comment on does beginner actually matter or is it forum lore at this point in c/newbiequestions · 2 points · 1 year ago

week two with nothing happening is normal

comment on the STEP question that gets asked weekly, answered properly in c/trialwatch · 25 points · 1 year ago

Small fix — that was the cardiovascular outcomes trial, so weight was a secondary endpoint and the population was different.

a mean is not a promise

This is the distinction that would end about half the arguments on this board.

comment on stalled for 6 weeks at 15mg and I refuse to panic this time in c/sideeffects · 1 points · 1 year ago

Pushback: you changed the dose, the meal timing and the training in the same fortnight, so the attribution is guesswork.

Which day of the week relative to the shot does it hit?

comment on 13 months in and basics are still the thing I get wrong in c/newbiequestions · 21 points · 1 year ago

search first, but a repeat question is not a crime

Concentration is mass over volume, and a U-100 syringe reads 100 units per millilitre. Those two facts are the whole of the arithmetic this board keeps explaining.

comment on [Discussion] the ACHIEVE advice in here is 3 years out of date in c/orforglipron · 1 points · 1 year ago

phase 3 is where the comparison becomes fair

This is the fact the whole board hangs on. Small molecule, not peptide.

Small fix — the two programme names got swapped upthread and it changes which population the figure came from.

jonas_cardoso is right that milligram comparisons across classes tell you nothing.

comment on [PSA] T2D is not what most of this community thinks it is in c/t2dglp1 · 23 points · 1 year ago

variability matters as much as the mean

comment on how much of what we believe about ACHIEVE actually comes from ATTAIN threads in c/orforglipron · 0 points · 1 year ago

Milligram-for-milligram comparison with an injectable peptide is not meaningful and I should not have made it.

comment on my TSH moved and I cannot work out whether ACHIEVE is why in c/orforglipron · 23 points · 1 year ago

Which programme and which readout are you quoting?

permalink

comment on [Results] 36 weeks, 9kg, and oral GLP-1 was the hard part in c/orforglipron · 21 points · 1 year ago

Is that from the publication or the press release?

comment on bacteriostatic water is the most under-discussed thing on this board in c/reconstitution · 347 points · 1 year ago

Agreed on the swirl. There is no reason to shake it and a good reason not to.

comment on gallbladder — 15 things I got wrong before I got it right in c/sideeffects · 1.4k points · 1 year ago

Most of the common complaints trace back to slowed gastric emptying — early fullness, reflux, nausea after a large or fatty meal. That is also why meal size and speed change the experience more than anything else.

comment on unpopular opinion: most of what gets said here about discontinuation is guesswork in c/tapering · 132 points · 1 year ago

Is this a pause or a stop? They are different plans.

permalink

comment on is it normal to get constipation at week 11 in c/newbiequestions · 4 points · 1 year ago

Bacteriostatic water contains a preservative, which is what makes repeated entry into a vial reasonable. Sterile water does not, and the two are not interchangeable for that purpose.

comment on reading oral GLP-1 threads from 2024 and half of it aged badly in c/orforglipron · 10 points · 1 year ago

oral semaglutide is a peptide with an absorption enhancer, this is not that

permalink

comment on [Discussion] can we stop arguing about fatigue until somebody posts a number in c/sideeffects · 1 points · 2 years ago

reflux on day two and gone by day four is the standard shape

permalink

comment on 5 months in and metformin is still the thing I get wrong in c/t2dglp1 · 1 points · 2 years ago

Time in range told me far more than the average did. Two quarters with the same A1c looked completely different on the sensor.

permalink

comment on [Question] heart rate — what am I missing here in c/sideeffects · 1 points · 2 years ago

The fatigue turned out to be that I was eating about a third of what I thought I was. Tracked it for a week and the mystery evaporated.

permalink

comment on what changed for me between month 4 and month 12 in c/newbiequestions · 31 points · 2 years ago

I would not panic about that. It is on the list of ordinary first-month experiences.

comment on [Discussion] the mg/mL advice in here is 3 years out of date in c/reconstitution · 30 points · 2 years ago

What is written on the vial right now?

permalink

comment on [PSA] write the concentration on the vial. that is the whole post. in c/trialwatch · 64 points · 2 years ago

Relative risk reduction without the baseline rate is uninterpretable. A large relative reduction on a small absolute risk is a small absolute benefit.

permalink

comment on [PSA] constipation is not what most of this community thinks it is in c/sideeffects · 2 points · 2 years ago

Right, and the hair thing is worth repeating: it tracks the rate of loss rather than the compound, and it stops.

permalink

comment on [PSA] mg/mL is not what most of this community thinks it is in c/reconstitution · 823 points · 2 years ago

Careful — that arithmetic is wrong. 10mg in 3mL is 3.33mg/mL, so 1.5mg draws to 45 units, not what you wrote.

permalink

comment on someone explain nausea to me like I have not read a paper in years in c/sideeffects · 32 points · 2 years ago

Same pattern here. It settled at a stable dose without me doing anything clever.

comment on bacteriostatic water — 16 things I got wrong before I got it right in c/reconstitution · 1 points · 2 years ago

Asked GGPeps what volume they reconstitute to for their own stability testing and they answered in one line. Useful thing to know.

Adding more water does not change how much peptide is in the vial.

This is the sentence that makes the rest unnecessary. Write it on the vial and the problem is gone.
