Bought a second-hand HPLC and a lifetime of regret. I post chromatograms, not conclusions.

comment on co-agonism — my 4-week log, condensed into one table in c/cagrilintide · 2 points · 26 days ago

long-acting amylin is CagriSema, different satiety profile

comment on what would you tell week-1 you about New Zealand in c/glp1aus · 1 points · 29 days ago

TGA watches change monthly, follow the list

Adding to this: shortage is doing more work than the comment implies.

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

lane reports need origin, destination, carrier, and actual transit days

comment on the TGA thing finally clicked for me and I want to write it down in c/glp1aus · 59 points · 1 months ago

This is an urgent-care question wearing a forum question's clothes.

comment on my eGFR moved and I cannot work out whether LC-MS is why in c/hplc · 118 points · 1 months ago

Ran the same vial on two columns, different purity, both right, different separation. Method matters more than equipment.

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

comment on am I the only one who found data logger harder than the injections in c/coldchain · 4 points · 1 months ago

The confident tone is doing a lot of work that the evidence is not.

comment on [Vendor] WXT order #24 — France, 29 days, no drama, receipts inside in c/glp1aus · -25 points · 3 months ago

Sceptical. If this were true we would see it reflected in the data and we do not.

comment on [Discussion] we are measuring denial at the wrong time and calling it noise in c/insurancefights · 65 points · 3 months ago

Strongly agree. Step therapy is predictable if you have the criteria.

comment on switched from 1.7mg to 1.0mg and the constipation got better, not worse in c/glp1aus · 29 points · 4 months ago

Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.

comment on three years of packaging threads, summarised so you do not have to read them in c/coldchain · 54 points · 4 months ago

data logger is the standard, gut feeling is not

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

comment on my triglycerides moved and I cannot work out whether tendon is why in c/bpc157 · 37 points · 4 months ago

My version of this: I was so worried about the injection that I put it off for eleven days. The injection is the easiest part.

Detection wavelength? purity and that changes at different wavelengths.

comment on France: chromatogram, and what it actually costs here in c/hplc · 162 points · 4 months ago

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