comment on [Meta] proposal — a flair for bacteriostatic water posts in c/reconstitution · 192 points · 1 year ago
the concentration on the vial in marker is the most important step
comment on [Discussion] we are measuring integration at the wrong time and calling it noise in c/hplc · 7 points · 1 year ago
the detector wavelength matters more than people think
comment on [PSA] bacteriostatic water is not what most of this community thinks it is in c/reconstitution · 690 points · 1 year ago
Every time this gets posted it hits the front page and every time someone has to re-explain it.
comment on why does nobody talk about goal weight in c/maintenancephase · 44 points · 1 year ago
the plateau is where the learning happens
comment on reading chargeback threads from 2024 and half of it aged badly in c/cryptopay · 10 points · 1 year ago
escrow for group buys is standard, use it
comment on [Discussion] chromatogram is doing more work than we give it credit for in c/hplc · 382 points · 1 year ago
A shoulder on the main peak that 14 analysts integrated 40 different ways. Same trace, 98.3 spread.

Adding to this: gradient is doing more work than the comment implies.

Gradient goblin mode: changed the solvent composition 14 times, finally got good resolution on a gradient peak.
comment on [Discussion] we are measuring area percent at the wrong time and calling it noise in c/coa · 185 points · 1 year ago
Titration speed is a side-effect dial far more than an efficacy dial.
comment on the confirmations question that gets asked weekly, answered properly in c/cryptopay · 61 points · 1 year ago
gas versus discount arithmetic is real

Sent orfo payment to the wrong chain. Germany, wrong network, vendor could not credit it. 4 day lesson.
comment on switched from 10mg to 7.5mg and the fatigue got better, not worse in c/hplc · 12 points · 1 year ago
integration decision on a shoulder changes your number by half a point on its own
comment on the Netherlands: mg/mL, and what it actually costs here in c/reconstitution · 393 points · 1 year ago
Cosigning. The concentration on the vial in marker is load-bearing.
comment on [Question] concentration — what am I missing here in c/reconstitution · 41 points · 1 year ago
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
comment on stalled for 10 weeks at 5mg and I refuse to panic this time in c/hplc · 225 points · 1 year ago
axis labels included, always
comment on certificate of analysis: the version I wish someone had shown me in week 1 in c/coa · 131 points · 1 year ago
The confident tone is doing a lot of work that the evidence is not.
comment on [Results] 86 weeks on 5mg, full numbers, ask me anything boring in c/reconstitution · 615 points · 1 year ago
show your working or it is unhelpful
comment on [Discussion] LC-MS is doing more work than we give it credit for in c/hplc · 14 points · 1 year ago
The related substances profile is way more interesting than the main peak %. A 98% with 14 peaks is different from a 98% that is one 24% impurity.

I am going to push back on this slightly.
Yes, exactly this, and it is the bit that took me 32 weeks to accept.

never post a calculation as advice without stating the concentration
