Highlights from this day

power_cut_pia — i coordinate the round, collect the codes, and post every result including the dull ones 07:49
two_three_lifts — what compound should we prioritise for the next round 09:14
tail_factor — is it worth including a reference standard in the batch 09:23

no_chargeback 07:17

update from 3 months ago: the blinding process is unchanged and it has held up fine

two_three_lifts 07:19

roughly one sample in 4 rounds has gone missing in transit. budget for it emotionally

dont send your only vial

New independent result logged — QSC, lot SG-1177, purity 98.1% (Medutest).

no_chargeback 07:39

coming back after 11 months, is the submission process the same

no_chargeback 07:48

follow up two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like

blind_submit 07:52

can i add a second lot to the same submission

blind_submit 08:22

how much sample does the lab need for purity plus quantity

blank_runlab08:24

do not send your only vial. that has happened twice and both times it hurt

blank_runlab08:32

powder if you can. reconstituted travels worse and adds a variable we cannot control

power_cut_pia 08:33

how are we splitting the cost this time

blind_submit 08:35

queue is posted

blank_runlab08:55

PeptideMeter has been the fastest for us. VendorInvestigate has been the most detailed. those are not the same lab, thats one data point

two_three_lifts 09:14

what compound should we prioritise for the next round

tail_factorlab09:23

is it worth including a reference standard in the batch

code  compound      submitted   status
R-01  semaglutide   2026-02-14  reported
R-02  tirzepatide   2026-02-14  reported
R-03  retatrutide   2026-02-16  in queue
R-04  reference std 2026-02-16  reported

a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement

thats the turnaround

tail_factorlab09:41

blinded obviously

add a standard

how do we stop the pool telling us about the pool instead of my vial
