Will this affect Protodrol's effectiveness??Thank's.

It shouldn't. Dont see how it would.. Only thing saw palmetto decreases the absorption rate of is Iron.
saw palmetto MAY block 5-ar very mildly (same thing that propecia does only much more mild)
i took saw palmetto for my SD cycle and i dont think it affected anything. Milk thistle did though, not guna take that for liver supp again
