Well, I just started a cycle of test prop, test suspension, anavar, and T3. Two things are happening right now- I am dead tired (like you said) and I want to eat everything. I don't know why. Nothing has changed in my diet or training or sleeping. Just the addition of the anabolics and T3. If anything has changed, I am eating a bit more carbs (due to the appetite) and sleeping a bit more.
Every other cycle I have done has filled me with aggressive energy. But every other cycle has mainly been full of d-bol and massive doses of enthanate. I am taking a heavy dose of anastrozole, so maybe the lack of estrogen has something to do with it.
