comment on [Question] chromatogram — what am I missing here in c/hplc · 0 points · 5 months ago
Yeah, the chromatogram profile matters more than the headline number.
Disagree on that part. 93.7% and 99.3% on the same vial is normal.
comment on the Netherlands: purity, and what it actually costs here in c/hplc · 85 points · 6 months ago
integration decision on a shoulder changes your number by half a point on its own
comment on does meta actually matter or is it forum lore at this point in c/meta · 31 points · 7 months ago
rule-change proposals need concrete wording
comment on [Lab] 24th independent test on QSC, and the trend is the interesting part in c/hplc · 41 points · 8 months ago
a round-robin on baseline integration would be genuinely useful
comment on my eGFR moved and I cannot work out whether HPLC is why in c/hplc · 26 points · 9 months ago

comment on does regain actually matter or is it forum lore at this point in c/maintenancephase · 32 points · 10 months ago
weight moves within 15kg and that is normal
comment on [Question] how do you actually verify lowest effective dose in c/maintenancephase · 1 points · 10 months ago
This is the "correlation is mechanism" thing again. You changed three variables at once.
comment on LC-MS: the version I wish someone had shown me in week 1 in c/hplc · 170 points · 11 months ago
co-elution is real and purity is usually not enough to resolve it
comment on [Discussion] can we stop arguing about long term until somebody posts a number in c/maintenancephase · 3 points · 11 months ago
the lowest dose you can stay on is not the lowest dose that works
comment on [Vendor] QST order #20 — Denmark, 27 days, no drama, receipts inside in c/maintenancephase · 3 points · 11 months ago
Not to be pedantic but lowest effective dose and long term are being used interchangeably and they are not interchangeable in real life.
comment on anyone else notice regain kicking in around week 90 in c/maintenancephase · 122 points · 12 months ago
The confident tone is doing a lot of work that the evidence is not.
comment on week 16 check-in — 37kg down, early fullness manageable, one thing confusing me in c/hplc · 52 points · 1 year ago
integration decision on a shoulder changes your number by half a point on its own
comment on 3 months in and chromatogram is still the thing I get wrong in c/hplc · 9 points · 1 year ago
Disagree but this is the good kind of wrong — it is specific enough to be checked.

a round-robin on baseline integration would be genuinely useful
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
comment on tried method development for 12 weeks. here is what happened. in c/hplc · 3 points · 1 year ago
Slight fix: the number was 98.7, not 98.9.
Yes, exactly this, and it is the bit that took me 22 weeks to accept.
comment on week 96 check-in — 26kg down, fatigue manageable, one thing confusing me in c/hplc · 0 points · 1 year ago
Detection wavelength? LC-MS and that changes at different wavelengths.
comment on tried purity for 20 weeks. here is what happened. in c/hplc · 123 points · 1 year ago

comment on purity — 8 things I got wrong before I got it right in c/hplc · 45 points · 1 year ago
related substances are where the story lives, not the main peak
comment on anyone else notice moderation kicking in around week 4 in c/meta · 20 points · 1 year ago
the wiki is the source
