Overview — page 2 of 3

comment on unpopular opinion: most of what gets said here about COA is guesswork in c/coa · 36 points · 5 months ago

Not quite. Two labs with different gradients can resolve a close-eluting impurity differently and both be reporting honestly.

comment on [Question] tier 3 — what am I missing here in c/glp1uk · 260 points · 5 months ago

Discharge from a specialist service at goal is a normal end point of that pathway. Whether prescribing continues in primary care afterwards is a local decision and is worth asking about at the start rather than at the end.

comment on New Zealand: Canada, and what it actually costs here in c/glp1canada · 58 points · 5 months ago

Quantity limits restrict how much may be dispensed in a period even where coverage exists. They are a distinct barrier and require a distinct request.

comment on [Lab] 10th independent test on ERP — 97.2% on a claimed 97.0%, and the trend is the interesting part in c/coa · 1 points · 6 months ago

post the whole document, not the headline number

Disagree on this specific point. Two honest labs can resolve that impurity differently and report different numbers.

comment on Ireland: Canada, and what it actually costs here in c/glp1canada · 14 points · 8 months ago

Compared cash prices across four pharmacies before pursuing coverage and the spread was larger than I expected.

Yes — median rather than best case. The fastest anybody ever got is not a plan.

comment on my triglycerides moved and I cannot work out whether weekly update is why in c/dosinglogs · 130 points · 9 months ago

Exported the whole thing to a plain text file after nearly losing it in an app that shut down.

comment on weight: the version I wish someone had shown me in week 1 in c/dosinglogs · 10 points · 9 months ago

Added a sleep column late and immediately understood two of my worst weeks.

comment on tracking — 17 things I got wrong before I got it right in c/dosinglogs · 18 points · 10 months ago

annotate the weeks where something else changed

the counterion is part of the mass you paid for

comment on purity — 6 things I got wrong before I got it right in c/coa · 360 points · 1 year ago

Net peptide content is the fraction of the powder that is actually peptide once counterion, water and residual solvent are accounted for. A 99% pure acetate salt can still be about 85% peptide by mass.

comment on [Meta] the shipping rule is doing its job and people should stop complaining in c/intlshipping · 1 points · 1 year ago

ask which lines are actually held in the regional warehouse

comment on [Question] area percent — what am I missing here in c/coa · -32 points · 1 year ago

The PDF creation date being later than the analysis date is usually a re-issue or a re-export. It is worth one question and it is not evidence of anything on its own.

comment on stalled for 8 weeks at 15mg and I refuse to panic this time in c/dosinglogs · 9 points · 1 year ago

Missing entries recorded as blanks preserve the shape of the series. Dropping them silently makes the remaining points look more regular than they were.

comment on is it normal to get food noise at week 63 in c/dosinglogs · 0 points · 1 year ago

waist monthly, weight weekly, notes whenever

Adding the column everyone adds late — sleep. Start with it.

comment on related substances — 9 things I got wrong before I got it right in c/coa · 398 points · 1 year ago

UV at 214nm sees the peptide bond and picks up almost everything; at 280nm you are looking at aromatics only. Which wavelength the number came from is part of the number.

Correcting my own log post above: I had the dose recorded wrongly for one fortnight and have amended it.

Are the missed weeks in there as blanks or dropped entirely?

comment on why does nobody talk about water content in c/coa · 0 points · 1 year ago

The PDF creation date being later than the analysis date is usually a re-issue or a re-export. It is worth one question and it is not evidence of anything on its own.

comment on [Vendor] JEEP order #3 — Ireland, 21 days, no drama, receipts inside in c/intlshipping · 11 points · 1 year ago

Same. SSA quoted 21 days on my lane and it landed at 5, which is exactly what you want from a quote.

comment on help me understand batch, I have read the wiki twice in c/coa · 347 points · 1 year ago

Spent four months confusing area% and mass% in every post I made here. One explainer thread and it clicked permanently.

permalink

comment on [Question] special authorization — what am I missing here in c/glp1canada · 5 points · 1 year ago

Right, and the pharmacist can usually give a definite answer faster than a week of forum speculation.

permalink

comment on help me understand area percent, I have read the wiki twice in c/coa · 92 points · 1 year ago

Pushing back a little: a missing field is usually presentation, not concealment. Ask for the full document before drawing conclusions.

permalink

comment on genuine question about UK that I am slightly embarrassed to ask in c/glp1uk · -7 points · 1 year ago

Which nation, and which ICB if you are in England?

permalink

comment on how much of what we believe about lane actually comes from shipping threads in c/intlshipping · 304 points · 1 year ago

Median transit is the useful statistic. The minimum is a story about one shipment and the mean is dragged around by a single hold.

comment on formulary — 11 things I got wrong before I got it right in c/glp1canada · 21 points · 1 year ago

Read the special authorization criteria and wrote the application against them line by line. Approved first time after a previous refusal.

permalink

comment on genuine question about weekly update that I am slightly embarrassed to ask in c/dosinglogs · 10 points · 1 year ago

Push back: a log with four variables changing at once cannot attribute anything to any of them.

permalink

comment on [Discussion] we are measuring carrier at the wrong time and calling it noise in c/intlshipping · 51 points · 1 year ago

Was it shipped from a regional warehouse or from origin?

runa_wikstrom is right about regional stock. It changes the shape of the distribution, not just the mean.

permalink

comment on [Meta] the Canada rule is doing its job and people should stop complaining in c/glp1canada · 106 points · 1 year ago

Was this a denied authorization or a rejected claim?

Quantity limits restrict how much may be dispensed in a period even where coverage exists. They are a distinct barrier and require a distinct request.

comment on [Lab] split one vial across VendorInvestigate and PeptideMeter — 97.2% and 96.8% in c/coa · 29 points · 1 year ago

Careful — "the metadata looks odd" is a reason to ask a question, not a conclusion. Re-issues are ordinary.
