I have.
You will get conflicting answers about this. And if you want to play it "safe", a serm is recommended (how safe it now is with serms in fact...).
But me personally will bot run a serm after a androsterone or epiandro solo cycle. Super PCT from OL is a decent OTC PCT. Add in some Sustain alpha and a good tocco product and I think you are quite gtg.
But again. That's just my way, others will tell you different.
Havn't tried rebirth so I can't say anything about it.
