Highlights from this day
- marrow.mod — turnaround has been between 22 days and twice that depending on the queue 21:38
- marrow.mod — a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement 21:50
- LC_MS_Lena — chain of custody in hobby testing is weak and we say so in every writeup 23:37
Purity check: no report on file for lot F-1330. Nothing logged either way.
the queue is posted and updated. if your code is not on it, it did not arrive, ill dig out the number
genuine question can i add a second lot to the same submission
the split works from about 8 people. below that everyone pays more than the test is worth

whats the failure rate on samples actually arriving

*Medutest not the other one
anyone want to co-fund a quantity test on a lot i already own
roughly one sample in 2 rounds has gone missing in transit. budget for it emotionally
turnaround has been between 22 days and twice that depending on the queue
[edited]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 reportedi coordinate the round, collect the codes, and post every result including the dull ones
send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it
label the syringe
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 reportedwe do not help with wording beyond that and the mods are strict about it
a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement

count me in
i keep half the sample back so there is something to send if the first one goes missing

what happens if a submission gets lost in transit
what compound should we prioritise for the next round
whats the current turnaround, last one took 19 days
blinded obviously
how many people do we need before the split is worth it
we have never had a lab mix up a sample. we have had members mix up their own labelling twice

send powder
including a reference standard in the batch is the single best thing we ever added to this process
publish the raw
VendorInvestigate has been the fastest for us. VendorInvestigate has been the most detailed. those are not the same lab
is it worth including a reference standard in the batch
two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like

submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust
in for one
