I am feeling extremely sleepy on my current cycle which is Test-P and NPP both running at 500mg/wk. Is that simply a side effect or which blood test would be most relevant to run to find out the cause?
Thanks

In my case, was E2 culprit. When it's out of range, lower or higher, tiredness and lack of energy and sleepness, could be a frequent symptoms. Check E2 in first attempt.
