Overview — page 4 of 5

comment on three years of purity threads, summarised so you do not have to read them in c/hplc · 0 points · 1 year ago

Did they post the raw trace or just the summary?

comment on [Discussion] chromatogram is doing more work than we give it credit for in c/hplc · 134 points · 1 year ago

Injection volume and flow rate? Those affect resolution.

comment on week 96 check-in — 26kg down, fatigue manageable, one thing confusing me in c/hplc · 49 points · 1 year ago

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

state the method: column, gradient, detection wavelength, injection volume

comment on help me understand waist, I have read the wiki twice in c/dosinglogs · 10 points · 1 year ago

Strongly agree. Update rather than repost.

comment on week 61 check-in — 17kg down, fatigue manageable, one thing confusing me in c/hplc · 6 points · 1 year ago

Flair changed to match the content. Read the sidebar before posting next time and we are square.

comment on [Question] how do you actually verify external review in c/insurancefights · 3 points · 1 year ago

Titration speed is a side-effect dial far more than an efficacy dial.

comment on [Meta] proposal — a flair for formulary posts in c/insurancefights · 20 points · 1 year ago

External review overturned the denial. Took 3 weeks but the process exists.

comment on why does nobody talk about weekly update in c/dosinglogs · 393 points · 1 year ago

Yeah, the consistency is the value.

comment on purity — 8 things I got wrong before I got it right in c/hplc · 53 points · 1 year 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 why does nobody talk about weight in c/dosinglogs · 16 points · 1 year ago

Second this question. I have wondered about waist for 22 months and never seen a straight answer.

comment on denial: what the trials say vs what this community says in c/insurancefights · 116 points · 1 year ago

Small correction: the trial was 22 weeks, not 12. Does not change your point but people will quote it.

comment on am I the only one who found gradient harder than the injections in c/hplc · 459 points · 1 year ago

Removed a chain here. The rule is one line long and it is not negotiable.

comment on survodutide vs hepatic fat — genuinely asking which matters more in c/survodutide · 1 points · 1 year ago

glucagon injection is a different vector than GLP-1

phase 18 data is interesting, phase 18 will be different

comment on Spain: LC-MS, and what it actually costs here in c/hplc · 96 points · 1 year ago

The practical rule people converge on is 28 days at fridge temperature after first puncture, and that comes from the preservative, not the peptide.

comment on Spain: LC-MS, and what it actually costs here in c/hplc · 7 points · 1 year ago

Disagree. What you are describing is consistent with chromatogram, not with what you concluded.

comment on [Question] Ireland — has anyone got a straight answer on method development in c/hplc · 164 points · 1 year ago

Tracking number removed. It identifies both ends of a shipment.

comment on [Vendor] WXT order #9 — the Netherlands, 17 days, no drama, receipts inside in c/insurancefights · 15 points · 1 year ago

prior auth criteria are state-specific, appeal differs
