When to start Finesteride for test cycle.

Just wondering how long before cycle to start finesteride and how long after to continue. Also -cutting proscar into quarters-is 1.25mg per day enough. I've seen people say 5mg per day but I think they are wrong. I am prone to MPB have nizoral, xandox, spiro and finesteride ready. Thanks in advance

it can take upt to 3 month and longer for proscar to become fully effective, so the earlier u start, the better.
