Overview — page 2 of 5

comment on someone explain LC-MS to me like I have not read a paper in years in c/hplc · 16 points · 1 months ago

Disagree but this is the good kind of wrong — it is specific enough to be checked.

comment on what would you tell week-1 you about HPLC in c/hplc · 11 points · 2 months ago

axis labels included, always

comment on denial — my 12-week log, condensed into one table in c/insurancefights · 6 points · 2 months ago

Yeah, the denial code matters, it tells you what to fight.

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.

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

Retitled to remove editorialising. Put the evidence in the body.

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.
