comment on reta phase 2 was -24.2% at 48 weeks and people quote it like it is a maintenance number in c/retatrutide · 85 points · 2 days 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.

comment on is anyone tracking heart rate properly on reta or are we all guessing in c/retatrutide · 32 points · 5 days ago

Glucagon receptor agonism is associated with increased energy expenditure and with hepatic effects. That is a mechanistic story with strong preclinical support and limited phase 2 human data.

comment on [PeptideMeter] QSC tirz — 97.1%, second sample from the same batch in c/labresults · 1 points · 13 days ago

Disagree that this is a discrepancy. 97.1% against a claimed 97.0% is inside ordinary inter-lab variance in either direction.

comment on [Paper] amylin co-agonism is genuinely different pharmacology, not just more GLP-1 in c/glp1science · -28 points · 15 days ago

comment on the retatrutide question that gets asked weekly, answered properly in c/retatrutide · 1 points · 16 days ago

Disagree. "More receptors means more effect" is not how any of this works and the trial data does not support the linear story.

comment on [Explainer] which labs are worth repeating quarterly and which are theatre in c/bloodwork · 2 points · 21 days ago

Reference intervals are typically the central 95% of a reference population. By construction one person in twenty falls outside one on any given test without anything being wrong.

Do you have a baseline from before you started?

comment on [Explainer] why an oral non-peptide escapes the absorption problem entirely in c/glp1science · 110 points · 25 days ago

GLP-1 receptor agonism acts both peripherally — insulin secretion in a glucose-dependent way, slowed gastric emptying — and centrally, on appetite regulation. The central component is the better explanation for sustained intake reduction.

comment on [Discussion] certificate of analysis is doing more work than we give it credit for in c/coa · 1 points · 1 months ago

area% is not mass%, and the difference is the whole game

Disagree on this specific point. Two honest labs can resolve that impurity differently and report different numbers.

The document I was worried about turned out to be a re-issue with a later creation date. Asked, got the original, entirely ordinary.

comment on genuine question about area percent that I am slightly embarrassed to ask in c/coa · 142 points · 2 months ago

Sent one vial to Medutest and VendorInvestigate. 98.2% and a claimed 97.5%. Cost me more than the vial and I would do it again.

Went back on after eight months away. Nobody here made me feel bad about it, which mattered more than I expected.

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

comment on help me understand COA, I have read the wiki twice in c/coa · 20 points · 2 months ago

Disagree that a lower number is automatically worse. A conservative claim that survives testing is worth more than an optimistic one that does not.

My goal weight at week one was a number I made up. I have revised it twice since and I am happier for it.

comment on am I the only one who found ferritin harder than the injections in c/bloodwork · 0 points · 2 months ago

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

This is the sentence to read before anybody panics about a single value.

comment on [Results] 9 weeks on 7.5mg, full numbers, ask me anything boring in c/tapering · 1 points · 2 months ago

How long were you at the dose you are coming off?

Disagreeing with this bit: stretching and reducing are different things and the post treats them as one.

comment on [PSA] timeframe is not what most of this community thinks it is in c/progresspics · 31 points · 3 months ago

Small correction, kindly meant: that is a range rather than a regain. Weight moves day to day in everybody.

Kept every report as a PDF with the batch in the filename. Two years in, it is the most useful folder I own.

Which service, and did you pay for it yourself?

permalink

comment on [Meta] proposal — a flair for Medutest posts in c/labresults · 0 points · 3 months 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.

comment on the gastric emptying thing finally clicked for me and I want to write it down in c/glp1science · 4 points · 3 months ago

Tolerance to the gastric effect develops with continued exposure while the appetite effect largely persists. That single fact explains most of the "it settles but it still works" pattern the side-effect board reports.

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

comment on someone explain retatrutide to me like I have not read a paper in years in c/retatrutide · 661 points · 3 months ago

Sent a vial to VendorInvestigate out of curiosity. Result was 99.1% against a claimed 99.0%, which is the first independent number I had seen for this compound anywhere.

permalink

comment on someone explain retatrutide to me like I have not read a paper in years in c/retatrutide · 263 points · 3 months ago

Stopped at a low step because there was no reason to go further and no data to tell me what further would do.

comment on reading TRIUMPH threads from 2024 and half of it aged badly in c/retatrutide · 27 points · 4 months ago

Correction: TRIUMPH is the phase 3 programme. The number you are quoting is from the phase 2 readout, which is a different trial.
