I received my order over the weekend and was really expecting something potent. I used 1 heaping tbsp in each shell, spaced about 10 minutes apart, for a total of 3 shells. I didn't feel much and had to shake up 2 auluballs to finish my session. My normal consumption is 3 auluballs of med grind with 2 tbsp each. That always puts me right where I want to be. I know that the instant is always going to be more expensive due to production costs, but I was hoping it would be more cost effective than I experienced. I'm wondering if my expectations were too high. Should 1 tbsp of instant be more potent than 1 tbsp of med grind, properly prepared?
