update from 7 months ago: retested the same supplier, result came back better, logged both
#test-results 2026-04-30
- nausea_window — is anyone tracking results over time in a way they would share 11:07
- split_shipment — what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern 11:28
- split_shipment — the honest limits: hobby chain of custody is weak and any result here should be read with that in mind 13:19
- nausea_window — my read after three years of this: purity is mostly fine across the market and fill consistency is where suppliers differ 14:16
is anyone tracking results over time in a way they would share
| 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 |
has a supplier ever disputed a result posted here
thats within range
how do you separate batch variance from supplier variance
log the boring results too. a channel that only records failures produces a false picture
[edited]what interests me is when the gap goes the same direction every time. once is noise, three times is a pattern
how much does sample handling on my end affect the number
quick one is a purity-only test worth the money if underfill is the common failure
the honest limits: hobby chain of custody is weak and any result here should be read with that in mind
does a bad result on one lot condemn the whole supplier
anyone had a result they think was a lab error rather than a bad vial
my read after three years of this: purity is mostly fine across the market and fill consistency is where suppliers differ
if the vial has been through a bad transit you are testing the transit as much as the supplier, anyway
coming back after 7 months with a follow up result, where do i put it
