I've experimented around a bunch of different ways. I find the optimal mix is test: primo:deca. So, for instance a cycle would be 200mg each for 600mg total. Or 300mg each for 900mg total. They each serve their purpose, like legs to a stool, you need all three legs for a stool to work.

Primo is the one "leg" that you can safely increase beyond the other 2. So for instance 200mg test+200mg deca+600mg primo would be a great cycle, put you at 1g total/week with minimal sides. You try to increase the other 2 much and you will start to need ancillary drugs to combat side effects that start coming at you.
