Question about lethargy/tiredness causes during cycle.

[guest589745]

I am realizing how much more energy I have now that I am off cycle. I forgot what it was like to be back to normal.

Now I know an increase in RBC is supposed to be the common cause of being tired on cycle but what are the other possible causes? Diet/training aside, is there any other cause for this side effect? Is it possible that exogenous testosterone injected can still cause a decrease in ones energy as a result of halted endogenous test production?
