It would not matter about which enzymes are blocked if the theory here holds true lowering androgen levels by any means can cause pfs…pfs imo is more common with finastride because it lowers it immediately and greatly which increases the risk of triggering the syndrome…The other inhibitors are much less potent and effective but cause it in some people…
Seems it takes more androgen reduction ti cause the syndrome in certain people where others can have it triggered by a mild inhibitor…Just my thoughts from observation of users.
