i’m considering homebrewing myself and i was wondering about the ratio of ba/bb as well. can the same ratio be applied to all other powders? i ask because the recipes i’ve seen very. for example some use both ba/bb while some use only ba.
It does depend - the BB is there to keep the powder stabl;e and dissolved - i’d put it in anyway to make sure, it harms none, and makes for a thinner liquid.
As for BA 2% has always been painless for me, but i can take a couple of ml in the biceps with minimal pain, that took a long time to achieve.
At 2% it isnt so much the BA causiung issue, it is the experience of the user in my opinion.
