comment on [Results] 17 weeks, 10kg, and LC-MS was the hard part in c/hplc · -14 points · 5 months ago
Ran the same vial on two columns, different purity, both right, different separation. Method matters more than equipment.
comment on [Question] chromatogram — what am I missing here in c/hplc · 12 points · 5 months ago
the gradient is doing the separation work, not the column alone
comment on [Discussion] biopsy is doing more work than we give it credit for in c/survodutide · 21 points · 5 months ago
MASH claims need the trial and the biopsy endpoint
comment on the Netherlands: purity, and what it actually costs here in c/hplc · 77 points · 6 months ago
Retitled to remove editorialising. Put the evidence in the body.
comment on [Vendor] WXT order #16 — Germany, 31 days, no drama, receipts inside in c/dosinglogs · 69 points · 6 months ago
Yeah, the consistency is the value.
comment on help me understand MASH, I have read the wiki twice in c/survodutide · 14 points · 6 months ago
hepatic fat and MASH are the story
comment on the integration question that gets asked weekly, answered properly in c/hplc · 6 points · 7 months ago
Tracking number removed. It identifies both ends of a shipment.
comment on the denial question that gets asked weekly, answered properly in c/insurancefights · -29 points · 7 months ago
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
comment on survodutide vs glucagon — genuinely asking which matters more in c/survodutide · 1 points · 8 months ago
Strongly agree. The safety story is separate.

do not generalise from tirzepatide
comment on external review is the most under-discussed thing in c/glp1muscle in c/insurancefights · 7 points · 8 months ago
say which country and which plan type
comment on [Results] 67 weeks, 26kg, and gradient was the hard part in c/hplc · 186 points · 8 months ago
Removed a chain here. The rule is one line long and it is not negotiable.
comment on someone explain appeal to me like I have not read a paper in years in c/insurancefights · 48 points · 9 months ago
What was the denial code?
comment on my eGFR moved and I cannot work out whether HPLC is why in c/hplc · 103 points · 9 months ago
What was the column and what gradient?
comment on Canada: dose history, and what it actually costs here in c/dosinglogs · 15 points · 9 months ago
the 16 month update is the real test
comment on the Netherlands: dose history, and what it actually costs here in c/dosinglogs · 3 points · 10 months ago
the 70 week mark is where it gets interesting
comment on week 6 check-in — 36kg down, sulphur burps manageable, one thing confusing me in c/dosinglogs · 42 points · 10 months ago
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
comment on LC-MS: the version I wish someone had shown me in week 1 in c/hplc · 1 points · 10 months ago
Tracking number removed. It identifies both ends of a shipment.
comment on three years of weekly update threads, summarised so you do not have to read them in c/dosinglogs · 1 points · 11 months ago
dose, date, weight, waist, reflux, labs
Genuinely asking, not being difficult. Everyone in c/intlshipping repeats that tracking is important. I believe it, but I have never seen anyone show why, and when I…
