What it is actually like to order from the suppliers this community uses: quoted lead time versus real lead time, communication quality, fill consistency, packaging and cold packs, price-per-milligram arithmetic done in the channel, and the difference between a synthesis house and a reseller with a sticker printer.
Pinned in this channel
Price per mg is the only comparison that means anything, and you have to include shipping in it. The arithmetic gets done in this channel roughly weekly.
Ask who actually makes it. A supplier who buys from a synthesis house and relabels is not the same risk profile as the synthesis house.
No sourcing requests by private message. Not from members, not from suppliers. Report anyone who tries.
