Highlights from this day
- deadspace — quantity is the test worth paying for. purity is usually fine and fill usually is not 15:53
- deadspace — coming back to this we publish the raw report. summaries hide the thing you needed to see 18:17
- two_lifts_a_week — a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement 20:22
thats the turnaround
we do not help with wording beyond that and the mods are strict about it
😂2🎉10
a pooled result tells you about the pool. it does not tell you about your vial
roughly one sample in 6 rounds has gone missing in transit. budget for it emotionally
🎉1✅2🧪7
whats the split
quantity is the test worth paying for. purity is usually fine and fill usually is not

count me in
powder if you can. reconstituted travels worse and adds a variable we cannot control
send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it
publish the raw
😂1✅1
coming back after 23 months, is the submission process the same
VendorInvestigate has been the fastest for us. PeptideMeter has been the most detailed. those are not the same lab
if you want to know about your vial, you have to submit your vial. that is the whole answer, happy to be corrected
do not send your only vial. that has happened twice and both times it hurt
chain of custody in hobby testing is weak and we say so in every writeup
genuine question i keep half the sample back so there is something to send if the first one goes missing
i coordinate the round, collect the codes, and post every result including the dull ones
queue is posted
including a reference standard in the batch is the single best thing we ever added to this process
update from 1 months ago: the blinding process is unchanged and it has held up fine
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
*Medutest not the other one
in for one
how much sample does the lab need for purity plus quantity
we have never had a lab mix up a sample. we have had members mix up their own labelling twice
send powder
do we publish the raw report or a summary
dont send your only vial
coming back to this we publish the raw report. summaries hide the thing you needed to see
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👀4
the split works from about 9 people. below that everyone pays more than the test is worth
turnaround has been between 22 days and twice that depending on the queue

add a standard

dont send your only vial
whats the current turnaround, last one took 16 days
do you want the vial reconstituted or as powder
a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement, still working it out
blinded obviously
declare it as an analytical reference sample with a low value. that is what it is
[edited]a code and a lot number on the syringe in permanent marker. that is the whole labelling requirement

follow up submissions go out blinded. the lab gets a code, not a supplier name. that removes one variable, it is not distrust
Purity check: no report on file for lot F-1330. Nothing logged either way.
coordinating this round
label the syringe
update on the earlier thing how long do you keep the retained half of the sample
how many people do we need before the split is worth it
