The only difference between what we do is the order in which its done.It's probably not as accurate this way, especially if you're assuming low purity from the beginning. If you assume less purity it means the raws will displace a different amount of liquid once dissolved. So you can't calculate how much carrier oil you really need based off formulas. Your total volume might be under or over and at that point you're stuck with what you got bc any change will affect the ratio of BB, BA, and concentration of the hormone. That is unless you purposely leave some of the carrier oil out until the very end to get the desired volume.
What I do is figure out the concentration and volume I want to make. Calculate how much raws, BA, and BB I'll need. Fill a beaker to the total volume I want with water using a syringe to be as accurate as possible bc lines on a beaker can be off. Mark the line with a fine point marker. Empty beaker and dry it thoroughly with heat.
Add my raws BA and BB. Heat it till its dissolved. Then I'll add enough carrier oil to get to the line I drew. This way I'll have exactly the concentration I want (assuming the purity is what I assume it is lol) exactly the concentration of BA and BB I want, and the carrier oil volume used is what it has to be to get the correct volume.
I know raws will be cut or stepped on, that's why I figure in 20%.
