Highlights from this day
  • knees_first — right so Medutest has been the fastest for us. VendorInvestigate has been the most detailed. those are not the same lab, ill dig out the number 22:30
  • lena_lots — quick one is there a submission going out this month and can i get in on it 22:37
  • VialBot — Purity check: no report on file for lot C-4402. Nothing logged either way. 22:44
  • knees_first — the split works from about 9 people. below that everyone pays more than the test is worth 22:45

roughly one sample in 6 rounds has gone missing in transit. budget for it emotionally

count me in

blinded obviously

coordinating this round

can i add a second lot to the same submission

quick one is there a submission going out this month and can i get in on it

how much sample does the lab need for purity plus quantity

KF

if you want to know about your vial, you have to submit your vial. that is the whole answer

unrelated but what compound should we prioritise for the next round

VB

Purity check: no report on file for lot C-4402. Nothing logged either way.

the split works from about 9 people. below that everyone pays more than the test is worth

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

what happens if a submission gets lost in transit

BN

i would rather fund one careful quantity test than three purity tests

turnaround has been between 12 days and twice that depending on the queue

BN

how do we stop the pool telling us about the pool instead of my vial

AA

powder if you can. reconstituted travels worse and adds a variable we cannot control

we publish the raw report. summaries hide the thing you needed to see

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

add a standard

LM

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

including a reference standard in the batch is the single best thing we ever added to this process

label the syringe

how long do you keep the retained half of the sample

send powder

do we publish the raw report or a summary

CO

chain of custody in hobby testing is weak and we say so in every writeup, ymmv

i coordinate the round, collect the codes, and post every result including the dull ones

[edited]
LM

do not send your only vial. that has happened twice and both times it hurt

do you want the vial reconstituted or as powder

i keep half the sample back so there is something to send if the first one goes missing

update from 13 months ago: the blinding process is unchanged and it has held up fine

two labs on the same lot is a luxury but it is how we learned what inter-lab variance looks like
