I wanted to see the results of dialing in my batches to get closer to actual mg/ml without overdosing. I am mostly pleased. You are correct that testing the raws first is the best practice. Glad I waited to make the MENT. 93% purity is not what I was expecting, I was told it would be closer to 98%.Raw powder analysis, but you brewed it before getting the results back? You said back in March you weren't going to do that.
