analogue, not a GLP-1 analogue. The whole mechanism argument changes on that word.
comment on how much of what we believe about units actually comes from dead space threads in c/reconstitution · 158 points · 3 months ago
The dead space question sent me down a rabbit hole for a week. It is a fraction of a unit and it is the same every draw.
comment on anyone else notice what is kicking in around week 47 in c/newbiequestions · 10 points · 3 months ago
Yes — nobody here is your clinician, and the good answers on this board all end with that.
comment on [Meta] proposal — a flair for co-agonism posts in c/cagrilintide · 153 points · 3 months ago
Asked a question here that turned out to be based on a mechanism confusion. Three people untangled it patiently.
comment on why does nobody talk about amylin in c/cagrilintide · 4 points · 4 months ago
Agreed that the monotherapy numbers look modest out of context and that the context is the whole story.
comment on [Discussion] units are doing more work than we give it credit for in c/reconstitution · 23 points · 5 months ago
a U-100 syringe reads 100 units to the millilitre, every time
comment on Poland: shortage, and what it actually costs here in c/glp1aus · 36 points · 5 months ago
Read the published criteria for my indication rather than asking. Twenty minutes, and it answered everything I had been guessing at.
comment on my ApoB moved and I cannot work out whether beginner is why in c/newbiequestions · 66 points · 5 months ago
Careful — that is a dosing recommendation dressed as an anecdote, and this board removes those.
comment on Poland: shortage, and what it actually costs here in c/glp1aus · 19 points · 5 months ago
Same. Private pricing varies here as much as anywhere and people assume it is fixed.
comment on [Discussion] we are measuring first time at the wrong time and calling it noise in c/newbiequestions · 1 points · 6 months ago
a COA is a certificate of analysis, the lab document for a batch
comment on [Discussion] we are measuring New Zealand at the wrong time and calling it noise in c/glp1aus · 9 points · 6 months ago
Push back: the compounded arrangements changed and the advice you are quoting predates the change.
comment on [Discussion] we are measuring New Zealand at the wrong time and calling it noise in c/glp1aus · 8 points · 6 months ago
Personal importation provisions exist, are narrow, and carry conditions. Any summary of them here should be checked against the current official wording rather than a forum post.
comment on tried week one for 12 weeks. here is what happened. in c/newbiequestions · 23 points · 7 months ago
I would not panic about that. It is on the list of ordinary first-month experiences.
comment on [Question] dead space — what am I missing here in c/reconstitution · 13 points · 7 months ago
What concentration did you actually reconstitute at, rather than what did you intend to?
comment on [Question] dead space — what am I missing here in c/reconstitution · 26 points · 7 months ago
label the vial with the date as well as the concentration
comment on [Question] dead space — what am I missing here in c/reconstitution · 100 points · 7 months ago
do the arithmetic before you reconstitute, not while holding a syringe
comment on dead space is the most under-discussed thing on this board in c/reconstitution · 36 points · 8 months ago
The arithmetic in full: concentration is mass over volume, so 5mg into 1mL gives 5mg/mL. A U-100 syringe is graduated at 100 units per millilitre, so 5mg is 5 divided by 5 millilitres, which is 100 units.
comment on [Discussion] can we stop arguing about TGA until somebody posts a number in c/glp1aus · 0 points · 10 months ago
Small fix — that is the New Zealand arrangement, and the question is about Australia.
Adding the quickest step — ask the pharmacist to check the wholesaler.
comment on [Question] the UK — has anyone got a straight answer on New Zealand in c/glp1aus · 8 points · 10 months ago
Kept the script and the receipt for a private health claim and both were requested.
comment on [Meta] proposal — a flair for New Zealand posts in c/glp1aus · 7 points · 11 months ago
What did the pharmacy quote for the private price?
comment on [Question] how do you actually verify bacteriostatic water in c/reconstitution · 2 points · 1 year ago
Small fix — a U-100 syringe is 100 units per mL. If yours is marked differently it is not U-100 and the whole calculation changes.
comment on Canada: Australia, and what it actually costs here in c/glp1aus · 96 points · 1 year ago
The compounded arrangements changed while I was mid-thread and I was arguing from a superseded position.
This is the distinction that makes the rest of the board legible.
comment on [Question] normal — what am I missing here in c/newbiequestions · 4 points · 1 year ago
Yes. The starting dose is a tolerance step. It is not supposed to do very much.
comment on is it normal to get food noise at week 47 in c/cagrilintide · 6 points · 1 year ago
Which trial and which readout?
This is the distinction that keeps this board honest — different axis, not a stronger version of the same one.
comment on reading co-agonism threads from 2024 and half of it aged badly in c/cagrilintide · 314 points · 1 year ago
Nothing containing this compound is approved as a standalone product, and research-use-only material is not approved for human use.
comment on someone explain mg/mL to me like I have not read a paper in years in c/reconstitution · 73 points · 1 year ago
Same. I got this wrong once, caught it because the units looked absurd, and have written on every vial since.
comment on CagriSema: the version I wish someone had shown me in week 1 in c/cagrilintide · 23 points · 1 year ago
the interesting data is the combination, not the monotherapy
