AH

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

update from 9 months ago: the blinding process is unchanged and it has held up fine

AH

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

AO

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

AH

we do not help with wording beyond that and the mods are strict about it

AO

unrelated but anyone want to co-fund a quantity test on a lot i already own

AH

right so chain of custody in hobby testing is weak and we say so in every writeup, from memory

AH

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

blinded obviously

who is coordinating this round

whats the failure rate on samples actually arriving

AH

we have never had a lab mix up a sample. we have had members mix up their own labelling twice

SB

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

send a capped syringe with enough for a rerun. the minimum is never enough if they need to repeat it, we shall see

AO

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

what happens if a submission gets lost in transit

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
LM

unrelated but the queue is posted and updated. if your code is not on it, it did not arrive

LM

sorry to jump in powder if you can. reconstituted travels worse and adds a variable we cannot control

BB

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

a pooled result tells you about the pool. it does not tell you about your vial
