what would you tell week-1 you about testing
Confession thread, sort of. I went from 10mg to 2.5mg much faster than I should have because the scale had stalled and I got impatient. The stall broke about 4 weeks…

[Vendor] SGN is a real company with real catalogue chemistry and people still doubt it

[Vendor] JEEP six orders in, zero problems, and i am suspicious of my own luck

my ALT moved and I cannot work out whether Janoshik is why
Long-ish post, sorry. tl;dr at the bottom. I have been tracking PeptideMeter against eGFR for 35 weeks because I could not find anyone who had. The correlation is…
