B1 has a similar dose range to mephedrone for me. 1/5 of my normal M1 dose I doubt I'd even feel, to be honest. I'm not a fan of any of these drugs so far and tend to get all the bad effects and few of the good ones so maybe I just don't get on with them as some do. Only use I have for them is in combo with each other (and a few other things in some cases) when they start to get more interesting. Does seem to be a very wide range of dose and effects for all these bk-type drugs.
