I just use butter and boil for three hours in water.
I judge potency by eating too much when I make my first batch of cookies out of a given run of butter.
Then I try and eat just one.
I suppose you could start by eating just one but why go about it all backwards?
The last time I had gummies they were 20 mg. I could eat five before I was high as I get with a cookie.
But I just had two cookies and am just as stoned as I prefer to be.
I'm guessing if I were to eat 200 mg I would be around the same dose.
