What is the PBS status?
comment on [Lane Report] Wuxi → Germany, 8 days, best packaging i have seen in c/intlshipping · 1 points · 11 days ago
packaging quality matters on the 4-hour segments
comment on [Question] what is a reasonable system suitability RSD for this work in c/hplc · 28 points · 17 days ago
Not to be pedantic but gradient and chromatogram are being used interchangeably and they are not interchangeable in real life.
comment on [Question] does anyone have a straight answer on transit vs destination liability in c/customs · 19 points · 18 days ago
Yeah, Poland rules are not global.
comment on retention time shifted 0.4 min and nobody wants to talk about it in c/hplc · 58 points · 19 days ago
A shoulder on the main peak that 23 analysts integrated 36 different ways. Same trace, 99.2 spread.
comment on method development — 10 things I got wrong before I got it right in c/hplc · 34 points · 27 days ago
Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.
comment on what would you tell week-1 you about EMS in c/intlshipping · 51 points · 29 days ago
Disagree. What you are describing is consistent with carrier, not with what you concluded.

PBS listings change the cost completely
comment on [Vendor] WXT order #24 — France, 29 days, no drama, receipts inside in c/glp1aus · 11 points · 3 months ago
This is the "correlation is mechanism" thing again. You changed three variables at once.

the 2024 compounding rule change closed a major route overnight
comment on 8 months in and transit time is still the thing I get wrong in c/intlshipping · 4 points · 4 months ago
Ireland to Ireland: SSA with 19 days is the average, variance is 31
comment on France: chromatogram, and what it actually costs here in c/hplc · 8 points · 4 months ago
This is the correct method framing.
Adding to this: method development is doing more work than the comment implies.
comment on [Question] Poland — has anyone got a straight answer on EMS in c/intlshipping · 97 points · 5 months ago
This is correct. Variance is the story.
comment on reading purity threads from 2024 and half of it aged badly in c/hplc · 64 points · 5 months ago
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
comment on [Results] 17 weeks, 10kg, and LC-MS was the hard part in c/hplc · 1 points · 5 months ago
instrument quality is less important than analyst consistency
comment on [Question] chromatogram — what am I missing here in c/hplc · 144 points · 5 months ago
Yeah, the chromatogram profile matters more than the headline number.
comment on [Results] 6 weeks on 0.25mg, full numbers, ask me anything boring in c/glp1aus · 15 points · 5 months ago
the 2024 compounding rule change closed a major route overnight
comment on [Question] Ireland — has anyone got a straight answer on weekly update in c/dosinglogs · 65 points · 6 months ago
include dose and date on every update
