Highlights from this day
- LC_MS_Lena — i would rather fund one careful quantity test than three purity tests 07:57
- blank_run — is there a queue position i can check 10:13
- blank_run — sorry to jump in is it worth including a reference standard in the batch 11:08
- noct.titrate — send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it 12:25
coming back to this powder if you can. reconstituted travels worse and adds a variable we cannot control
📉4
how much sample does the lab need for purity plus quantity
whats the split
📈3
send powder
coming back after 15 months, is the submission process the same
quick one do you want the vial reconstituted or as powder
count me in
a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement
two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like
we have never had a lab mix up a sample. we have had members mix up their own labelling twice
roughly one sample in 4 rounds has gone missing in transit. budget for it emotionally
ok so the split works from about 9 people. below that everyone pays more than the test is worth
we do not help with wording beyond that and the mods are strict about it
are we blinding this one or does the lab know the source
📈2
do i send a syringe or the whole vial
[edited]i would rather fund one careful quantity test than three purity tests
📉2🧪1🔥13
what compound should we prioritise for the next round
💀12
who is coordinating this round
we publish the raw report. summaries hide the thing you needed to see
submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust
is there a preferred lab for quantity specifically
keep half back
sorry to jump in can i add a second lot to the same submission
anyone want to co-fund a quantity test on a lot i already own
lot-log.csv
359 rows · not retained in the public archive
whats the wording on the customs declaration for a sample
a pooled result tells you about the pool. it does not tell you about your vial
queue is posted
🧪2
code not name
declare it as an analytical reference sample with a low value. that is what it is
*that should say weekly
is there a queue position i can check
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 reporteddo we publish the raw report or a summary
for the archive quantity is the test worth paying for. purity is usually fine and fill usually is not
turnaround has been between 19 days and twice that depending on the queue, n of 1 obviously
i keep half the sample back so there is something to send if the first one goes missing
chain of custody in hobby testing is weak and we say so in every writeup
add a standard
including a reference standard in the batch is the single best thing we ever added to this process
whats the current turnaround, last one took 5 days
whats the failure rate on samples actually arriving
sorry to jump in is it worth including a reference standard in the batch
👀13
how do we stop the pool telling us about the pool instead of my vial
the queue is posted and updated. if your code is not on it, it did not arrive
[edited]how are we splitting the cost this time
dont send your only vial
send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it

in for one
