with deca you shouldn't have a problem if you do not use the BB but I have found with substances like EQ it is a bit thick and BB helps to thin it out. BA is an absolute must though for its anti-bacteria properties though. FYI I made some EQ 400 with no BB and ended up thining it out a bit because it was thick - not having BB was a mistake. Live and learn.
Good luck with the homebrew! Make sure to post an update if ya decide to inject what ya made
