Bro, I've made 400mg/mL of crystal clear (golden) EQ with just 2% BA. Since EQ is a liquid at temperatures above 50-60° Farenheit, it easily dissolves into oil. You could probably get away with 1% BA and 20%BB (that is what Upjohn uses for their Test Enan 200) and achieve 300mg/mL. I go ahead and use 2/20 BA/BB tho, and its never crashed.
