comment on transit time — 12 things I got wrong before I got it right in c/intlshipping · 29 points · 2 years ago
Do they publish a reship policy, and did you read it before ordering?
comment on [Lab] 16th independent test on ERP — 97.4% on a claimed 97.0%, and the trend is the interesting part in c/hplc · 23 points · 2 years ago
Resolution between two peaks depends on retention, selectivity and efficiency.
Disagreeing with this bit: that spread is ordinary inter-lab variance, not a disagreement about the material.
comment on [Meta] the tirzepatide rule is doing its job and people should stop complaining in c/tirzepatide · 87 points · 2 years ago
Yes — 10mg being a genuine landing place for a lot of people is underrated. There is no medal for 15.
comment on reading transit time threads from 2024 and half of it aged badly in c/intlshipping · 31 points · 2 years ago
a quoted lead time you can hold them to is worth more than a fast one you cannot
comment on [Question] how do you actually verify gradient in c/hplc · 0 points · 2 years ago
That figure cannot be quoted to two decimals off that baseline. The precision is not in the data.
comment on reship — 8 things I got wrong before I got it right in c/intlshipping · 18 points · 2 years ago
Same. ERP quoted 18 days on my lane and it landed at 8, which is exactly what you want from a quote.
comment on reship — 8 things I got wrong before I got it right in c/intlshipping · -24 points · 2 years ago
Ordered from the warehouse in Spain instead of origin and the whole customs question disappeared. 11 days, door to door.
comment on reship — 8 things I got wrong before I got it right in c/intlshipping · 324 points · 2 years ago
a lane with four reports is not yet a lane
comment on [Lab] 18th independent test on SWB — 99.4% on a claimed 99.0%, and the trend is the interesting part in c/hplc · 262 points · 2 years ago
This. A shoulder that does not baseline-resolve is a question, not a quantity.
comment on how much of what we believe about HPLC actually comes from gradient threads in c/hplc · 1 points · 2 years ago
system suitability before you believe any number on the run
comment on [Discussion] we are measuring GIP at the wrong time and calling it noise in c/tirzepatide · 135 points · 2 years ago
Correction to my own post above — I said 5mg and I have been on 5mg since the spring. Same argument, wrong number.
comment on [Vendor] QST vs QYB on the same compound, same month — both cleared 99.0% in c/tirzepatide · 57 points · 2 years ago
Not sure that follows. You went up a step and changed your training in the same fortnight.
