Highlights from this day
- taper_or_not — has anyone ever offered to pay for verification 12:43
- area_percent — how do you handle a result that is good but the sample handling was poor 13:27
- secretagogue_sy — what actually counts as evidence for a verification 14:59
- secretagogue_sy — verification is revoked on a confirmed failure and the revocation stays in the log permanently 15:07
if the evidence is thin the entry says the evidence is thin. that is more useful than a score
[edited]i have a result but i did not buy the lot myself, does that count
two labs a point or two apart on one lot is normal. both go in the log with both numbers
a verified supplier can still ship you a bad vial. verification is about the record, not about your parcel
we refresh on new evidence, not on a clock. an old verification with no recent results says so on the entry
why is a referral link disqualifying rather than just ignored
| Evidence | Counts? |
|---|---|
| Independent report, lot you bought, lot number legible | yes |
| Independent report, no lot number | no |
| Supplier certificate only | no |
| Screenshot of a report | no |
| Blinded pooled submission | yes, for the pool |
| A friend who said it was fine | no |
the log is readable chronologically and that is deliberate. the trajectory matters more than the current line, ill dig out the number
post the photos
revoked stays in the log
pattern not one result
has anyone ever offered to pay for verification

blinded is better
does a good result from PeptideMeter outweigh a bad one from Medutest
i have watched this standard hold for three years including when it was inconvenient for a popular supplier

we have never revoked on a single result. we have revoked on a pattern
✅7🙏3🎉5
a referral link is disqualifying because it makes the reporter an interested party. that is all
genuine question the point of the standard is that it applies to suppliers we like as well as ones we do not

two labs disagree on the same lot, which one goes in the log
what happens to the log entry when a supplier improves
how long does a verification stay current before it needs refreshing
nothing gets deleted
how do you handle a result that is good but the sample handling was poor

is a screenshot of a report ever acceptable
if the evidence is thin the entry says the evidence is thin. that is more useful than a score
both numbers go in
lot number or nothing
a lot number mismatch between the vial and the certificate is a serious finding. post it with photos of both
update on the earlier thing verification is not a recommendation. it means the evidence standard has been met, nothing more
a supplier improving shows in the log as later entries, not as earlier entries being edited
coming back after 12 months, has the standard changed
is there a version of the log i can read chronologically
unrelated but do blinded submissions carry more weight than open ones
the mods maintain the log. the room supplies the evidence and argues about it, which is the correct division
the lot number on the certificate does not match my vial, what now
what actually counts as evidence for a verification

sorry to jump in nothing gets deleted from the log, including our own mistakes

update from 8 months ago: QSC added evidence and the entry now reflects it
not a recommendation
Channel stats, last 30 days: 39 messages from 25 members.
if you want to help, buy a lot, test it, and post the report with the lot number. that is the whole contribution
blinded submissions carry more weight because they remove a variable, not because we distrust the labs
[edited]log it either way
genuine question verification has never been for sale and never will be. offers get posted publicly with the sender redacted
how many independent results does a supplier need
update on the earlier thing what counts: an independent report, on a lot you bought yourself, with the lot number, from a lab the room recognises
is the verification log the same thing as a recommendation
