I can't comment on primo , but eq is the most overrated steroid ever , I have run it at over 1200 mg a week for 16 weeks and it does nothing for me , not sure if it's even good to add to my shakes , that said alot have very positive results lol
It's been years since I've run EQ, and I stopped because I thought it was a worthless drug. I was running primo, test and masteron all the same time and that was a solid stack.
