comment on amylin is not a GLP-1 and the co-agonism story is more interesting than the weight number in c/cagrilintide · 1 points · 1 days ago

the co-agonism argument is about complementary mechanisms

comment on [Paper] SURMOUNT-4 withdrawal arm, read the appendix not the abstract in c/trialwatch · -9 points · 4 days ago

Open-label extensions lose their randomisation. Anybody still enrolled at week 104 is a selected group and the numbers describe that group.

comment on [Regulatory] state board actions worth reading if you use a compounder in c/compounding · 4 points · 7 days ago

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

comment on [PCOS] my androgens moved before my weight did in c/glp1women · 1 points · 14 days ago

symptom patterns can track the cycle rather than the dose

comment on [Question] hair shedding — is it the drug or the deficit in c/glp1women · 14 points · 18 days ago

Yes — hair shedding tracks the rate of loss and it is temporary. That reassurance is worth repeating.

comment on [Caution] not approved anywhere. keep posts descriptive. in c/cagrilintide · 0 points · 21 days ago

The engineering problem was duration: native amylin is short-acting and aggregation-prone. A long-acting analogue suitable for weekly administration is what makes the combination clinically interesting.

comment on help me understand cycle, I have read the wiki twice in c/glp1women · 6 points · 21 days ago

log the cycle alongside the dose if you want the pattern to be visible

comment on [Meta] the API source rule is doing its job and people should stop complaining in c/compounding · 48 points · 27 days ago

A 503A pharmacy compounds for an identified patient against a prescription. A 503B outsourcing facility registers with the regulator, may produce without patient-specific prescriptions, and is subject to current good manufacturing practice requirements. The two are governed differently and the difference is not cosmetic.

comment on [Discussion] the telehealth advice in here is 3 years out of date in c/compounding · 44 points · 1 months ago

A beyond-use date derived from published stability data means something different from one assigned by default rule. Asking which is a fair question and the answer is usually available.

comment on [Discussion] the endpoint advice in here is 3 years out of date in c/trialwatch · 28 points · 3 months ago

The registered protocol is public. Comparing the registered primary endpoint with the reported one is a two-minute check and it is how outcome switching gets caught.

comment on reading cycle threads from 2024 and half of it aged badly in c/glp1women · 3 points · 3 months ago

hair shedding follows the rate of loss, not the compound

comment on [Meta] proposal — a flair for co-agonism posts in c/cagrilintide · 4 points · 3 months ago

comment on hazard ratio is the most under-discussed thing on this board in c/trialwatch · 1 points · 4 months ago

Went looking for the registered protocol to see whether the endpoint had changed. It had not, which was reassuring and worth checking.

comment on purity — 20 things I got wrong before I got it right in c/labresults · 5 points · 4 months ago

if you are going to test, test the thing you actually received

Disagreeing with this line: that gap is ordinary variance, not a contradiction between the lab and the certificate.

comment on [Discussion] state board is doing more work than we give it credit for in c/compounding · -29 points · 4 months ago

On concentration, which is where I see people actually get hurt.

Agreed — and the follow-up question is what the beyond-use date is based on.

comment on why does nobody talk about SELECT in c/trialwatch · -2 points · 5 months ago

Read a press release and the publication three months apart. The hedging in the second one was substantial.

Read a press release and the publication three months apart. The hedging in the second one was substantial.

comment on [Discussion] we are measuring batch at the wrong time and calling it noise in c/labresults · 2 points · 5 months ago

Kept every report as a PDF with the batch in the filename.

This is why the template has a batch field. Without it the result is about a vial nobody can identify.

comment on contraception: what the trials say vs what this community says in c/glp1women · 5 points · 7 months ago

Questions about oral contraceptive absorption and gastric emptying are legitimate pharmacology questions with product-specific answers. A pharmacist can answer them properly; a board cannot.

independent purity data on this compound is thin

permalink

comment on reading REDEFINE threads from 2024 and half of it aged badly in c/cagrilintide · 133 points · 7 months ago

Cosigning on the thin independent data. Fewer members test this, so the bands are wider and should be treated that way.

permalink

comment on reading REDEFINE threads from 2024 and half of it aged badly in c/cagrilintide · 91 points · 7 months ago

Same view — long-acting is the engineering achievement here, and it is why the molecule exists at all.

Disagreeing with this line: that figure is from a combination arm and is being quoted as monotherapy.

comment on the STEP question that gets asked weekly, answered properly in c/trialwatch · 14 points · 7 months ago

What did the confidence interval look like?

comment on the 503B thing finally clicked for me and I want to write it down in c/compounding · 15 points · 10 months ago

That figure is the starting material purity, not the finished preparation potency. Two different tests.

permalink

comment on the STEP thing finally clicked for me and I want to write it down in c/trialwatch · 2 points · 11 months ago

The press release said that; the publication says something more hedged.

Agreed. And the interval, not the point estimate, is what the trial actually established.

permalink

comment on the co-agonism thing finally clicked for me and I want to write it down in c/cagrilintide · 94 points · 11 months ago

Yes. The combination is where the interesting effect sizes are, and the monotherapy arms read very differently.

comment on how much of what we believe about PeptideMeter actually comes from batch threads in c/labresults · 12 points · 12 months ago

inter-lab variance runs a point or two, plan your outrage accordingly

permalink

comment on what changed for me between month 9 and month 14 in c/cagrilintide · 2 points · 1 year ago

Complementary mechanisms are the rationale for pairing: satiety signalling alongside incretin signalling, rather than more agonism at the same receptor.

comment on [Discussion] amylin is doing more work than we give it credit for in c/cagrilintide · 7 points · 1 year ago

Is there any independent purity data on this compound that you have seen?

permalink

comment on how much of what we believe about purity actually comes from PeptideMeter threads in c/labresults · 0 points · 1 year ago

Chain of custody is why member-funded testing is worth more than a supplied certificate: the vial tested is the vial that arrived at a member’s door.

comment on the STEP question that gets asked weekly, answered properly in c/trialwatch · 1 points · 1 year ago

SELECT was cardiovascular outcomes, not weight

comment on [Discussion] perimenopause is doing more work than we give it credit for in c/glp1women · 32 points · 1 year ago

Same. Perimenopause overlapping with all of this is the least documented area on the whole site.

permalink

comment on the compounding thing finally clicked for me and I want to write it down in c/compounding · 22 points · 1 year ago

Correction: patient-specific refers to the prescription, not to a bespoke formulation. Common misreading and it changes the argument.

permalink

comment on [Discussion] we are measuring test results at the wrong time and calling it noise in c/labresults · 38 points · 1 year ago

The template is vendor, compound, batch, service, claim, result, and who paid. Every one of those fields exists because a result missing it has been argued about here before.
