Carryover from a previous high-concentration injection looks exactly like a small impurity. The blank injection is four minutes and it removes the ambiguity entirely.

Agreed, and the trial number is a mean of a very wide distribution — the tails are enormous and nobody posts from the middle.

Minor fix — the half-life is about a week, not about a day. The rest of your point stands.

Correcting myself from earlier in the thread: I said week 6 and it was week 10. Same shape, wrong number.

Sat at 1.7mg for four months because it was doing the job. Everyone told me to go up. The one time I did, the only thing that changed was the injection-site soreness.

area percent is relative to what the detector saw and nothing else

That is area percent, not mass percent. The trace cannot give you the second one.

you cannot report to two decimals off that baseline

research-use-only material is not approved for human use, full stop

It is a triple agonist at the GLP-1, GIP and glucagon receptors.

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

2.4 is a ceiling, not a target

area percent is relative to what the detector saw and nothing else

Sent a vial to PeptideMeter out of curiosity. Result was 97.6% against a claimed 97.5%, which is the first independent number I had seen for this compound anywhere.

the column has a history and it shows in the peak shape

the scale is the least sensitive instrument you own

On being wrong in public, which is the best thing that happens here.

Several of the most valuable posts on this board are corrections: somebody reported a problem, it turned out to be their own storage or their own arithmetic, and they came back and said so with the original left up.

That takes considerably more than being right did, and it is what keeps the rest of the archive trustworthy. A board of unretracted accusations is worthless within a year. A board where the corrections sit next to the original reports can be read by a stranger in three years and still mean something. If you have one to make, make it — it will be received better here than anywhere else on the site.

if 7.5 is working, 10 is not automatically better

Right, and it bears repeating that nothing here is approved anywhere and research material is not for human use.

Retention time shifted 0.4 minutes and I assumed the worst. It was the column temperature.

Careful. A four-week stall is inside normal variation and treating it as failure is how people escalate for no reason.

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

Steady state after a dose change takes four to five half-lives, so the fair judgement point on a new step is about a month, not four days.

Week 80 was the first time the scale moved after a five-week stall. I changed nothing in that window.

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

Which week did the appetite change actually land for you?

Saving this one. It is the clearest statement of the stall problem I have read here.

switching from sema is not a dose conversion, there is no clean equivalence

Disagree with this specific line.

Adding one thing to this: the appetite effect and the scale run on separate clocks, so both halves can be true at once.

small trial, big effect, wide error bars

Careful. A four-week stall is inside normal variation and treating it as failure is how people escalate for no reason.

This. The phase 2 result was genuinely large and it was also 48 weeks in a few hundred people.

Nothing containing this compound is approved anywhere.

Disagree with this specific inference. A 48-week readout does not tell you the shape of the curve after it.

Week 94 was the first time the scale moved after a five-week stall. I changed nothing in that window.

Careful — you are treating retention time as identity. Two things can co-elute and the trace will not tell you.

System suitability — repeat injections, tailing factor, plate count, RSD on area — is what tells you the instrument was fit for the measurement that day. Without it, the purity figure is unanchored.

Week 59: 25kg down, constipation basically gone since about week 9, and the honest headline is that nothing dramatic happened. It was boring and it worked.

Kept a log from week one and the single most useful column turned out to be waist, not weight.

Does reflux track the day after the shot, or is it there all week?
