Area% is not mass%. I will keep saying this until the sun goes out.

comment on glucagon — 17 things I got wrong before I got it right in c/survodutide · 29 points · 2 months ago
This is correct. Do not generalise from tirzepatide.
comment on why does nobody talk about chromatogram in c/hplc · 55 points · 2 months ago
Flair changed to match the content. Read the sidebar before posting next time and we are square.
comment on am I the only one who found hepatic fat harder than the injections in c/survodutide · 4 points · 2 months ago
Australia here. Waited 3 months on a list, gave up, went private, and the total cost was roughly what I expected.

Retitled to remove editorialising. Put the evidence in the body.
comment on anyone else notice prior authorization kicking in around week 69 in c/insurancefights · 38 points · 2 months ago
Poland plan: step therapy required 8 medications first. Did them all, got approval. The order matters.
comment on 6 months in and gradient is still the thing I get wrong in c/hplc · 203 points · 2 months ago
Tracking number removed. It identifies both ends of a shipment.
comment on what would you tell week-1 you about biopsy in c/survodutide · 11 points · 3 months ago
Yeah, glucagon co-agonism is genuinely different.
comment on what would you tell week-1 you about LC-MS in c/hplc · 62 points · 3 months ago
state the method: column, gradient, detection wavelength, injection volume
comment on help me understand chromatogram, I have read the wiki twice in c/hplc · 2 points · 3 months ago
Slight fix: the number was 99.1, not 99.2. Decimal point, but a fairly consequential one.

Removed a chain here. The rule is one line long and it is not negotiable.
comment on 8 months in and HPLC is still the thing I get wrong in c/hplc · 545 points · 4 months ago

comment on biopsy is the most under-discussed thing in c/bloodwork in c/survodutide · 6 points · 4 months ago
Which trial arm?
comment on [Question] Australia — has anyone got a straight answer on hepatic fat in c/survodutide · 6 points · 4 months ago
Yeah, glucagon co-agonism is genuinely different.
comment on [Meta] proposal — a flair for dose history posts in c/dosinglogs · 15 points · 5 months ago
My version of this: I was so worried about the injection that I put it off for eleven days. The injection is the easiest part.
comment on reading purity threads from 2024 and half of it aged badly in c/hplc · 228 points · 5 months ago
Respectfully this is a sample of one presented as a finding.
comment on [Results] 17 weeks, 10kg, and LC-MS was the hard part in c/hplc · 6 points · 5 months ago
Detection wavelength? HPLC and that changes at different wavelengths.
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
