Well to be honest, you seem far too naive to take a steroid right now. No offense intended, but just take time to research. If you are too impatient to do that, then your likely one of the people going to end up screwed up from a cycle.
PCT, technically always have a SERM on hand even if you plan an OTC PCT. That being said epistane is can be pretty mild from what people have reported, so OTC is probably not the hardest thing to pull off...but remember, if you start getting gyno with no SERM or potent AI around your just kinda going to be out of luck. (Though a SERM may only stop it such as Nolva, but Letro and the likes can reverse it)
