In all honesty, aqua dex is a staple in any cycle for me now because I have absolutely no water retention with it. I've ran proviron one time and loved it, I ran it at 50mg ED. On the aqua dex I run .5mg EOD or E3D.
If you're already balding like me then proviron should definitely be considered. It adds so much to a cycle that I wish I'd run it years ago.
As for your PCT, you won't need Clomid (aqua clo) and Nolvadex (Nolva Bloat). One or the other is fine, the only time I really use Nolva Bloat is if/when I start showing signs of gyno. But if you're running aqua dex you shouldn't have any issues so I'd stick to Clomid/aqua clo and/or HCG.
