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 [Discussion] restarting is not failing and we should say that louder in c/tapering · 2 points · 13 days ago
have the conversation with a clinician before, not after
comment on [Paper] amylin co-agonism is genuinely different pharmacology, not just more GLP-1 in c/glp1science · -28 points · 15 days ago
gastric emptying slows, it does not stop
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.
comment on [Explainer] which labs are worth repeating quarterly and which are theatre in c/bloodwork · 11 points · 22 days ago
Do you have a baseline from before you started?
comment on [Struggle] eight weeks, 2kg, doing everything right, and it is grinding me down in c/progresspics · 55 points · 24 days ago
the middle is the part nobody posts and everybody lives in
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] we are measuring A1c at the wrong time and calling it noise in c/bloodwork · 17 points · 1 months ago
a single triglycerides outside range is a reason to repeat, not to panic
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.
comment on how much of what we believe about area percent actually comes from COA threads in c/coa · 69 points · 1 months ago
area% is not mass%, and the difference is the whole game
comment on genuine question about area percent that I am slightly embarrassed to ask in c/coa · 33 points · 2 months ago
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 · -20 points · 2 months ago
identity and quantity are two questions and most documents answer one
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.
comment on how much of what we believe about regain actually comes from discontinuation threads in c/tapering · 2 points · 2 months ago
Went back on after eight months away. Nobody here made me feel bad about it, which mattered more than I expected.
comment on TRIUMPH is the most under-discussed thing on this board in c/retatrutide · 9 points · 2 months ago
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.
comment on [Non-Scale Win] my knees stopped hurting and i cried about it in c/progresspics · 3 points · 2 months ago
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 [Non-Scale Win] my knees stopped hurting and i cried about it in c/progresspics · 5 points · 2 months ago
waist is the measurement that keeps moving during a scale stall
comment on [Discussion] we are measuring appetite at the wrong time and calling it noise in c/glp1science · 12 points · 2 months ago
mechanism explains a direction, not a magnitude
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 [Results] 9 weeks on 7.5mg, full numbers, ask me anything boring in c/tapering · 67 points · 2 months ago
coming back later is allowed and it is common
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.
comment on [Meta] proposal — a flair for Medutest posts in c/labresults · 4 points · 3 months ago
Kept every report as a PDF with the batch in the filename. Two years in, it is the most useful folder I own.
comment on [Meta] proposal — a flair for Medutest posts in c/labresults · 9 points · 3 months ago
Which service, and did you pay for it yourself?
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.
comment on someone explain retatrutide to me like I have not read a paper in years in c/retatrutide · 372 points · 3 months ago
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.
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 [Meta] proposal — a flair for phase 2 posts in c/retatrutide · 129 points · 3 months ago
small trial, big effect, wide error bars
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.
comment on [PSA] purity is not what most of this community thinks it is in c/coa · 195 points · 4 months ago
post the whole document, not the headline number
comment on [Results] 49 weeks, 7kg, and dose escalation was the hard part in c/retatrutide · 112 points · 4 months ago
the phase 2 numbers were striking and they were also 48 weeks in a small population
comment on the test results thing finally clicked for me and I want to write it down in c/labresults · 1 points · 5 months ago
results without method are gossip with decimals
comment on area percent — 13 things I got wrong before I got it right in c/coa · 77 points · 5 months ago
axis labels included, always
comment on [Results] 88 weeks on 2.4mg, full numbers, ask me anything boring in c/retatrutide · 305 points · 5 months ago
Agreed, and the framing that helps is: this is a phase 2 compound with phase 3 running. Everything else is inference.
