Highlights from this day
*PeptideMeter not the other one
a pooled result tells you about the pool. it does not tell you about your vial
unrelated but the queue is posted and updated. if your code is not on it, it did not arrive

how many people do we need before the split is worth it
unrelated but quantity is the test worth paying for. purity is usually fine and fill usually is not
declare it as an analytical reference sample with a low value. that is what it is, happy to be corrected
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 reportedwhats the split
we do not help with wording beyond that and the mods are strict about it
*VendorInvestigate not the other one
a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement

how long do you keep the retained half of the sample
⚠️11❤️8📉15
for the archive roughly one sample in 7 rounds has gone missing in transit. budget for it emotionally, someone check my working
queue is posted

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

R-04 reference std 2026-02-16 reportedadd a standard
powder if you can. reconstituted travels worse and adds a variable we cannot control
update from 5 months ago: the blinding process is unchanged and it has held up fine
blinded obviously
VendorInvestigate has been the fastest for us. VendorInvestigate has been the most detailed. those are not the same lab

*PeptideMeter not the other one
if you want to know about your vial, you have to submit your vial. that is the whole answer
is there a submission going out this month and can i get in on it
do you want the vial reconstituted or as powder
Batch lookup B-0114: 8 independent reports on file, earliest 2025-03-05.
i coordinate the round, collect the codes, and post every result including the dull ones
i would rather fund one careful quantity test than three purity tests
two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like
code not name
while im here do not send your only vial. that has happened twice and both times it hurt
✅8😂8
we have never had a lab mix up a sample. we have had members mix up their own labelling twice
dont send your only vial
how are we splitting the cost this time
chain of custody in hobby testing is weak and we say so in every writeup
we publish the raw report. summaries hide the thing you needed to see
coordinating this round
including a reference standard in the batch is the single best thing we ever added to this process
Purity check: no report on file for lot C-4402. Nothing logged either way.
do i send a syringe or the whole vial
queue is posted
whats the failure rate on samples actually arriving
📉12😂5🙏5
while im here the split works from about 5 people. below that everyone pays more than the test is worth
turnaround has been between 9 days and twice that depending on the queue
i keep half the sample back so there is something to send if the first one goes missing
