here's how i takeall that measuing out of home brewing. (laziness on my part and got bored with it a couple of years ago) use a graduated beaker. they are 5 bucks a piece. add powder, solvent and heat til clear (melts). add oil to just above desired amount as the heat causes expansion of solution. heat, stir, filter, bake and shoot. i brewed up 400+ml in less than an hour not including baking. only used 4 filters. 1 for each hormone. 100ml of each. naother reason i go over a bit too is because you always gonna have some waste. so 5% extra oil dont effect potecy to a noticable degree and you get a little 1 or 2 ml extra.
its tough being smart and purdy.
