Yep mixed mine w oil 20 ml oil to 10ml of est for the 50mcg dose.Lol I was going to use dianes method directly but hit a money snafu and my impatient streak flared.
I think the “oil” is dpg or cymethicone based because instead of separating like i would have expected it to it blended perfectly w the est which is ethanol based.
Hope this helps.
I’m sensitive to the est so I ended up cutting mine down more so its 25mcg now.
I think diane posted a good instructional for ratios on happykitsunes est post.
