how do you tell a synthesis house from somebody with a sticker printer

paperwork is worth it

anyone found the price move on a repeat order without warning

price per mg including shipping is the only comparison that means anything

ask for a cold pack

for the archive is it worth paying more for better paperwork

lead times stretch badly around chinese new year. order early or wait it out

is there a supplier anyone would recommend purely on communication

Inter-lab diff for lot B-0114: 99.4% vs 99.2%. Within expected range.

i asked for a non standard vial size and got it without a surcharge. that told me more than any certificate

first order from HJ, anything i should know

QSC has been consistent for me across 9 orders which is what i actually want, not advice obviously

thats the synthesis house

i have never had a problem i could not resolve with GL Biochem, which is a low bar and a lot of suppliers fail it

they slipped

thats a reseller

weigh the vials

whats the smallest order anyone has placed successfully

how many suppliers do people actually keep on rotation
