Finasteride will affect my testosterone which might affect my mood but I love my energy levels! D.....I'm always hyper and happy, going to the gym perhaps it's due to my testosterone. Lower T level is a huge problem for many men, once depression settled in nothing really matters in life. I personally witnessed that. Does finasteride worth it? If T=leves don't drop that much, I mean, I would love to hear your opinion about it
