comment on [Explainer] delayed gastric emptying does most of the work people credit to the brain in c/glp1science · 1 points · 2 days ago

What does the discussion section say about the limitation you are glossing?

comment on [Delay] two weeks in a transit hub, then delivered fine in c/intlshipping · 16 points · 4 days ago

a lane with four reports is not yet a lane

permalink

comment on i stopped eating at 70% full and the vomiting stopped entirely in c/sideeffects · 39 points · 4 days ago

Nothing in this thread is medical advice, including this comment. I am describing a mechanism, not telling anybody what to do about their own week.

comment on [PSA] no tracking numbers. they identify both ends. removed on sight. in c/intlshipping · 12 points · 4 days ago

I would not read a single slow shipment as a lane change. Post it and let the median move if it is real.

comment on reflux got worse for three weeks then better than baseline in c/sideeffects · 149 points · 9 days ago

The effect on gastric emptying is most pronounced early and attenuates with continued dosing, which is the mechanism behind the "it settles at a stable dose" pattern the whole board reports.

permalink

comment on [Discussion] the compounding gap was a symptom, not a solution in c/compounding · -17 points · 12 days ago

Careful. Naming a clinic without describing what actually happened turns this into a different kind of thread.

permalink

comment on [Paper] amylin co-agonism is genuinely different pharmacology, not just more GLP-1 in c/glp1science · 242 points · 16 days ago

What was the exposure in that experiment relative to therapeutic?

permalink

comment on [Explainer] the four things a COA must have or it is decorative in c/coa · 176 points · 16 days ago

Correction: that is net peptide content, not purity. Different number, different meaning, and the document says so if you read the row label.

comment on freezing reconstituted product: why the answer is no in c/coldchain · 100 points · 19 days ago

the door shelf is the worst place in the fridge

comment on freezing reconstituted product: why the answer is no in c/coldchain · 27 points · 19 days ago

I would not freeze it in solution.

This is the distinction that resolves most threads here — powder and solution are different problems.

permalink

comment on my gallbladder came out at month 7 and i would still do it again in c/sideeffects · 86 points · 22 days ago

Nothing in this thread is medical advice, including this comment. I am describing a mechanism, not telling anybody what to do about their own week.

permalink

comment on [Explainer] excursion tables, and why "it got warm" is not a data point in c/coldchain · 15 points · 22 days ago

Once in solution, the relevant risks are hydrolysis, aggregation and, for some sequences, oxidation. Refrigeration slows all three; freezing a solution introduces a separate risk at the ice interface.

permalink

comment on [Meta] proposal — a flair for FLOW posts in c/trialwatch · 13 points · 23 days ago

Yes — the interval is the finding. A point estimate with a wide interval is a hypothesis in a nice font.

permalink

comment on [COA] full document, nothing cropped, tell me what i am missing in c/coa · 4 points · 29 days ago

identity and quantity are two questions and most documents answer one

permalink

comment on [COA] full document, nothing cropped, tell me what i am missing in c/coa · 7 points · 29 days ago

net peptide content and purity are two different numbers on the same vial

permalink

comment on shipping is the most under-discussed thing on this board in c/intlshipping · 6 points · 1 months ago

Same.

This is why the lane table is organised the way it is. The supplier is not the unit.

permalink

comment on unpopular opinion: most of what gets said here about gastric emptying is guesswork in c/glp1science · 11 points · 1 months ago

That study was in a rodent model. Worth stating, since the thread has been reading it as human data.

permalink

comment on someone explain lyophilised to me like I have not read a paper in years in c/coldchain · 19 points · 1 months ago

Once in solution, the relevant risks are hydrolysis, aggregation and, for some sequences, oxidation.

This is the distinction that resolves most threads here — powder and solution are different problems.

comment on someone explain lyophilised to me like I have not read a paper in years in c/coldchain · 1 points · 1 months ago

Gel packs are designed for a duty cycle. A liquid pack at the end of a longer-than-expected transit is a pack behaving as specified, not evidence of an excursion in the vial.

permalink

comment on [Meta] the FLOW rule is doing its job and people should stop complaining in c/trialwatch · 7 points · 1 months ago

Careful with that mean. The distribution around it was wide enough that it describes very few individual participants.

permalink

comment on [Discussion] can we stop arguing about import until somebody posts a number in c/customs · -38 points · 1 months ago

ask the supplier what documentation accompanies the shipment

permalink

comment on [Meta] proposal — a flair for carrier posts in c/intlshipping · 4 points · 1 months ago

Total transit decomposes into first mile, international leg, clearance and last mile. Only the first two are meaningfully under the shipper’s control and most reported variance sits in the last two.

permalink

comment on [Question] New Zealand — has anyone got a straight answer on prescription in c/glp1eu · 19 points · 1 months ago

the same product has different names and pack sizes across the union

permalink

comment on [Discussion] we are measuring jurisdiction at the wrong time and calling it noise in c/customs · 2 points · 1 months ago

Disagree — that is the position in one country and this thread is about another. They are genuinely different.

permalink

comment on the UK: excursion, and what it actually costs here in c/coldchain · 1 points · 1 months ago

a logger costs less than a vial and answers the question permanently

permalink

comment on [Meta] the 503A rule is doing its job and people should stop complaining in c/compounding · 8 points · 1 months ago

Yes. The shortage list is the legal hinge for the whole arrangement and its status is public.

permalink

comment on [Meta] the 503A rule is doing its job and people should stop complaining in c/compounding · 20 points · 1 months ago

potency testing on the finished preparation is the thing to ask for

permalink

comment on how much of what we believe about area percent actually comes from COA threads in c/coa · 129 points · 1 months ago

Same view. SSA prints the column and the gradient, which means somebody could actually reproduce the run.

permalink

comment on [Question] is 98.4% actually fine or am I being sold a rounding error in c/semaglutide · 2 points · 1 months ago

Weight change and appetite change are different endpoints on different timescales. Conflating them is where most of the confusion on this board starts.

permalink

comment on hair loss: the version I wish someone had shown me in week 1 in c/sideeffects · -16 points · 2 months ago

What is intake actually looking like — fibre and water especially?

permalink

comment on tried Ozempic for 21 weeks. here is what happened. in c/semaglutide · 2 points · 2 months ago

the scale is the least sensitive instrument you own

permalink

comment on someone explain import to me like I have not read a paper in years in c/customs · 8 points · 2 months ago

Push back: personal import allowances are narrow and specific, and the general version of them circulating here is wrong.

permalink

comment on API source — 17 things I got wrong before I got it right in c/compounding · 185 points · 2 months ago

Not convinced. You are comparing a compounded concentration with a branded one and assuming they match.

permalink

comment on how much of what we believe about Apotheke actually comes from pharmacy threads in c/glp1eu · 10 points · 2 months ago

Small fix — those two prices are for different pack sizes, which accounts for most of the gap.

permalink

comment on [Discussion] we are measuring appetite at the wrong time and calling it noise in c/glp1science · 3 points · 2 months ago

glucagon agonism sounds paradoxical until you read the energy expenditure work

permalink

comment on [Question] seizure — what am I missing here in c/customs · 2 points · 2 months ago

clearance time is not carrier time

permalink

comment on [Question] seizure — what am I missing here in c/customs · 55 points · 2 months ago

Import rules are national and they distinguish between personal and commercial import, with different thresholds, documentation and consequences. A general answer is almost always wrong somewhere.

permalink

comment on [Discussion] TRIUMPH is doing more work than we give it credit for in c/trialwatch · 18 points · 2 months ago

The discontinuation numbers were the most useful thing in the paper for me and they were in a supplementary table.

permalink

comment on [PSA] certificate of analysis is not what most of this community thinks it is in c/coa · 12 points · 2 months ago

Right, and net peptide content is where the counterion and the water go. Both numbers can be honest and very different.

permalink

comment on my ApoB moved and I cannot work out whether constipation is why in c/sideeffects · 29 points · 2 months ago

That symptom is not the one being described upthread. Two different things with similar names and the answers are not interchangeable.
