Highlights from this day
  • reta_resting_hr — water content is why an honest 10mg vial assays at 9.1. karl fischer titration, and most certificates omit it, from memory 15:08
  • reta_resting_hr — is there a standard layout or does every lab do their own 15:09
  • reta_resting_hr — i asked JEEP for the method and they sent it. that alone put them ahead of most 15:12

the related substances table is the interesting part. a row of "not detected" means they did not look hard

purity is not assay

i asked JEEP for the method and they sent it. that alone put them ahead of most

tfa or acetate, how do i tell from the paperwork

update from 16 months ago: started asking every supplier for water content and about half now include it

if the certificate date precedes the lot date, ask. sometimes it is sloppiness and sometimes it is not

i keep every certificate in a dated folder and compare them. two suppliers had not changed their template since 2019
