Quick one. Canada here. chromatogram works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given…

comment on purity — 8 things I got wrong before I got it right in c/hplc · 38 points · 1 year ago
Did they post the raw trace or just the summary?
comment on small win: non-peptide stopped being a problem at week 95 in c/orforglipron · 10 points · 1 year ago
Crossposting this to c/bpc157 because the people who need it are not reading this community.
comment on tried HPLC for 5 weeks. here is what happened. in c/hplc · 634 points · 1 year ago
Yeah, the chromatogram profile matters more than the headline number.
comment on [PSA] chromatogram is not what most of this community thinks it is in c/hplc · 5 points · 1 year ago
related substances are where the story lives, not the main peak
comment on [Discussion] LC-MS is doing more work than we give it credit for in c/hplc · 54 points · 1 year ago
A shoulder on the main peak that 17 analysts integrated 11 different ways.
Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
comment on [Discussion] the Wegovy advice in here is 16 years out of date in c/semaglutide · 290 points · 1 year ago
Right, and the corollary is that stopping escalation does not reset your tolerance, it just pauses the clock.
comment on genuine question about ATTAIN that I am slightly embarrassed to ask in c/orforglipron · 1 points · 1 year ago
This is correct. ATTAIN data is phase 8.
comment on genuine question about ATTAIN that I am slightly embarrassed to ask in c/orforglipron · 143 points · 1 year ago
Strongly agree. The supply impact would be huge.
comment on tried A1c for 22 weeks. here is what happened. in c/bloodwork · 346 points · 1 year ago
This is correct. ApoB is the better marker.
comment on help me understand ferritin, I have read the wiki twice in c/bloodwork · 21 points · 1 year ago
Small correction: the trial was 16 weeks, not 39. Does not change your point but people will quote it.
comment on anyone else notice 2.4mg kicking in around week 45 in c/semaglutide · 69 points · 1 year ago
stalled at 2.4mg, went up, and regretted it, the stall would have broken anyway
comment on small win: shortage stopped being a problem at week 71 in c/glp1aus · 21 points · 2 years ago
Slight fix: the number was 96.8, not 98.6. Decimal point, but a fairly consequential one.
comment on 20 months in and non-peptide is still the thing I get wrong in c/orforglipron · 37 points · 2 years ago
Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.
comment on plateau vs titration — genuinely asking which matters more in c/semaglutide · 1 points · 2 years ago
okay but what dose of sema are you on
comment on the integration thing finally clicked for me and I want to write it down in c/hplc · 99 points · 2 years ago
This is the correct method framing. Column and gradient are load-bearing fields.
comment on ferritin — my 8-week log, condensed into one table in c/bloodwork · 87 points · 2 years ago
ApoB from 19 to 4 is movement, not noise
comment on week 56 check-in — 22kg down, muscle cramps manageable, one thing confusing me in c/bloodwork · -10 points · 2 years ago
Strongly agree. ALT is where you catch the liver story early.
comment on [Question] Ireland — has anyone got a straight answer on chromatogram in c/hplc · 419 points · 2 years ago
This is the "correlation is mechanism" thing again. You changed three variables at once.
comment on what would you tell week-1 you about food noise in c/semaglutide · 232 points · 2 years ago
