H-Drol is a solid PH but isnt as harsh as say, Sus500 or S-Drol so you DONT HAVE TO use something as powerful as Nolva as a PCT. DONT HAVE TO being the key word. If you can get ahold of it there is really no reason not to use it. If youre taking the more mild route you cant go wrong with Reversitol by I Force and even stacking that with Testabolan V2, but again thats for harsh PCT's. Imo I think youd be fine running Reversitol as a PCT. Use Nolva tho if you have it on hand...why not!
And again, my opinion, but since this is your first PH cycle run the dosage as printed on the bottle. should be just fine!
