What’s the potiency or dosage or fab-144 and sdb-006

I can’t seem to find anywhere I’m expericend with like amb fubinaca and md mb 2201 but are the potiency s about the same or what’s up with these ones just don’t want to find out the hard way ones a lot stronger or something

Fab-144 dosage is almost identical go that of amb-fub, sdb-006 would be closer to ab-fub in dosage
