I am almost convinced now that Nolva is the root of the delayed gyno rebound thing. I have always had great effects at gyno reduction with both superdrol and RXT. In fact, RXT is one of the first things I start taking when I start to get gyno! Just don't use Nolva in post cycle therapy and you'll be fine. The RR is ok in post cycle therapy. AIs like letro and anastazole are enzyme inhibitors that can upreg ERs if too much is used for too long. That's why I always recommend super low doses like 0.25mg EOD because that's all it takes. Steroidal AI's that act as irreversible suicide substrates CAN NOT upreg ERs. In fact, many studies show that estrogen remains low even after the drugs are gone from your system. Believe me guys, I wouldn't lie to you and make you risk boobs. I know that sux and I've been doing this a looooong time so try what I'm telling you before you believe all the delayed gyno/AI rebound hype.
