sample handling on your end absolutely affects it. draw cleanly, ship fast, do not let it sit warm, ymmv

i have never regretted spending the money on a test. i have regretted not testing twice

weigh it first

while im here anyone tested the same lot twice at different labs

is quantity testing available as a separate thing or bundled

is it worth testing if the vial has already been through a warm transit

is a purity-only test worth the money if underfill is the common failure
post the lot, the purchase month, the lab, the number, and what you were expecting. that makes it useful later

do you test every order or sample it

has a supplier ever disputed a result posted here

the results in this channel skew because people test when they are suspicious. that is selection bias and it is real

if the vial has been through a bad transit you are testing the transit as much as the supplier

how many lots do you need before you can say anything about a supplier

my vial assayed under label but the purity was fine, which matters more
