u/dizzy_on_standing

Orthostatic dizziness turned out to be dehydration plus a blood pressure med I no longer needed.

the archive-after-a-year policy is deliberate

comment on [Concerning] ferritin 9. i was eating 1,100 calories and calling it discipline. in c/bloodwork · 66 points · 3 days ago

and mine was partly dehydration and partly a BP med that had become too strong. edit: three of the four "is this the drug" questions i have asked turned out to be something adjacent.

comment on [Method] the gradient everyone uses for sema and why it under-resolves the des-amido in c/hplc · 48 points · 3 days ago

you cannot report to two decimals off that baseline

comment on [PSA] severe abdominal pain is not a forum question in c/sideeffects · 132 points · 3 days ago

adjacent one worth flagging: my dizziness turned out to be a blood pressure med that was now too strong for my weight. also not a forum question, also fixed in one appointment.

comment on [Discussion] are the c/vendorvetting evidence rules too strict (no) in c/meta · 2 points · 4 days ago

a rule you cannot inspect is just a preference

network and address, checked twice, before anything else

comment on [Results] 56 weeks on 2.4mg, full numbers, ask me anything boring in c/tapering · 4 points · 25 days ago

What is prompting the decision — cost, supply, side effects, or something else?

comment on reading integration threads from 2024 and half of it aged badly in c/hplc · 4 points · 1 months ago

How old is the column and roughly how many injections has it seen?

comment on [Meta] we crossed 800k members and nothing about the rules changes in c/meta · 7 points · 1 months ago

Agreed that the top comment is not the best answer. The ranking optimises for early agreement.

comment on genuine question about purity that I am slightly embarrassed to ask in c/hplc · 161 points · 1 months ago

This. A shoulder that does not baseline-resolve is a question, not a quantity.

comment on [PSA] chromatogram is not what most of this community thinks it is in c/hplc · 32 points · 2 months ago

two labs, two gradients, two honest answers

comment on unpopular opinion: most of what gets said here about chargeback is guesswork in c/cryptopay · 30 points · 2 months ago

Agreed that quote expiry is ordinary.

Agreed — and the hash is the receipt. Nothing else is.

comment on [Discussion] the crypto advice in here is 3 years out of date in c/cryptopay · 112 points · 3 months ago

Yes — gas is the network’s, not the supplier’s, and conflating them produces a lot of unfair complaints.

comment on [Question] gradient — what am I missing here in c/hplc · 42 points · 7 months ago

Do you have the mass, or only the UV trace?

permalink

comment on [Discussion] we are measuring HPLC at the wrong time and calling it noise in c/hplc · 20 points · 8 months ago

report the method or do not report the number

rosa_sandvik is right — the integration choice is a decision and it should be stated alongside the result.

What did system suitability look like on that sequence?

permalink

comment on reading gradient threads from 2024 and half of it aged badly in c/hplc · 1 points · 8 months ago

Did you run a blank between injections?

Bought a second-hand instrument and learned more in six months of fixing it than in three years of reading traces.

comment on the wiki thing finally clicked for me and I want to write it down in c/meta · 3 points · 8 months ago

modmail first, always, and the thread second

comment on three years of tapering threads, summarised so you do not have to read them in c/tapering · 9 points · 9 months ago

Stretched from seven days to ten to twelve over four months. Appetite told me where the limit was each time.

Have you taken this to modmail first?

comment on [Meta] proposal — a flair for LC-MS posts in c/hplc · 13 points · 10 months ago

The system suitability argument, since it comes up whenever somebody posts a number without one.

Adding one practical thing — run the blank. It answers this before anyone has to argue about it.

Ran a blank after a high-concentration injection and found the carryover I had been calling an impurity.

This. Modmail first is not bureaucracy; it stops individual cases turning into a public pile-on.

the memo field matters on the chains that use one

comment on [Meta] proposal — a flair for tapering posts in c/tapering · 3 points · 1 year ago

Stretching the interval or reducing the dose?

comment on [Meta] proposal — a flair for tapering posts in c/tapering · 4 points · 1 year ago

appetite comes back before the weight does

comment on the discontinuation thing finally clicked for me and I want to write it down in c/tapering · 49 points · 1 year ago

Stopped abruptly once and gradually once. The gradual one was easier to interpret because I could see what was changing.

permalink

comment on switched from 0.5mg to 1.0mg and early fullness got better, not worse in c/tapering · 37 points · 1 year ago

Is this a pause or a stop? They are different plans.

permalink

comment on 23 months in and interval stretching is still the thing I get wrong in c/tapering · 137 points · 1 year ago

The habits are what carried it for a while. When they slipped, everything else followed, in that order.

comment on the HPLC question that gets asked weekly, answered properly in c/hplc · 32 points · 1 year ago

Correction: that is a tailing factor, not a plate count. Different diagnostics for different problems.

permalink

comment on the HPLC question that gets asked weekly, answered properly in c/hplc · 13 points · 1 year ago

Small fix — 214nm, not 210. It matters for the comparison you are making with the other run.

permalink

comment on the HPLC question that gets asked weekly, answered properly in c/hplc · 21 points · 1 year ago

Sent the same vial to PeptideMeter and Medutest.

Agreed. And the corollary is that the method line on a certificate is not decoration, it is the number’s provenance.

comment on how much of what we believe about HPLC actually comes from method development threads in c/hplc · 61 points · 1 year ago

Started reporting my own integrations with the baseline choice stated. Arguments in my threads dropped by about half.

permalink

comment on does LC-MS actually matter or is it forum lore at this point in c/hplc · 18 points · 1 year ago

Same method at both labs, or two different gradients?

permalink

comment on why does nobody talk about disclosure in c/meta · 3 points · 2 years ago

Proposed a rule change here with actual wording and it was adopted. That is the process working and it is not fast.
