I've loved Primo at a gram alongside 1-1.2g test the last couple of off-seasons. I "feel" nothing, which is what I want - just extra anabolism and decent e2 suppression. Didn't have to use an AI to keep e2 around 60.
But I'm giving EQ another go and may like it even better. I'll have more to say in a couple months, but it feels like it's already more e2 suppressive, which is what I want as long as it's not tanked.
End of the day, for off season, it's mainly a matter of total mg, probably giving the nod to test as far as the most effective thing you can take. I.e. make up as much of your total with test as sides will allow, use the other stuff to fill in the gaps.
