how much sample does the lab need for purity plus quantity
#lab-requests 2026-04-09
can i add a second lot to the same submission
update from 9 months ago: the blinding process is unchanged and it has held up fine
keep half back
declare it as an analytical reference sample with a low value. that is what it is
label the syringe
coordinating this round
thats the turnaround
the queue is posted and updated. if your code is not on it, it did not arrive
publish the raw
*Medutest not the other one
dont send your only vial
genuine question is there a preferred lab for quantity specifically
queue is posted
[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 reportedcode not name
count me in
is there a submission going out this month and can i get in on it
what compound should we prioritise for the next round
do i send a syringe or the whole vial
do not send your only vial. that has happened twice and both times it hurt
i would rather fund one careful quantity test than three purity tests
i keep half the sample back so there is something to send if the first one goes missing
while im here if you want to know about your vial, you have to submit your vial. that is the whole answer, happy to be corrected
whats the wording on the customs declaration for a sample
turnaround has been between 24 days and twice that depending on the queue
how long do you keep the retained half of the sample
who is coordinating this round
quick one send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it
chain of custody in hobby testing is weak and we say so in every writeup
follow up including a reference standard in the batch is the single best thing we ever added to this process
[edited]are we blinding this one or does the lab know the source
the split works from about 5 people. below that everyone pays more than the test is worth
blinded obviously
we do not help with wording beyond that and the mods are strict about it
whats the split
for the archive do you want the vial reconstituted or as powder
we publish the raw report. summaries hide the thing you needed to see
sorry to jump in how do we stop the pool telling us about the pool instead of my vial
*sorry, WWB
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
i keep half the sample back so there is something to send if the first one goes missing
in for one
