comment on [Question] how do you actually verify heart rate in c/sideeffects · 46 points · 8 months ago
reflux at night, try not eating in the three hours before bed
comment on does New Zealand actually matter or is it forum lore at this point in c/glp1aus · 19 points · 9 months ago
What did the pharmacy quote for the private price?

Area percent is the integrated area of your peak over the total integrated area at one wavelength on one gradient. Change any of those and the number changes without the sample changing.

comment on [Meta] proposal — a flair for gradient posts in c/hplc · 22 points · 11 months ago
Not convinced by that integration. Dropping the baseline there absorbs part of the shoulder into the main peak.
comment on someone explain HPLC to me like I have not read a paper in years in c/hplc · 549 points · 1 year ago
Sent the same vial to Medutest and PeptideMeter. 98.4% against a claimed 98.0%. The difference was the gradient, not the material.
comment on [Question] is 97.4% actually fine or am I being sold a rounding error in c/hplc · 94 points · 1 year ago
baseline choice is a decision, not a measurement
comment on does method development actually matter or is it forum lore at this point in c/hplc · 43 points · 1 year ago
This.
Agreed. And the corollary is that the method line on a certificate is not decoration, it is the number’s provenance.

How old is the column and roughly how many injections has it seen?
comment on does method development actually matter or is it forum lore at this point in c/hplc · 65 points · 1 year ago
a blank injection between samples costs four minutes and settles most arguments
comment on unpopular opinion: most of what gets said here about compounding is guesswork in c/glp1aus · 59 points · 1 year ago
The compounded arrangements changed while I was mid-thread and I was arguing from a superseded position.
comment on [Discussion] can we stop arguing about constipation until somebody posts a number in c/sideeffects · 2 points · 1 year ago
holding a dose an extra month is a legitimate answer to bad tolerance
comment on reading New Zealand threads from 2024 and half of it aged badly in c/glp1aus · 65 points · 1 year ago
keep the script and the receipt for private health claims
comment on [PSA] gallbladder is not what most of this community thinks it is in c/sideeffects · 1 points · 1 year ago
Disagree. Severe abdominal pain is not on the list of things to wait out, and this board should not be treating it as one.
comment on [Lab] WXT cagri — PeptideMeter came back 97.8% against a claimed 97.0% in c/hplc · -6 points · 1 year ago
reproducibility beats resolution if you only get one of them
comment on nobody warned me about sulphur burps and I would have liked the warning in c/sideeffects · 9 points · 1 year ago
That reads like advice, and none of us can give it. Describe what you did, not what somebody else should do.
comment on help me understand heart rate, I have read the wiki twice in c/sideeffects · -14 points · 1 year ago
Most of the common complaints trace back to slowed gastric emptying — early fullness, reflux, nausea after a large or fatty meal. That is also why meal size and speed change the experience more than anything else.
comment on [Question] chromatogram — what am I missing here in c/hplc · 22 points · 1 year ago
Do you have the mass, or only the UV trace?
comment on the Netherlands: private plan, and what it actually costs here in c/glp1canada · 1 points · 1 year ago
Have you asked the pharmacist to check?
comment on [Lab] MKM cagri — Medutest came back 97.2% against a claimed 97.0% in c/hplc · 167 points · 1 year ago
Method questions stay here; supplier claims go to c/vendorvetting with a document attached.
mass_spec_maggie is right — the integration choice is a decision and it should be stated alongside the result.
comment on [Lab] MKM cagri — Medutest came back 97.2% against a claimed 97.0% in c/hplc · 11 points · 1 year ago
Gave the same trace to two people I trust and got two integrations about a point apart. That was the most educational afternoon I have had here.
comment on gallbladder — 15 things I got wrong before I got it right in c/sideeffects · 182 points · 1 year ago
Disagreeing with this one line: that symptom is not on the wait-and-see list and should not be posted as though it is.
ipamorelin_i is right about the timing. The day-of-week pattern is the diagnostic bit, not the severity.
comment on [Question] special authorization — what am I missing here in c/glp1canada · 138 points · 1 year ago
A rejected claim at the pharmacy counter and a denied authorization are different events with different remedies. The first can be an administrative or quantity issue; the second is a determination you can appeal.

comment on method development is the most under-discussed thing on this board in c/hplc · 70 points · 2 years ago
Push back: a longer run is not automatically better resolution. You are trading peak width for time and the ratio is what matters.
comment on three years of special authorization threads, summarised so you do not have to read them in c/glp1canada · 0 points · 2 years ago
Employer-sponsored plans have their own criteria and appeal processes, independent of the provincial formulary. Which one applies determines everything about the route.
comment on [Question] is 94.2% actually fine or am I being sold a rounding error in c/hplc · 125 points · 2 years ago
What wavelength, and what was the gradient?
