RE: any ph or ds that don't shut down your libo
Personally I would not stack hdrol with pp as both are used for different thing i.e.
PP on its own will be great for mass and strength.
Hdrol on its own will be great for cutting.
Based on what you have said you want a straight PP cycle would be good for you. I am currently running pp and my libido if fine, it has actually increased funnily enough.
