like said before, when I use eq I have no prob with gyno, and primo is like anavar, both aren't that strong to cause anything, you may want to take a tab of clomid eod throughout the cycle to help, or just have nolv for an emergency. Primo you really don't have to worry about ,the eq would be the only one imo out of the 2 would give you gyno if you did get it. you should get solid and real cut from those 2
