I have read that you should never take finasteride (propecia/prscar) while on deca, and you should wait upto 4 months after the deca to start taking finasteride. I have also heard that the previous statement is bullshit. I want to know if anyone has taken the combintation and what type of hairloss if any has occured. I normally don't do deca, but I got such a good deal that I could not pass it up.
