I'm wondering are there general rules for coming up with a stack other than use what's worked for others before? From what I know the only rules are:
1) Make sure each substance can contribute to your overall goal for the cycle.
2) Make sure each substance won't interact in a bad way with one another (ie., don't stack an aromatizing substance with M Dien because of the risk of progesterone side effects; don't stack methyls, although I think that's more flexible than people say).
I'm just wondering if there's a set of general rules other than these two that can help direct you to develop a decent stack with a good chance of working.
