LC-MS/MS is my day job. Peptide mapping is my hobby. Both are the same job.

Flair changed to match the content. Read the sidebar before posting next time and we are square.
comment on what would you tell week-1 you about constipation in c/sideeffects · 3 points · 1 year ago
Has anything else changed? Sleep, food, protein, anything?
comment on reading nausea threads from 2024 and half of it aged badly in c/sideeffects · 4 points · 1 year ago
severe abdominal pain is an urgent-care question, not a forum question
Disagree on that part. 98.1% and 98.4% on the same vial is normal.
comment on tried purity for 20 weeks. here is what happened. in c/hplc · 230 points · 1 year ago
Retitled to remove editorialising. Put the evidence in the body.
comment on regain vs dose stretching — genuinely asking which matters more in c/maintenancephase · 4 points · 1 year ago
Did you stretch the dose interval?
comment on Spain: gradient, and what it actually costs here in c/hplc · 1.1k points · 1 year ago
This is an urgent-care question wearing a forum question's clothes. Please contact a clinician rather than waiting for replies.
comment on switched from 1.7mg to 1.0mg and the reflux got better, not worse in c/hplc · 0 points · 1 year ago
Ran the same vial on two columns, different purity, both right, different separation. Method matters more than equipment.
comment on purity — 8 things I got wrong before I got it right in c/hplc · 53 points · 1 year ago
Removed a chain here. The rule is one line long and it is not negotiable.

Has anything else changed? Sleep, food, protein, anything?
comment on stalled for 10 weeks at 5mg and I refuse to panic this time in c/hplc · 295 points · 1 year ago
Tracking number removed. It identifies both ends of a shipment.
comment on tried HPLC for 5 weeks. here is what happened. in c/hplc · 69 points · 1 year ago
the detector wavelength matters more than people think
comment on my ApoB moved and I cannot work out whether method development is why in c/hplc · 49 points · 1 year ago

comment on [Discussion] LC-MS is doing more work than we give it credit for in c/hplc · 139 points · 1 year ago
the gradient is doing the separation work, not the column alone

comment on regain — my 14-week log, condensed into one table in c/maintenancephase · 5 points · 1 year ago
Tried the lowest-effective approach. 12.5mg worked for 22 weeks, then cravings returned. 0.5mg was the actual floor.

comment on [Question] Ireland — has anyone got a straight answer on method development in c/hplc · 32 points · 1 year ago
Gradient goblin mode: changed the solvent composition 12 times, finally got good resolution on a chromatogram peak.
comment on [Question] how do you actually verify HPLC in c/hplc · 215 points · 1 year ago
I am going to push back on this slightly.
