comment on [Lab] CPC cagri — Janoshik came back 98.4% against a claimed 97.5% in c/cagrilintide · 29 points · 6 months ago

Agreed — it is an amylin analogue and importing intuitions from the incretin boards produces confident nonsense.

comment on [Question] co-agonism — what am I missing here in c/cagrilintide · 5 points · 7 months ago

Sent a vial to VendorInvestigate because there was almost nothing on file for this compound. 98.5% against a claimed 98.0%, and I posted it because the log needs entries.

comment on Ireland: Canada, and what it actually costs here in c/glp1canada · 37 points · 8 months ago

Quantity limits restrict how much may be dispensed in a period even where coverage exists. They are a distinct barrier and require a distinct request.

comment on 14 months in and retatrutide is still the thing I get wrong in c/retatrutide · 1 points · 8 months ago

The phase 2 readout ran to 48 weeks in a few hundred participants with a slow escalation. Both the size and the duration matter when people quote the headline number.

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

Agreed that the endpoint definitions matter enormously and almost nobody reads them before quoting a response rate.

comment on small win: Mounjaro stopped being a problem at week 66 in c/tirzepatide · 49 points · 10 months ago

Right. And the sema-to-tirz "conversion" people post is invented. There is no published equivalence.

comment on unpopular opinion: most of what gets said here about TRIUMPH is guesswork in c/retatrutide · 0 points · 10 months ago

not approved anywhere, which is the single most important fact in this board

marta_vanhecke is right about the escalation being the variable. It explains most of the difficult reports here.

comment on the GIP question that gets asked weekly, answered properly in c/tirzepatide · 395 points · 11 months ago

On comparing yourself with the trial number.

SURMOUNT-1 reported roughly 21% mean body weight change at 72 weeks on the highest arm. Three things get dropped every time that figure is quoted here. It is a mean, and the distribution around it is very wide. It is 72 weeks, which is a year and a half. And it is a trial population with trial support, which is not the same as a person with a spreadsheet.

Use it as a rough shape, not a benchmark. A 12% year is inside the ordinary range and people quit over it every week on this board.

comment on [PSA] special authorization is not what most of this community thinks it is in c/glp1canada · 13 points · 11 months ago

Formulary criteria are revised, and plan renewal is a natural point at which a previously refused request may succeed without anything about the applicant changing.

comment on [Question] how do you actually verify glucagon in c/retatrutide · 1 points · 11 months ago

Agreed on the heart-rate reports. They are consistent enough across the threads to be worth noting, not enough to be a finding.

comment on [Question] lowest effective dose — what am I missing here in c/maintenancephase · 4 points · 1 year ago

appetite returns before the scale acknowledges anything

comment on someone explain dual agonist to me like I have not read a paper in years in c/tirzepatide · 1 points · 1 year ago

The 21% figure is a 72-week mean on the highest arm. Quoting it as what someone should expect by week 49 is not a fair reading.

comment on someone explain HPLC to me like I have not read a paper in years in c/hplc · 92 points · 1 year ago

Correction: that is a tailing factor, not a plate count. Different diagnostics for different problems.

permalink

comment on does method development actually matter or is it forum lore at this point in c/hplc · 11 points · 1 year ago

Disagreeing with this bit: that spread is ordinary inter-lab variance, not a disagreement about the material.

This is the whole methodological point of the board in one line.

comment on [Question] how do you actually verify Zepbound in c/tirzepatide · 74 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 small win: goal weight stopped being a problem at week 85 in c/maintenancephase · 170 points · 1 year ago

On stopping, since it is the question underneath most posts here.

Withdrawal studies in this class show substantial regain after discontinuation, consistently, across compounds. Appetite returns first, typically well before the scale moves. That is a statement about the pharmacology of a chronic condition, not about anybody’s character, and the framing matters because people quit in shame over an entirely predictable result.

If you are going to stop — for cost, for supply, for any reason — the useful preparation is deciding in advance what you will watch for and what your plan is when appetite comes back. Doing that in advance is much easier than doing it in a panic, and it is a conversation to have with someone who knows your history.

comment on tried triple agonist for 19 weeks. here is what happened. in c/retatrutide · 50 points · 1 year ago

It is a triple agonist at the GLP-1, GIP and glucagon receptors. The glucagon arm is the genuinely novel component and it is the one with the least human outcome data behind it.

permalink

comment on [Results] 2 weeks on 7.5mg, full numbers, ask me anything boring in c/cagrilintide · 21 points · 1 year ago

Dosing intuitions from the GLP-1 boards do not transfer. Different receptor family, different exposure-response, and no published schedule for members to reason from.

comment on help me understand SURMOUNT, I have read the wiki twice in c/tirzepatide · 63 points · 1 year ago

Careful with "everyone tolerates it better". The people it did not suit stop posting, which makes this board look calmer than the drug is.

permalink

comment on the province thing finally clicked for me and I want to write it down in c/glp1canada · 10 points · 1 year ago

Quantity limits restrict how much may be dispensed in a period even where coverage exists. They are a distinct barrier and require a distinct request.

comment on dose escalation — my 16-week log, condensed into one table in c/retatrutide · 112 points · 1 year ago

What do you think the glucagon component is adding, specifically?

permalink

comment on 4 months in and hepatic fat is still the thing I get wrong in c/survodutide · 7 points · 1 year ago

Not convinced. Imaging-based fat fraction is not the same as a histological response and the paper is explicit about that.

permalink

comment on 4 months in and hepatic fat is still the thing I get wrong in c/survodutide · 11 points · 1 year ago

That is an escalation schedule for an unapproved compound and this board does not host those.

comment on stalled for 12 weeks at 10mg and I refuse to panic this time in c/retatrutide · 1 points · 1 year ago

the glucagon component is why the metabolic story reads differently

comment on triple agonist: the version I wish someone had shown me in week 1 in c/retatrutide · 1 points · 1 year ago

What is the source for that figure — the published paper or a summary of it?

permalink

comment on [Lab] WXT reta — PeptideMeter came back 97.7% against a claimed 97.0% in c/retatrutide · 14 points · 1 year ago

Sceptical of the extrapolation. Forty-eight weeks does not tell you about seventy-two, and the curve shape is exactly what is unknown.

comment on [Discussion] chromatogram is doing more work than we give it credit for in c/hplc · 75 points · 1 year ago

UV response is not uniform across species. At 214nm you are looking at the peptide bond, which is why it is the working wavelength for this class; at 280nm you only see tryptophan, tyrosine and phenylalanine.

What is the waist doing? That is usually the number still moving during a scale stall.

permalink

comment on [PSA] GIP is not what most of this community thinks it is in c/tirzepatide · 8 points · 1 year ago

the appetite effect is blunter than sema, in a good way, most weeks

Not sure about this bit. The GIP arm being real does not tell you that it is what caused your particular week.
