what does not count: the supplier certificate alone, a screenshot, a referral link, or a friend who says it was fine

Highlights from this day
- HPLC_Hank — when a number comes back at 96 on a name people like, this channel spends forty lines finding reasons the test was off. when it comes back at 96 on a name people are… 17:39
- meal_prep_mick — that is uncomfortably accurate 17:57
- tarpit_tam — 96 percent purity means 4 percent is something else, and the report tells you whether that something is related peptide or unknown 19:37
- tarpit_tam — report with the header masked, so you can read the trace without knowing who it is 19:42
- lot_number_lou — i am going to defend myself and say 96.4 on retatrutide is harder than 99 on semaglutide. longer chain, more places to go wrong 19:52
lot number or nothing
both numbers go in
genuine question we refresh on new evidence, not on a clock. an old verification with no recent results says so on the entry, not advice obviously
we have never revoked on a single result. we have revoked on a pattern
a verified supplier can still ship you a bad vial. verification is about the record, not about your parcel, ask me again in a month
pattern not one result
post the photos
what happens to the log entry when a supplier improves
thats evidence
slightly off topic but the point of the standard is that it applies to suppliers we like as well as ones we do not
a lot number mismatch between the vial and the certificate is a serious finding. post it with photos of both
proposal, and i have been chewing on it for a month. we blind the vendor name on submission
blind it from who, the lab already does not know
blind it from us. from the channel, until the number is posted
why, the lab does the measuring
because the argument afterwards is where the bias lives, not the measurement
when a number comes back at 96 on a name people like, this channel spends forty lines finding reasons the test was off. when it comes back at 96 on a name people are cold on, nobody questions it at all
that is uncomfortably accurate

i have seen it from the lab side of the conversation. people send a follow-up question only when they dislike the answer
how would it work mechanically
submitter -> mod DM:
vendor, domain, lot, order receipt, lab report
mod posts to channel:
SUBMISSION S-114
compound: retatrutide
label: 10mg
lab: Janoshik
purity: 96.4%
net mass: 9.8mg
vendor: [withheld until 24h]
after 24h the mod posts the vendor name and the log entry ID24 hours of everyone guessing. i can see the appeal and also the chaos
what stops people guessing from the lot format
nothing, lot formats are basically fingerprints. so we withhold the lot for the 24 hours too and publish it with the name
i will run it for a month. if it turns into a guessing game we stop
fair
first one then
SUBMISSION S-114
compound: retatrutide
label: 10mg
lab: Janoshik
purity: 96.4%
net mass: 9.8mg
vendor: [withheld 24h]
lot: [withheld 24h]96.4 is a mediocre number for anyone
it is under the 98 we usually see. no excuses from me either way
is 96 unusable
96 percent purity means 4 percent is something else, and the report tells you whether that something is related peptide or unknown
on this one it is mostly a single related-peptide peak, which is a synthesis or cleavage artefact, not contamination
report with the header masked, so you can read the trace without knowing who it is

the trace is clean apart from the shoulder. that is a real 96, not a messy 96
24 hours up. vendor is Hubei Jianxiang, lot HJX-0603-07
huh. i would have guessed lower down the list
and there it is. that reaction is exactly what the blinding was for
i am going to defend myself and say 96.4 on retatrutide is harder than 99 on semaglutide. longer chain, more places to go wrong
that is technically true and it applies to everyone equally, which is why the blinding does not care
logged as VERIFIED with the number as measured. Jianxiang have five other entries, all 98 plus
so one softer number in six
yes. and if you had seen the name first you would have read that number differently, which is the entire point of the exercise
keeping the blinding then
keeping the blinding. Zhuhai Kerui and Wuhan Wansheng both have submissions in the queue, they go through the same way
