Is Nolva required with HCG or just a standby?

Hey bros,

Been using 500iu HCG/day for the past five days mid-cycle which really helped a LOT. My nuts were killing me.

Question is, is Nolva an absolute necessity with HCG in this situation or should it just be handy in case needed? So far, no itchy nips or bloating, but keeping my eyes open.

Thanks ya'll!
