Eh I don't think you're getting it.

After PCT you want to stay in an anabolic environment, lets say that you need to eat at least 2,800kcal to stay above BMR... if you add in clen, then maybe that number is 3,200kcal, so now you have to eat above that number. That's why I'm telling you only diet will really matter.

You can run Proviron in PCT. If you might lose some libido at least the Prov will help keep your d1ck working, and it might help slightly with nitrogen retention, so sure go ahead. But in the end, you're best help in keeping your gains will be a proper PCT regiment and diet, not these other compounds you have your head wrapped around.
