"While on Mepron, I noticed a gradual intensification of depression and psychological manifestations.  At first I was not concerned and just attributed it to temporary hormonal fluctuations or whatever.  As the fourth month approached, it had became much more intense and consistent. I was not making any progress in any other area and I could no longer deny the effect the Mepron was having on me.  Did not help me at all!"
