You need to adjust your cycle. Keep the test at 600mg/week and lower the deca to 450mg/week..
Aromasin has some great properties bro. If you are already running it you may want to up the dosage or start at 12.5mg eod and bump it from there.
You could also try St.John's Wort. It a herbal remedy for the blues. I heard it work well for some people but I haven't tried it.
Get out of the norm. Go have a beer and some pizza with your girl on a Wednesday and bump the cardio up a bit to get the endorphins going a bit higher.
Look at your diet to see how much of your carbs contain sugar and make the adjustments to remove them. You would be very suprised at the difference it can make.
There was some talk on the board about Cialis so I ended up getting a sample for free from the Doctor.... It was the 36hr one. I can't remember that last time I felt like that. I was tap dancing around the house for 3 days with boner on demand...
I got myself a Washburn guitar a while back and now I can play Polly by Nirvana flawlessly. It's the only song I can play, It drive my girl nutts but I don't care... hehe
Point is to get out of the norm and change things up.... Good luck
