Changed my protocol 2 weeks ago after 4 weeks of 175mg of testosterone cypionate per week. Brought it down to 100mg, 50mg 2x weekly. Didn't feel anything the first week, but now I'm feeling as low as you can be. Depressed, low libido, brain fog, and overall blah. I'm still doing great in the gym, but I'm definitely feeling the lows. How long does this last? Will I have to suffer like this for the entire 6 weeks? Starting my 3rd week injection tommorow. Hoping for some relief.
