19 months in and purity is still the thing I get wrong
Confession thread, sort of. I went from 2.5mg to 1.0mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 15 weeks…

comment on COA vs purity — genuinely asking which matters more in c/coa · 796 points · 8 months ago
Strongly agree. Mass% and area% are answering different questions on the same document.

no "is this good?" without saying what the compound and claimed purity are

Same lab both times?

TGA watches change monthly, follow the list
comment on [Discussion] we are measuring PBS at the wrong time and calling it noise in c/glp1aus · 18 points · 10 months ago
This is correct. PBS listings matter.

This is the correct framing. The COA structure matters as much as the number.

Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.

Did they give you the chromatogram or just the summary line?

Sent one vial to PeptideMeter and VendorInvestigate. 96.8% and 99.1%. Cost me more than the vial did and I would do it again.

comment on ApoB is the most under-discussed thing in c/glp1science in c/bloodwork · 121 points · 11 months ago
Sceptical. If this were true we would see it reflected in the data and we do not.
comment on tried A1c for 9 weeks. here is what happened. in c/bloodwork · 95 points · 1 year ago
Half-life is about 168 hours, so steady state lands around week 3–5. Practical consequence: what you feel in week 1 is not what that dose does.
comment on does batch actually matter or is it forum lore at this point in c/coa · 1 points · 1 year ago
purity and net content are two different numbers, same vial

Are you looking at area% or net peptide content? Different numbers.
comment on step therapy — my 7-week log, condensed into one table in c/insurancefights · -2 points · 1 year ago
External review overturned the denial. Took 19 weeks but the process exists.
