Highlights from this day
  • slow.taper — this is the single most misquoted result of the last few years 14:09
  • aliquot_ada — thats the part i keep having to explain to people 14:36
  • peak_split — correct, and thats most trials 18:34

give it four weeks

OW

did anybody find a difference between SGN and pharmacy at the same 2.5

slower worked better

how long till steady state, ive read the half life is about a week

the plateau hit me at 27 weeks and moved again about a month later without a dose change, we shall see

OW

steady state is the bit people skip, judging a new dose after eight days tells you almost nothing

unrelated but £185 a month for compounded against what brand costs locally is why most people here use vials, still working it out

compounded and brand felt the same to me at 2.4, which is one person and nothing more

BW

my 40 vial in 3ml gives 4mg/ml so 0.5 lands on 12 units, thats why i picked that volume

FA

FLOW was the kidney outcomes trial and it gets quoted in here for things it didnt measure

BW

changed my mind on the four week rule, i think it depends entirely on how the current dose feels, happy to be corrected

BW

my PeptideMeter report on the QSC vial came back 99.4 against a certificate saying 97.4

BW

brand vs compounded, is there a difference people can actually feel
my plateau was the scale stopping while appetite stayed suppressed, which is a different problem

AA

SELECT is the one people bring up when they want to argue this is a heart drug now

PS

Cited study
SELECT — semaglutide 2.4 mg and cardiovascular outcomes in overweight or obesity without diabetes
NEJM · 2023
over 17,000 participants, MACE primary endpoint, no diabetes at entry

the headline is a roughly 20% relative reduction in the three point MACE composite

PS

hazard ratio came in around 0.80 with a confidence interval that stayed under 1

PS

relative. absolute difference was a couple of percentage points over several years

both numbers are true and they feel completely different, which is the whole problem with reporting this stuff

ST

this is the single most misquoted result of the last few years

it mattered here for a different reason. it changed what my GP was willing to talk about

before SELECT it was a cosmetic conversation. after, it was a risk conversation

PS

the separation in the event curves started earlier than the weight loss could plausibly explain, which is why people argue for a direct vascular effect

argue is the right word though. its an inference from curve shape, not a proven mechanism

PS

probably both and SELECT was not designed to separate them

ST

worth noting the entry criteria. established cardiovascular disease and BMI 27 or over, no diabetes

if you are 34 with no history you are not in that population and the hazard ratio is not yours

PS

yep, and CRP often moves more than the lipids do. different levers

AA

back. anyway my takeaway is SELECT is good news that doesnt tell me what to do this week
