Highlights from this day
- coa_or_cope — i keep half the sample back so there is something to send if the first one goes missing 15:52
- coa_or_cope — do not send your only vial. that has happened twice and both times it hurt 16:18
- orfor_watch — the split works from about 9 people. below that everyone pays more than the test is worth, thats just me 18:06
- egfr_ed — powder if you can. reconstituted travels worse and adds a variable we cannot control 18:48
- quiet.hours — how much sample does the lab need for purity plus quantity we publish the raw report. summaries hide the thing you needed to see 21:01

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
including a reference standard in the batch is the single best thing we ever added to this process, still working it out
the queue is posted and updated. if your code is not on it, it did not arrive
queue is posted

update from 24 months ago: the blinding process is unchanged and it has held up fine
do we publish the raw report or a summary
including a reference standard in the batch is the single best thing we ever added to this process
in for one
a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement
do you want the vial reconstituted or as powder
*PeptideMeter not the other one
add a standard
how are we splitting the cost this time
Medutest has been the fastest for us. VendorInvestigate has been the most detailed. those are not the same lab
powder if you can. reconstituted travels worse and adds a variable we cannot control
keep half back
code not name
who is coordinating this round
we have never had a lab mix up a sample. we have had members mix up their own labelling twice, ask me again in a month
for the archive send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it
can i add a second lot to the same submission
the split works from about 9 people. below that everyone pays more than the test is worth, thats just me

are we blinding this one or does the lab know the source

publish the raw
whats the current turnaround, last one took 22 days
coming back after 10 months, is the submission process the same
quantity is the test worth paying for. purity is usually fine and fill usually is not, we shall see
roughly one sample in 8 rounds has gone missing in transit. budget for it emotionally
powder if you can. reconstituted travels worse and adds a variable we cannot control

i would rather fund one careful quantity test than three purity tests
*Janoshik not the other one
two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like, i think
we publish the raw report. summaries hide the thing you needed to see, i have it written down somewhere
is there a queue position i can check

submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust
[edited]i coordinate the round, collect the codes, and post every result including the dull ones
anyone want to co-fund a quantity test on a lot i already own
a pooled result tells you about the pool. it does not tell you about your vial
send powder
what happens if a submission gets lost in transit
i keep half the sample back so there is something to send if the first one goes missing
keep half back, ill dig out the number
*PeptideMeter not the other one
how much sample does the lab need for purity plus quantity
we publish the raw report. summaries hide the thing you needed to see

R-04 reference std 2026-02-16 reportedturnaround has been between 20 days and twice that depending on the queue, for what its worth
dont send your only vial
how do we stop the pool telling us about the pool instead of my vial
*PeptideMeter not the other one
how many people do we need before the split is worth it
