A cold box is thermal mass plus insulation. Most kits get the insulation part wrong.

comment on nausea day 2 post-injection like clockwork, week 14, does it ever stop in c/sideeffects · 62 points · 1 days ago

Severe, or unpleasant? They are genuinely different questions and the answers diverge.

smaller meals, earlier, is the boring advice that works

Disagreeing with this one line: that symptom is not on the wait-and-see list and should not be posted as though it is.

comment on [Failure] gel pack arrived liquid and warm in July. photos at unboxing. in c/coldchain · 176 points · 3 days ago

The specific failure here is almost certainly thermal mass rather than insulation. A single small pack in a large void has nothing to hold the temperature with; the pack exhausts and then the air in the box does whatever the outside is doing.

Two smaller packs plus a snugger void outperforms one bigger pack in a loose box, and it costs the same.

comment on [Paper] survodutide MASH data is the most interesting hepatic readout in the class in c/survodutide · 43 points · 3 days ago

It is a dual agonist at the GLP-1 and glucagon receptors. The glucagon arm is associated with increased energy expenditure and with effects on hepatic fat, which is why the development programme is oriented towards liver disease.

the other thing a logger shows you is your own fridge. i put one in mine for a week expecting to be smug and found 2.1°C at the back and 7.8°C in the door.

That reads as a recommendation and the source pages deliberately are not. They are a record you use to make your own decision.

That figure is from the obesity programme, and this thread is about the hepatic one.

Yes — nothing containing this is approved anywhere, which is the first fact and usually the last one mentioned.

comment on A1c 9.1 → 5.4 over 14 months, full table inside in c/bloodwork · 0 points · 9 days ago

Substantial weight loss independently moves lipids, liver enzymes and several other markers. Attributing a change to a compound while losing weight is confounded by design.

comment on how many independent tests before you trust a vendor. my number is three in c/vendorvetting · 73 points · 10 days ago

I would separate documentation from logistics. A supplier can be excellent at one and ordinary at the other, and averaging them hides it.

Small fix — a reference interval is not a treatment target, and the post above uses them interchangeably.

MASH endpoints are histological, which is a much harder bar

Yes. Holding the dose is a real option and it does not mean you have failed at anything.

Six orders across two years from HJ. Same packaging, same paperwork, same lead time. The most boring supplier relationship I have and I mean that as praise.

Not convinced by the attribution. Weight loss alone moves that marker and you have no way to separate the two.

How to make a panel worth comparing, which is most of the value people leave on the table.

Standardise the conditions: same lab, same fasting state, same rough time of day, same point in the week, similar hydration. Take a baseline before you change anything. Repeat any surprising value before acting on it. Change one thing at a time if you want to attribute anything to it.

Do that and a year of panels is a trend. Skip it and a year of panels is a collection of unrelated mornings, which is what most of the alarmed posts here are actually describing.

comment on the MASH thing finally clicked for me and I want to write it down in c/survodutide · 104 points · 4 months ago

read the histology endpoint definitions before quoting a response rate

permalink

comment on [Question] how do you actually verify MASH in c/survodutide · 187 points · 4 months ago

What this compound is actually being developed for, since the boards treat it as a weight-loss molecule with a footnote.

It is a dual GLP-1 and glucagon receptor agonist, and the glucagon arm links to hepatic fat and energy expenditure. The headline programme is metabolic liver disease, with endpoints scored on biopsy rather than on a scale.

That matters for how the data should be read. A histological response rate in a biopsy-confirmed population answers a very different question from a mean weight change in an obesity trial, and quoting one in place of the other — which happens in nearly every thread here — is not a comparison.

Disagree. Severe abdominal pain is not on the list of things to wait out, and this board should not be treating it as one.

That is a non-fasting value and the interval you are comparing it against is a fasting one.

comment on is it normal to get reflux at week 5 in c/sideeffects · 64 points · 5 months ago

Small fix — the shedding follows the rate of weight loss, not the compound, and it is temporary.

permalink

comment on why does nobody talk about baseline labs in c/bloodwork · 71 points · 6 months ago

The confounding problem, stated plainly, because this board keeps stepping on it.

Substantial weight loss moves lipids, liver enzymes, insulin sensitivity markers and several others in its own right. If you are losing weight while taking something, any change in those markers has at least two candidate explanations and you cannot separate them from your own panel.

What you can do is standardise, take a baseline, keep the series long, and be honest in your posts about what is and is not attributable. The threads that say "this compound did X to my ApoB" almost never have the design to support the claim, mine included.
