Hdrol doses seem okay, as it's a mild PH (and you'll need a stronger dose if you've been on stronger PHs or 'proper' gear before). I would start with 100mg ED and stay with it. I'd also extend the cycle tio six weeks, too. However, that all depends on how much you have and if you want to buy any more. As for PCT, Nolva (or a decent equivalent) is usually hammered home as the main part of PCT, but a few folks on here think you won't need it as Hdrol's not strong enough. Personally, I'd include it and just run it for a short while at lower dose than you would usually.
Do a search for Hdrol on this board as their are tons of threads about the stuff and their cycles. Loads of blogs on it, too. You might find more answers in those.
