There was a guy on elitefitness that used to recommend proviron or anavar for 2 weeks after a cycle. That way the person wouldn't be catabolic as their LH levels recovered. After the two weeks it would be a normal 2-3 week SERM PCT.
I always thought it sounded like a cool idea, but there was definitely people that didn't agree with him. Might be something to try though. If it doesn't work, it's not that big of a deal.
