Prop making, BA enough or would BA/BB be better

[MrRTTB]

If so why?

Would it be ok to use BA only when making Test prop or would BB be needed, if so Why? I mean if the solution already dissolved in BA only..?

BB hurts less.

havent tried making it with BA only, i think it would require too much to be comfortable shooting it...ive had good results at 100mg/ml 3%BA and 10%BB... the BB thins the oil out and i like it my prop is painless at 100mg/ml
